Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
Concerning the storage needs of microgrids, electrochemical technologies seem more adapted to this kind of application. They are competitive and available in the market, as well as having an acceptable degree of cost-effectiveness, good power, and energy densities, and maturity. The modularity of electrochemical technologies is another advantage.
Electrochemical energy storage is a shared system. The battery has a unique charging and discharging state. It can accept charging of four microgrids, but can only discharge to two microgrids at the same time. Each microgrid has a hydrogen 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. Fig. 1. System structure diagram. The wind and solar power generation system is the main energy source of microgrids.
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.
