Energy storage

Large-scale energy storage mainly refers to energy storage system products used on the power generation side and the grid side of the power system . Large-scale energy storage can be mainly divided into the following uses:

Wind power station energy storage

The energy storage system can improve existing wind power stations with high on-grid electricity prices, solve the problem of wind abandonment, eliminate random fluctuations in wind power, improve the quality of power output from wind power plants, make wind power dispatchable electricity, and participate in peak load and frequency regulation.

● Reduce wind curtailment and improve economic efficiency.
● Smooth random output fluctuations and improve power quality.
● Improve power forecast accuracy and reduce grid shock.
● Wind farm energy storage participates in auxiliary services.

Thermal power station energy storage

The energy storage system has the advantages of quick response, high precision and accurate regulation. It can cooperate with thermal power plants for joint frequency regulation to make up for the frequency regulation characteristics of thermal power units, such as slow speed, low precision and wrong direction (overregulation).

● Fast speed
● High precision
● Accurate adjustment

Photovoltaic power station energy storage

Energy storage systems can improve existing photovoltaic power stations with high grid-connected electricity prices. They can solve the problem of photovoltaic power station abandonment, eliminate random fluctuations in photovoltaic power, and improve the quality of photovoltaic power plant power output. They can make photovoltaic power dispatchable and participate in auxiliary services such as peak load regulation and frequency regulation.

● Reduce abandoned light and improve economic efficiency
● Improve power prediction accuracy and reduce grid shock
● Smooth random power fluctuations and improve power quality
● Photovoltaic power station energy storage participates in auxiliary services

Grid energy storage

The energy storage system can realize peak load regulation and frequency control, monitor load fluctuations in real time, respond quickly to grid dispatch, and improve grid frequency stability. The energy storage system can also dynamically adjust the grid reactive power according to changes in the grid power factor, reduce system losses, and ensure reliable operation of the grid.

● Power frequency regulation and peak regulation
● Independent participation in ancillary services
● Secondary frequency regulation, paid peak regulation, AVC, spinning reserve, cold reserve, black start
