Functional Description Virtual Generator Mode and Grid Support Mode

1MZB100055 5-1

5. Functional DescriptionThis section describes the PowerStore Battery functionality. And also a selection of system use cases is described in thissection.

5.1 Virtual Generator Mode and Grid Support Mode1

The PCS is configured through parameter settings to meet the specific requirements of a specific site and application. At thehighest level, one of two inverter operation modes is selected:

• Virtual Generator Mode (VGM) is used in isolated or weakly grid-connected Microgrids or in Microgrids that can transfer between on-grid and off-grid operation. In VGM the PowerStore Battery operates as a Voltage Source Inverter.

• Grid Support Mode (GSM) is used in larger isolated, electrically stiff Microgrids or in permanent grid connected networks. In GSM the PowerStore Battery operates as a current source inverter.

To support the explanation below the difference between the PowerStore Battery configurations VGM and GSM areillustrated in Figure 5-1.

A conventional generator is illustrated on the left-hand side of Figure 5-1. It is comprised of the following key aspects:

• Dynamic frequency and voltage controllers to maintain system voltage and frequency continuity

• Frequency controls through fuel flow into a thermal engine

• Voltage controls through the excitation current of the alternator via an Automatic Voltage Regulator (AVR).

1. GSM is not envisaged in the four products at present. Future applications may include the GSM as well.

Figure 5-1: Illustration of PowerStore Battery Operation Modes

Virtual Generator Mode Functional Description

5-2 1MZB100055

The PowerStore Battery in virtual generator mode is illustrated in the centre image in Figure 5-1. When compared to aconventional generator, it can be seen that the thermal engine is replaced by the battery and inverters. These changesaside, the dynamic controllers and control scheme remain of the same type. In accordance with the conventional generatoroperation, connection to the network is through Voltage Source Inverters (VSI). Using these type of inverters the systemworks similar to a synchronous generator and has:

• Dynamic frequency and voltage controllers that operate continuously.

• Frequency controls through real power flow to and from the battery.

• Voltage controls through the inverter setting the voltage and providing reactive power.

The final image on the right-hand side demonstrates the PowerStore Battery in grid support mode. In this case the systemdoes not behave like a generator. The primary distinction from conventional generator operation is that the connection tothe network is made through a Current Source Inverter (CSI). When operating in this mode the system functions with:

• Static Frequency and voltage support mechanisms that operate once the frequency and voltage have exceeded set points.

• Frequency support via real power flow to and from the battery.

• Voltage support through the inverters providing reactive power.

It is important to note that due to the typical application objects in terms of energy and power as well as necessary gridsupport functions, the use of the virtual generator mode configuration is the typical use case for the PowerStore for themajority of customers - as a result is the default module offered.

5.2 Virtual Generator Mode

Looking now in further detail, Virtual Generator Mode allows the PowerStore Battery to operate on the grid with an effectsimilar to traditional fossil fuel based generators. In this inverter operation mode, the PowerStore Battery is capable ofserving as the only generator on the grid. As a result, it is especially suited to the following types of applications:

• Small isolated grids with large proportions of system generation serviced by renewable energy generators,

• Applications that utilise the PowerStore Battery as the only generator on a network (e.g. renewable only mode / diesel-off mode),

• Applications that require the smooth transitions between being the only generator and operating in parallel to diesel generators (i.e. load sharing), or

• Supporting the smooth segregation of a downstream network section from the main network, be the dominant generator on the islanded segment and conversely smoothly reintegrating into the main network (for example following an operator request).

When operating in VGM the PowerStore Battery supports the grid by providing:

• Frequency control

• Voltage control (STATCOM)

• Peak shaving

• Frequency and voltage reference (Standalone)

The frequency control of the PowerStore Battery is comparable to the control of a conventional generator. The advantage ofthe PowerStore Battery is that its response is adjustable. Through parameter tuning, performance is adjusted to enhancesystem dynamics with nearly all types of generators and where required match the response of onsite machines to facilitatepassive load sharing functionality. Artificial inertia makes the PowerStore Battery dynamic behaviour adjustable to behavelike a conventional generator in the response to load or generation changes. Through using large inertia values you canallow the machine to appear as a very stiff electrical unit, or conversely with low inertia achieve highly dynamiccharacteristics. The frequency control dynamics are easily adjustable through dedicated converter parameters.

Voltage control is similar to that provided by conventional generators through their excitation system. The PowerStoreBattery voltage controller is adjustable in a similar manner to the PowerStore Battery frequency controller (i.e. through themeans of parameters).

A demonstration of the frequency control arrangement through an example of frequency control / active power provisioncan be seen in Figure 5-2. A similar profile can be expected when trying to visualise voltage support (albeit much faster).

Functional Description Virtual Generator Mode

1MZB100055 5-3

In the example below, user can witness the effects of renewable system intermittency. Here a wind turbine trip event hascaused a step load on the remaining grid system. On the left hand side the response of a conventional generator is shown.User will notice that initially the generator contributes power through its inertia and then the power slowly increases with thefuel flow. This causes a deep sag in the system frequency (often leading to under frequency trip events).

With the inclusion of the PowerStore Battery however, the sag in frequency becomes significantly smaller. Through itsnature the conventional generator still contributes some power, but the PowerStore Battery takes over the responsibility forservicing the load prior to network frequency reduction. Following the event the load is slowly passed back to theconventional generator. The same behaviour could be observed for a sudden load decrease in the system.

PowerStore Battery Controller

1MZB100055 6-1

6. PowerStore Battery ControllerThe PowerStore Battery comes with a dedicated controller known as the PowerStore Controller (or more simply asPowerStore Automation), The controller is responsible for integrating the power conversion equipment into the powersystem.

The PowerStore Controller is a member of the ABB Microgrid Plus distributed control system family, packaged specially forthe PowerStore Battery, meaning it can be used as a member of Microgrid Plus or as a standalone device.

The controller is delivered pre-programmed to meet the application needs. During system commissioning, the functionalityis adapted to the variable site and network conditions by parameter adjustment.

Using standard interfaces - field wiring and industry protocols such as Modbus RTU and TCP controller interfaces to theconverter system, and the battery system. In order to communicate quickly and effectively the state of the battery system aconnection is made to a dedicated device known simply as the Battery PLC. The Battery PLC is responsible for making adirect high speed connection to the BMS for large data set monitoring and provides signal aggregation and fault analysisprocesses upstream to the PowerStore Controller.

In regards to interfacing to external control systems, the PowerStore Battery Controller seamlessly integrates with othermembers of the Microgrid Plus family to form part of a cohesive distributed control system, however this is not mandatory.Alternatively, the PowerStore Battery Controller is capable of operating as a standalone device, i.e. without the PowerStoreBattery being integrated within the Microgrid Plus.

Interfacing to off-the-shelf SCADA systems is also available through Ethernet communications ports made available fromthe PowerStore Battery using Modbus TCP.

Figure 6-1 shows a high level / conceptual interface scheme between the controller and primary electrical component withinthe PowerStore Battery.

PowerStore Battery Microgrid Enabling Functions PowerStore Battery Controller

6-2 1MZB100055

6.1 PowerStore Battery Microgrid Enabling Functions

Due to its unique characteristics and specialised software, the PowerStore Battery can provide (or support) a series ofdifferent Microgrid enabling functionalities (also known as application cases). Table 6-1 provides a list of PowerStoreBattery functions.

6.1.1 Standalone

Renewable only operation is only possible under the virtual generator configuration. Due to inverter configurations suchoperation is not possible when the PowerStore Battery is under GSM.

Renewable only operation is possible when the power from renewable energy sources is sufficient to provide the systemload and sufficient stored energy capacity is available.

When a Microgrid is operating in a grid connected mode, the utility provides a reliable reference for voltage and frequency,necessary to maintain the synchronous operation of the Microgrid. However when a Microgrid is isolated from the grid, itmust utilise its own internal generation assets to provide this service. Currently, most isolated Microgrids rely on fossil-fuel-fired generators for this.

A unique challenge for isolated Microgrids is the ability to source the load entirely from renewable generation. Such systemsare typically entirely inverter-based, lacking grid forming capabilities as well as the provision of spinning reserve.

Through its unique configuration the PowerStore Battery is capable to operate in a grid forming mode without any fossil fuel-fired generators allowing for such a scenario (Standalone or Diesel-off mode). It operates in voltage and frequency controlmode, providing its own reference for frequency and voltage.

As a result the core Standalone function of the PowerStore Battery enables a fully renewable Microgrid.

How does it function

During transitions to renewable only operation, all conventional generators are switched off with the PowerStore Batteryinstantly taking over as the voltage and frequency reference to the grid. In this mode the PowerStore Battery is responsiblefor maintaining the balance between generation and consumption. Short term imbalances in the generation consumptionmix are compensated by the PowerStore Battery. In the event that the PowerStore Battery moves outside of the state ofcharge limits, renewable only operation is suspended through the dispatch of fossil fuel generators. Although thePowerStore Battery is not directly responsible for this generator dispatch event, it does provide signals to generatorautomation systems to allow dispatching to proceed. ABB's Microgrid Plus automation system provides this functionalityseamlessly.

Typical use cases

• Remote or isolated Microgrids

• Minimisation of fuel consumption

• Back-up/black-start power

• Increase in supply reliability

PowerStore Battery Controller Stabilisation

1MZB100055 6-3

6.1.2 Stabilisation

Maintaining steady station frequency is crucial for keeping any power network (utility grid or Microgrid) balanced andoperational, as well as for protecting sensitive loads. If generation and loads become in-balanced in a power system, arapid series of automatic protection processes can rapidly evolve into load shedding in order to prevent a total systemcollapse.

Effective frequency regulation is more often, more challenging in a Microgrid than across a large interconnected grid - duein part to the dynamic properties of the Microgrid. Furthermore, system operators typically have access to a much largerand more diverse portfolio of grid assets that can be used to stabilise the frequency.

When a Microgrid is isolated from the main power system, the ability of its components, to cope voltage and frequencyvariations is essential. The same capability can be beneficial to the main system when the Microgrd is operated on-gridoperation. PowerStore Battery, having the ability to instantaneously react to frequency and voltage fluctuations, providesthis service to the system, even in fully renewable scenario.

PowerStore Battery core Stabilise function is essential for maintaining Microgrid stability in both off and on-grid scenarios.


In the event of frequency/voltage movements below a certain threshold, power/reactive power will be injected automaticallyto restore the station frequency/voltage to within safe limits.

In the event of frequency/voltage movements above a certain threshold, power/reactive power will be absorbedautomatically to restore the station frequency/voltage to within safe limits.

Typical use cases

Both in grid connected and isolated systems:

• In an isolated network the size of the Microgrid and its capability to influence the frequency is critical.

• In unstable grids with fluctuating loads and dynamic generation, such as Wind and / or Photovoltaic sources.

6.1.3 Seamless Transition

Through the use of the PowerStore Battery it is possible to seamlessly transition between the two states: Grid Connectedand Isolated and conversely from Isolated to Grid Connected. One can consider this falls into two categories either as aplanned transition or unplanned transitions


Planned Transitions based on operator requests, the Microgrid can be disconnected from the power grid. Utilising theinherent grid forming and regulation functions of the PowerStore Battery transitions to isolated mode are managed. Thetransition is smooth, so there are neither interruptions in supply nor frequency deviations. Following the disconnectioncommand the PowerStore Battery takes over Microgrid power production (real and reactive) to cover the load that isrequired by the isolated network. The same approach is used for reactive power. Once the power flow is shifted the gridbreaker is opened and Microgrid continues to operate as an isolated system.

Conversely, by operator request, the Microgrid can be automatically reconnected to the power grid. To achieve this thefrequency, voltage and phase angle of both grids must be synchronised prior to reconnection. The synchronisationfunctions are made possible through the provision of the PowerStore Battery. Once synchronised the circuit breaker closesand connects the Microgrid to the Power Grid. After that the power generation in the Microgrid can ramp down as powersupply will be handed back to Power grid.

Unplanned transitions to islanding is usually based on a fault condition in the power grid. In that scenario the protectionrelay at the connection point will identify the fault and operate the circuit breaker. Pending on configuration, instant availablegeneration, as well as speed of disconnection from the fault, the Microgrid can continue to operate without outage throughthe rapid response of the PowerStore Battery.

Typical use cases

• Fringe of grid applications (weak grids) with regular outages or line loading issues

• For maintenance reasons in areas with single incoming feeds

PowerStore Battery Ancillary Services PowerStore Battery Controller

6-4 1MZB100055

6.2 PowerStore Battery Ancillary Services

In addition to the application, use, a series of ancillary services are also embedded within the PowerStore Controller. Theseare summarised below.

6.2.1 Battery Charge Control

The charge level (SoC) at which the battery normally operates at varying levels between full and empty duringcommissioning.

The normal maximum and minimum SoC is set depending on the application to ensure there is both, sufficient energyheadroom to carry out the required frequency and voltage control task, and to ensure that the battery can be charged withthe rated power without reaching any DC voltage limitations. The maximum allowable absolute power levels for charging ordischarging can be set to the inverter rated power as a fixed parameter, or adjusted dynamically during operation (e.g. to atrickle charge value if the SoC is high).

6.2.2 Protection Functions

The PowerStore Battery has a number of protection systems in place, including but not limited to:

• Mains over-voltage and under-voltage protection

• Over-/Under-frequency trip

• Inverter over-current protection

• Unintentional Islanding protection (if required)

• Power limiting in the event of an inverter failure

The PowerStore Battery automatically reduces its maximum rating in the event that the inverter system detects an overtemperature. This ensures on-going operation even during high temperatures. Likewise, if the PowerStore Battery detectsthat there has been an inverter module failure the maximum power rating will decrease accordingly.

6.2.3 Backup Power Supply

In the event of a mains failure, the control system is buffered by a UPS integrated in the PowerStore Battery. While theauxiliary power to the inverters and any (optional) HVAC system will be interrupted during the mains outage, the controlsystem enables an automatic restart when mains power returns. Additionally, depending on the project requirements, analternative mains LLP supply connection can be present for extended periods of backup auxiliary power supply.

6.2.4 Spinning Reserve Reduction

Isolated power systems require the provision of spinning reserve to allow for the sudden increase in load or the sudden lossof generation plant. Spinning reserve is usually provided by conventional generators. As a result, generators cannot beoperated at their rated power output where the fuel efficiency is usually the highest.

The PowerStore Battery is able to provide spinning reserve for the power system and allow generation plant to operatecloser to their rated power output, or, temporarily, to be turned off.

6.2.5 Fault Ride Through

The PowerStore Battery is able to ride through faults, providing grid stability in case of a loss of a generator or large systemdisturbance.

The PowerStore Battery is capable of providing real and reactive power to support the system under the followingscenarios:

• When the system voltage is depressed

• During a fast rate of system frequency change

• During an instantaneous voltage phase shift.

The above events usually occur during line faults within the distribution system. The PowerStore Battery has been designedto ride through those distribution faults, provide system stability and support the system recovery after the fault has beencleared. The PowerStore Battery remains connected to the network during line faults up to configurable thresholds induration and magnitude of the fault.

PowerStore Battery Controller M+ Visualisation

1MZB100055 6-5

6.3 M+ Visualisation

M+ Visualisation is achieved through a dedicated touch panel HMI. Further information on this can be obtained from thePowerStore Battery Operations Manual.

If required (as an optional extension), M+ Operations can be offered in place of the HMI, which is also defined in furtherdetails in the Operation Manual. M+ Operations can be accessed remotely, thus allowing operation and maintenance of theplant remotely. Microgrid Plus Operations is the web environment used to monitor and control ABB Microgrid Plus System.Using this feature the asset owner(s) or off-site engineer (s) is able to engineer the setup, commission, operate and servicethe Microgrid Plus System and its MGC600s (in the event that a wider automation system is required).

A Microgrid energy management system offers visualisation, controllability and recording of most of the important variablesfrom PV plant, generators, wind turbines, feeders, and the PowerStore Battery, among others. However, the M+ Operationis in essence not a SCADA system, so we have not included any detailed monitoring.

Following are the key features of the M+ Operations:

• Data acquisition of all monitored points

• High resolution trending

• Web based visualisation

• Remote firmware update and parameter configuration of controllers

• Local and remote data access to all power station data through HMI

• Generator priority scheduling configuration

• Alarm system and event reporting

• Customizable according to Customer’s specifications

• Secure remote access through dedicated VPN and login access code

• Connection to external SCADA or off-site data acquisition systems possible through Modbus TCP or RTU

• The M+ Operations can also be accessed by an authorised operator using an existing computer at the Project facility.

The M+ System does not perform any automatic reporting and any performance report of the evaluation is excluded.

6.4 Remote Monitoring

To support remote network visualisation a dedicated SSL connection is made between the Remote portal and the siteinstalled Industrial PC. Prior to the commissioning of the M+ System an internet connection shall be provided. The Internetconnection will also allow remote monitoring and support during the life of the project.
