Microgrid can be configured with or without energy storage. Some microgrids based on traditional power supply have sufficient regulation and supply capacity, which can promote the reliable consumption of new energy, ensure that the electrical quantity indexes such as frequency and voltage are within an acceptable range, and maintain the stable operation of the system. Therefore, energy storage can not be configured.
In addition, microgrid can also expand to multi energy comprehensive supply. The coupling of electricity, heat, cold, gas, hydrogen and other energy sources is becoming more and more common at the terminal, and the energy demand of users also presents comprehensive characteristics. The complementary utilization of multi energy coupling is of great help to improve the energy efficiency and enhance the flexibility of the system. At present, the multi energy coupling microgrid also shows a good development prospect.
