To improve the accuracy of capacity configuration of ES and the stability of microgrids, this study proposes a capacity configuration optimization model of ES for the microgrid, considering source–load prediction uncertainty and demand response (DR). First, a microgrid, including electric vehicles, is constructed.
Finally, the article analyzes the impact of key factors such as hydrogen energy storage investment cost, hydrogen price, and system loss rate on energy storage capacity. The results indicate that reducing the investment cost of hydrogen energy storage is the key to reduce operating cost of multi microgrid hybrid energy storage system. 1.
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. Fig. 1. System structure diagram. The wind and solar power generation system is the main energy source of microgrids.
High peak-to-valley differences on the load side also affect the stable operation of the microgrid. To improve the accuracy of capacity configuration of ES and the stability of microgrids, this study proposes a capacity configuration optimization model of ES for the microgrid, considering source–load prediction uncertainty and demand response (DR).
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.
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.
