Concurrently, the energy storage system can be discharged at the peak of power consumption, thereby reducing the demand for peak power supply from the power grid, which in turn reduces the required capacity of the distribution transformer; thus, the investment cost for the transformer is minimized.
Almost any solar systems of any scale include an inverter of some type to allow the power to be used on site for AC-powered appliances or on the grid. Different types of inverters are shown in Figure 11.1 as examples. The available inverter models are now very efficient (over 95% power conversion efficiency), reliable, and economical.
Mechanical energy storage consists of several techniques, amongst which compressed air energy storage (CAES) and pumped hydro storage (PHS) are established for long-term charging and discharging.
The load is supplied by the superior power grid separately from 01:00 to 05:00. During the period from 06:00 to 08:00, the load is transferred by the power flow. Period of 09:00 and during the period 18:00–19:00, the load is jointly supplied by the renewable energy, energy storage or/and power flow transfer.
During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
