2.HYBRID (DC + HIGH FREQUENCY AC) GRID FOR RESIDENTIAL

SYSTEM Abstract of the project This project is to construct and test a prototype of a HybridGrid system.

Modern conventional houses are fed from alternating current (AC). However, at the same time, many appliances and lighting technologies, such as televisions, computers, and LED light fixtures, are native DC loads, as are electric vehicles, batteries, fuel cells, and renewable sources. These and other appliances are fed from multistage power-conversion equipment that first rectifies the incoming AC into DC. Usually, this is followed by a second DC-to-DC converter stage that converts the rectified DC voltage into a lower regulated voltage as required by the end load (e.g., 12VDC or 5VDC in personal computers). Each of these conversions wastes electricity in the form of heat. A DC house is a new concept, where the power distribution system is built around DC instead of the conventional AC system. The DC house can be fed from the AC electric utility grid (i.e., grid-parallel operating mode) or can be intentionally disconnected from the grid to function as a self-sustaining entity. HybridGrid combines such a DC house distribution system along with an additional high frequency AC distribution system. This high frequency AC grid is employed to perform inter-house power transfer, thus eliminating the dependence on the conventional low frequency AC electric utility grid.

3.LOW COST DISTRIBUTED INVERTER FOR SOLAR GENERATION

SYSTEM Abstract of the project This project is to construct a prototype of a Low Cost Distributed Inverter

(LCDI) for solar PV panels and test it in the laboratory and in actual solar power generation plant. An LCDI unit is placed onto the back of each solar PV panel to convert the DC voltage output of that panel to a switched quasi-square wave voltage with variable pulse width. When these voltages are aggregated across multiple panels connected in a series string, they synthesize an AC waveform that can be interfaced with the power grid. The inverter functionality is distributed along the string, with no micro-inverter, no central inverter, and no voltage boosting required. The LCDI represents the best of both worlds in inverter concepts. Like micro-inverters and solar optimizers, the LCDI enables panel-level MPP tracking to achieve 10-15% greater energy yield under non-uniform conditions than central inverters. Also like micro-inverters, the LCDI avoids the use of large electrolytic capacitors that can severely limit lifetime in central inverters. When illumination is uniform across the string of panels, the LCDI enjoys the high efficiency of string inverters – up to 98%. The control system switches into a mode where each LCDI independently acts like a low-power, low voltage pulse-width modulated string inverter. The switching, conversion, and filtering requirements in an LCDI are much simpler than in micro-inverters and solar optimizers. As a result, an LCDI bill of materials consists of ~20 components rather than the 150-450 of other module-level electronics.

4.VIRTUAL POWER PLANT (VPP) CONTROL & OPERATIONS #1 Abstract of the project VPPs do represent a possibility for the utility of the future with high

penetration of distributed power, energy storage and renewables. The large-scale integration of renewable energy and energy storage systems have introduced many technical and economic challenges. High levels of installed renewable capacity might reduce grid stability and power quality. Increased adoption of renewables and energy storage by customers on the distribution level might lead to new business models for the utilities. The VPP concept has the potential to provide both technical and economic solutions to the integration of distributed generation. The distributed resources on a utility distribution system collectively work as an integrated power generating system as a VPP with smart control algorithms and real-time analytics. The proposed VPP has forecast and analytics capability with distributed electrical resources and components integrated through an integrated dispatch and control system. The load and resource forecast generates the dispatch schedule for power production and ancillary services for each resource on the VPP and loads. This is done by taking historical load and weather data, models of the VPP resources, demand response, market data and the weather forecast as inputs. The electrical systems controllers use the dispatch schedule to regulate power production from each individual resource and loads. Grid frequency regulation, voltage-VAr support and inertia emulation techniques are implemented. A demonstration VPP with solar photovoltaic, battery energy storage, loads, demand response, analytics and forecasting capability, is presented and implemented using a real-time digital simulator and scaled hardware in the loop (HIL) components. The results validate the VPP performance with load forecasting, power production, demand response and generator inertia emulation. With this demonstration system, individual small-scale power stations will collectively work as a virtual power plant, enabled to participate in energy markets for both power production and ancillary services.

Tasks Students will work with power modeling and may work on real-time system models simulating and forecasting power production and energy storage. Students will integrate hardware like PV inverters, energy storage and distributed resources on a Hardware-in-the-Loop (HIL) laboratory.

Requirements Masters majoring in Electrical Power Systems, Power Electronics, Energy Analytics and Industrial Engineering.

6.ENERGY STORAGE OPTIMIZATION FOR ANCILLARY SERVICES Abstract of the project This project is integrating an energy storage management scheme

to maximize potential value for energy storage that can be brought forth to medium voltage feeders. In general, the potential performance benefits produced by possible energy storage applications include improved system reliability, inertia and spinning reserves, frequency regulation, transmission and distribution (T&D) capacity enhancement and deferrals and energy arbitrage to minimize peaks. Here we propose a unique control algorithm that enhances coordination of all the ancillary services applications, voltage-VAr support along with renewables capacity firming and ramp-rate control. Optimization of control parameters, set-points and resource forecasting should be developed to maximize energy storage lifetime and revenue streams through ancillary services. The design needs to be tested on a Real-time Dynamic Simulation and forecasting platform which shows that the performance of the different functions.

Tasks Students may expect to have a power system modeling experience and may work on real-time system models simulating and forecasting power production and energy storage. They may also integrate hardware like PV inverters, energy storage and distributed resources on a Hardware-in-the-Loop (HIL) laboratory.

13.Coupling of Dynamic Line Rating with Temperature-Dependent

Line Model Structures Abstract of the project This project proposes to investigate and formulate the coupling of

temperature-dependent transmission line models that are able to account for longitudinal non-uniformities in line parameters, with dynamic line rating techniques, leading to a novel methodology to estimate transmission network parameter and model structure of an electric power system. This would result in increased accuracy in estimates of network loading capabilities and system voltage stability indices. With the ever-increasing demand for electric power, in conjunction with the significant push for and subsequent increase in distributed generation connected to the existing network, transmission and distribution lines are now operating beyond their nominal ratings. This makes the grid increasingly vulnerable to service interruptions and blackouts. The lines represent, now more than ever, the primary limiting constraint to reliable and affordable delivery of electricity. Given practical limitations posed on infrastructure upgrading, the optimized use of the existing assets is of paramount importance. It is then essential to accurately determine network operating conditions, for both off-line and on-line applications allowing for optimized planning and operation of the system. By increasing the level of detail in the line model, and releasing select historical modeling assumptions, more accurate determination of the network operating conditions is expected. The proposed research activities will provide a framework to study electric power systems by incorporating environmental conditions as new degrees of freedom in the line models. The focus will be on adaptive determination of transmission network model and of system transfer capability limits. The main research goals are to: 1. analytically investigate ambient condition-dependent power line models, including longitudinal non-uniformity in line parameters due to gradients in external conditions, 2. develop effective system applications tools, capitalizing on acquired theoretical knowledge, with special attention on estimation of line power handling capabilities, and 3. validate and evaluate the performance of resulting system models and application tools.
