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.
Demonstrates the future perspective of implementing renewable energy sources, electrical energy storage systems, and microgrid systems regarding high storage capability, smart-grid atmosphere, and techno-economic deployment.
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.
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.
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.
