PCS efficiency-considered microgrid operation device and operation method

Abstract:

The present invention relates to a power conditioning system (PCS) efficiency-considered microgrid operation device comprising: a scheduling unit for scheduling outputs of a controllable load, a battery, and an emergency internal combustion generator operated in a microgrid; and an operation control unit for controlling the operation of the battery, the emergency internal combustion generator, and the controllable load according to charging/discharging of the battery, the output or the emergency internal combustion generator, and the output of the controllable load, which have been scheduled by the scheduling unit, wherein the scheduling unit schedules charging/discharging by considering the efficiency of a PCS such that a mate of charge (SOC) of the battery is maintained within a preset range. According to the present invention, the microgrid can be efficiently operated by considering the charging/discharging efficiency of the PCS.
