As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
Through the incorporation of various aforementioned perspectives, the proposed system can be appropriately adapted to new power systems for a myriad of new energy sources in the future. Table 2. Comparative analysis of energy storage power stations with different structural types. storage mechanism; ensures privacy protection.
In addition, by leveraging the scaling benefits of power stations, the investment cost per unit of energy storage can be reduced to a value lower than that of the user’s investment for the distributed energy storage system, thereby reducing the total construction cost of energy storage power stations and shortening the investment payback period.
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.
