According to the calculation of material cost of 7.5 yuan / kW and repair cost of 27 yuan / kW, the average annual operation and maintenance cost of 10000 kW / 20000 kwh is 345000 yuan. Based on the above analysis, we can get the energy storage investment cost boundary of 10000 kW /20000 kwh, as shown in Table 3 below.
The onboard battery as distributed energy storage and the centralized energy storage battery can contribute to the grid''s demand response in the PV and storage integrated fast charging station. To quantify the ability to charge stations to respond to the grid per unit of time, the concept of schedulable capacity (SC) is introduced.
