Photovoltaic wind power pumped water and energy storage reform of central enterprises

What is a photovoltaic system?

This system is equipped with a photovoltaic (PV) system array, a wind turbine, an energy storage system (pumped-hydro storage), a control station and an end-user (load). This whole system can be isolated from the grid, i.e., a standalone system or in a grid connection where the control station can be the grid inertia capacity.

Can wind and solar power be integrated into the supply grid?

However, solar and wind are variable energy sources and difficult to align with demand. Hydropower already supports integration of wind and solar energy into the supply grid through flexibility in generation as well as its potential for storage capacity.

Why is China building pumped-storage hydropower facilities?

China is building pumped-storage hydropower facilities to increase the flexibility of the power grid and accommodate growing wind and solar power. As of May 2023, China had 50 gigawatts (GW) of operational pumped-storage capacity, 30% of global capacity and more than any other country.

How will hydropower support the integration of wind and solar energy?

Hydropower already supports integration of wind and solar energy into the supply grid through flexibility in generation as well as its potential for storage capacity. These services will be in much greater demand in order to achieve the energy transition in Europe, and worldwide [1, 2].
