Microgrid IEC TS 62898-2-2018: group of interconnected loads and distributed energy resources with defined electrical boundaries that acts as a single controllable entity and is able to operate in both grid-connected or island mode. IEEE: a group of interconnected loads and Distributed Energy Resources (DER) with clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to enable operation in both grid-connected or island modes . PEA Thailand 2
Energy Storage System ( ESS) • To accumulate energy produced by large, less responsive thermal generation plants (also RE) and then re-dispatch it based on peak demand. • Storage facilities were largely financed by arbitrage (buying energy at a low price and 5% OF PEAK DEMAND < 100 HOURS selling it at a higher price). 25000.00 95% of Peak = 22809 MW : 87 Hours per year • Energy storage currently contributes to 90% of Peak = 21609 MW : 650 Hours per year 23000.00 21000.00 reliability, efficiency, power quality, 19000.00 System Gen (MW) transmission optimization, black-start functions, 17000.00 15000.00 and support Demand Response (DR) function. 13000.00 11000.00 9000.00 1 834 1667 2500 3333 4166 4999 5832 6665 7498 8331 9164 9997 10830 11663 12496 13329 14162 14995 15828 16661 17494 Hours ( x 2 ) PEA Thailand 3
