Method and system capable of optimizing and controlling micro-network energy-storage system

The invention belongs to the field of power distribution network scheduling and management, and provides a method and a system capable of optimizing and controlling a micro-network energy-storage system. In full consideration of a distributed power supply and the characteristics of the energy-storage system, through real-time data monitoring for the active power outputted by a photovoltaic power generation system and a wind power generation system as well as the active power of the storage battery terminal voltage and the energy-storage system, combined with user' side requirement response, the requirement for stabilizing power network power and projection data of electricity utilization load, the optimization and control for the energy-storage system are realized, so the requirement of a micro-network system power balance is met, the impact on an external power network from the micro-network system is reduced, safe operation of the whole power network is ensured, the requirement of the micro-network system stabilizing the power network power fluctuation and the requirement of demand side response are met, the operation time of the micro-network system in an insulted inland is greatly prolonged, the service life of the storage battery is prolonged, and the operating stability, compatibility and economical efficiency of the micro-network are improved. Therefore, the invention has better practical significance for the popularization and application of the energy-storage system in the micro network.
