Steady Power Control for Isolated Microgrid Based on Battery SOC

In order to better balance the source and load of Isolated microgrid and reduce the disadvantages of over reliance on prediction information for energy management in the past, three steady-state real-time power control methods based on expert rules, droop like characteristics are adopted for different operation modes and scenarios on the basis of research on the change trend of SOC (state of charge) state of energy storage battery and engineering practice To ensure that energy management can not only regulate the power of microgrid according to the range of energy storage SOC, but also adjust the output power and load power of distributed power supply in an anti linear way according to the real-time scheduling strategy with droop like characteristics. In addition, coordinate the abandonment of the power of distributed power supply and reduce the load power , which can realize the energy balance management and power control of microgrid.
