Demands and challenges of energy storage technology for future power system
The capacity of GW level energy storage application will be more mature and the cost will drop to ¥500–700 per kWh as shown in Figure 3. The installed capacity is expected to exceed 100 GW. A 100% PV power supply system is analysed as an example. Considering the scheme of 100% PV power supply island sending out through a DC transmission
