Zhejiang Huadian Jiande Dayang Photovoltaic Co-located Energy Storage Project
The installed capacity of this energy storage project is 15MW/15MWh, which includes two energy storage units. The charging and discharging power of each energy storage unit is 7.5MW, and they are respectively connected to two 35kV busbars in the 110kV substation. The grid-forming energy storage system possesses the characteristics similar to those of a synchronous generator and can actively provide voltage and frequency support for the power grid. When there are fluctuations in photovoltaic power output or grid faults occur, it can respond rapidly to maintain the power system stability. It can smooth the photovoltaic power output, enhance the reliability and stability of photovoltaic power generation, and improve the power quality. In the event of a grid fault, the grid-forming energy storage system can quickly reconstruct the local power grid and supply power to critical loads.
