Distributed energy isolated island detection method for energy storage power station based on active and passive combination

In order to improve the distributed energy output control ability of energy storage power station,it is necessary to detect the distributed energy island of energy storage power station,and a method of distributed energy island detection based on active-passive combination is proposed.Firstly,the real-time load optimal distribution model of the energy storage power station is analyzed,and the real-time load prediction of the energy storage power station is carried out by using the distribution gain scheduling method,and the output conversion control of the energy storage power station is performed in real time.Then,according to the total load of the energy storage power station group,the distributed energy information evaluation of the energy storage power station is adopted,and the method of active and passive combination is used for the distributed balance control of the energy storage power station.Finally,the output load regulation is carried out through the load overhead of the three layers of the power station to realize the distributed regulation of the energy storage power station and the command control of the total generation load,and the distributed energy island detection of the energy storage power station is realized.
