Pumped storage, as the most mature energy storage type with the largest installed capacity, has always received a great deal of attention. At the same time, the high-efficiency battery power station also has a broad application prospect for a reduced cost. Figure 1. Geographical locations of the two selected power stations.
Compared with that of electrochemical power stations, although the initial investment of pumped storage power stations is relatively large, the longer operating life lowers the cost of pumped storage stations that are evenly allocated to each year and obtains higher IRR.
In the energy market, energy storage stations gain profits through peak-valley arbitrage. That is, the energy storage system stores electricity during low electricity price periods and discharges it during high electricity price periods.
