ENERGY RESOURCE-GRID-LOAD AUTOMATIC CONTROL SYSTEM OF SMART MICROGRID AND CONTROL METHODS THEREOF

摘要

The present invention relates to an energy resource-grid-load automatic control system of smart microgrid and control methods thereof, which belong to the field of microgrid control and electrical technology. The energy resource-grid-load automatic control system comprises a distributed renewable energy power generation module, a distributed renewable energy inverter module, a conventional power generation module, a user load module, a bidirectional grid-connected control module, a distributed renewable energy intelligent optimizing power generation control module, an energy storage module, an intelligent energy storage unit adjuster and a storage battery pack. Compared with the conventional microgrid comprising a distributed renewable energy power generation system, the present invention guarantees the stability and the high energy utilization of the power generation system and effectively solves the problem of non-uniform frequency of use of storage batteries to unify the service life of the storage battery pack.
