If power transmission is allowed between microgrids, simultaneously configuring hydrogen energy storage and electrochemical energy storage is the most cost-effective and environmentally friendly solution. The investment price of hydrogen energy storage is the most important factor affecting the allocation of energy storage capacity.
However, increasingly, microgrids are being based on energy storage systems combined with renewable energy sources (solar, wind, small hydro), usually backed up by a fossil fuel-powered generator. The main advantage of a microgrid: higher reliability.
Among them, the installed capacity of wind and solar power in the four microgrids is the same, both of which are 400 MW, the results are shown below (Table 1, Table 2; Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8). Table 1. Configuration results of mixed energy storage capacity for multiple microgrids. Table 2.
The wind and solar power generation system is the main energy source of microgrids. When the wind and solar power generation is sufficient, the excess electricity is absorbed by the energy storage system.
Each microgrid is composed of four parts: wind and solar power generation system, hydrogen energy storage system (including electrolytic cells, hydrogen storage tanks, and fuel cells), shared energy storage system, and power load.
