Megawatt-scale energy storage systems are an indispensable key component of modern power systems. They are like energy “reservoirs”, playing an important role in the power grid by peak shaving and valley filling, stabilizing the power grid, and improving energy utilization.
Release stored electrical energy during peak electricity consumption to relieve power grid pressure; store excess electrical energy during low electricity consumption periods to improve power grid operation efficiency.
Smooth out the fluctuations of renewable energy sources such as wind power and photovoltaics, provide auxiliary services such as frequency and voltage regulation for the power grid, and enhance power grid stability.
Store the originally wasted electrical energy and release it when needed, reduce energy waste and improve energy utilization efficiency.
Provide emergency power supply when the power grid fails or power is cut off, ensuring the continuous operation of important loads.
Grid frequency regulation and peak shaving
Wind farms or photovoltaic power stations
Large factories, data centers, hospitals,hotels etc.
Remote areas or islands
