A low load density county distributed photovoltaic source network coordination planning and configuration system

Abstract

The present application relates to a kind of low load density county distributed photovoltaic source net coordination planning configuration system, belong to distributed new energy grid-connected control and county distribution network operation management and control technical field, for the technical problems of high communication dependence of existing distributed photovoltaic management and control scheme, planning and operation disconnection, security and economy difficult to consider, county remote scene adaptation ability is insufficient.This system is deployed in the local controller of distributed photovoltaic inverter, through the linkage of fusion rule base storage module before grid connection, self-regulation after grid connection, cluster collaborative adaptation, local adaptive iteration module, each module shares the same set of local core variable system, whole process without external real-time communication link and global grid parameter dependence.The present application can reduce the cluster control response time delay to 7.2ms, planning and operation capacity deviation is reduced to 2.1%, photovoltaic local consumption rate is increased to 99.5%, and can be widely applied to low load density county distributed photovoltaic grid-connected management and control scene.
