SMART GRID

The is in general is distributed into twolayers, transmission and distribution

The transmission layer is used to transportenergy over long distances with low lossesand to connect big power plants to the grid.

The distribution layer supplies small unitswith energy or connects medium and smallgenerators to the energy system

For an optimal grid operation thetransmission system is highly automated,mainly to facilitate control of voltage andload-flows, using transformers with in-phase regulation, regulation in quadratureand reactive power compensation units. Inaddition using FACTS (for Flexible AC-Transmission Systems).

SMART GRID

What makes smart grid really smart is communication! Communication in smart grid is dividedinto three dimensions:

1. Electrical energy conversion chain

2. Smart Grid Architecture Model (SGAM), In general the zones are used to aggregate andthereby reduce information

3. Interoperability Layers

“SMART GRIDS” Fraunhofer Ise, 2014


MICRO GRID

Micro grid is defined as an interconnected loads and distributed energy resources that aredefined within boundary and are controllable as one entity

Micro grid can be connected or disconnected from the grid (mostly in the LV or MV) where itcan function as both grid tied or off grid system.

Microgrid, depending on its size, can contain one or multiple distributed resources!


WHAT IS A HYBRID SYSTEM? Hybrid system refers to when more than one energy system are combined in a closed controlled

boundaries, making them function as a micro grid!

One of the most common hybrid systems combinations is when PV system used with diesel genset! Electrical storage can be used to improve the performance greatly!

• Solar, Wind, Hydro, Biomass, Wave, Tidal, Geothermal

Renewable

• Diesel Generator, Natural Gas Generator, Grid Connection, etc.

Non-Renewable

• Battery, Fuel Cell, Hydrogen Tank, Capacitor, Flywheel, Pumped Hydro, etc.

Storage

Hybrid control system providessynchronization between solarpanels and diesel gensets, as wellas providing remote monitoringand control.

Batteries can be used to improvethe utilization of solar energywith respect to the gensetgenerated energy as well ac as aspinning reserve.

The $ saving comes mainly fromreducing the consumption of fuel(in this case diesel).

HYBRID SYSTEMS CASE STUDY

SSV labor camp, Yas island, Abu Dhabi. Saved 30-50% of diesel Fuel / emission, and offer 10-20% financial saving.

“Yas labor camp” Enerwhere, 2016



In the Winter, most of the camp runs on ˃95% solar power during the day.




In the summer, solar production and demand form air-conditioners peak nearly at the same time allowing solar to save on the peak capacity leading to major fuel savings.

5. Summary


SUMMARY

1. Reduced cost and cost uncertainty:

• Lowering generation cost by displacing fossil fuels or high electricity tariffs

• Hedging against future volatility

• Lowering O&M costs associated to thermal generation

• Shifting work… synchronizing peak load with cheaper renewables, thus bringing down overall cost of operations

2. Improved reliability

• Increasing energy security… reduced logistical challenges

3. Lower Carbon Emissions

• Reducing carbon liabilities by avoiding emissions

4. Unlocking revenue streams

• Revenue from selling excess generation and providing ancillary services
