Micro-grid

• ESS for renewable energy – Smooth volatile power

generated from solar or wind

• ESS for conventional plant– Control the power quality– Enhance efficiency • ESS for transmission and distribution

– Maintain the power quality – Enhance efficiency

• ESS for end-user– Enhance the power quality– Saving energy cost

ESS Application Overview

1010

Major ESS Applications

Spinning reserve

• Power reserve for conventional power plant

• Utilization of full capacity without reserve allocated

• Provision of additional capacity on grid by masking power fluctuation

Asset optimization

• Stabilization of grid’s frequency from fluctuation

Frequency regulation

• Stabilization of volatility of renewable energy

• Shifts of actual moment of power supply

Renewable integration

• Filling gaps between power demand and supply

Load following

• Restoration of grid when blackout happens

System restart

• Benefiting price gap between light and high load period

• Charging at lower price and discharging at higher price

Arbitrage

• Cutting peak load and saving energy cost

Peak shaving
