Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the …
Due to the output characteristics of wind power and photovoltaic power, large-scale access to wind power and photovoltaic power in the grid will lead to wind and photovoltaic power curtailment. Therefore, it is necessary to use pumped hydro storage and electrochemical energy storage to consume new energy. This study proposes a hierarchical optimization …
