Technical FAQs 4

What is the largest grid-forming energy storage station in China?

This marks the completion and operation of the largest grid-forming energy storage station in China. The photo shows the energy storage station supporting the Ningdong Composite Photovoltaic Base Project. This energy storage station is one of the first batch of projects supporting the 100 GW large-scale wind and photovoltaic bases nationwide.

What is Ningxia power's energy storage station?

On March 31, the second phase of the 100 MW/200 MWh energy storage station, a supporting project of the Ningxia Power’s East NingxiaComposite Photovoltaic Base Project under CHN Energy, was successfully connected to the grid. This marks the completion and operation of the largest grid-forming energy storage station in China.

How is the load supplied by the superior power grid?

The load is supplied by the superior power grid separately from 01:00 to 05:00. During the period from 06:00 to 08:00, the load is transferred by the power flow. Period of 09:00 and during the period 18:00–19:00, the load is jointly supplied by the renewable energy, energy storage or/and power flow transfer.

Why should power grid enterprises use multi-point centralized energy storage stations?

For power grid enterprises, multi-point centralized medium and large-scale energy storage stations will be conducive to the reinforcement of the distribution network and the sustainable consumption of renewable energy.
