Utility Scale Storage System also shifts the energy of one time period to another time period for peak load management during the day time. It has features such as high energy density, fast response and high accuracy power control.
In addition to peak load management, Energy Storage System as part of transmission system has additional benefits such as;
- Renewable Energy Integration & Intermittency control
- Frequency regulation
- Black start
- Voltage Control
- T&D system upgrading deferral
ESS is also used for integration of renewable sources like solar and wind systems which are intermittent in nature. It smoothen the fluctuations generated by the renewable energy sources.
