In general, photovoltaic power generation systems are becoming an attractive alternative to increasing energy usage due to the development of industries and cities as pollution-free and endless resources.

Since the solar power generation system changes in a specific time zone, a specific location, and a specific weather condition, it is necessary to take into account the time-dependent load and the power generation efficiency characteristic of the solar energy. In order to maximize the energy efficiency of the solar power generation system, Type micro grid system is required.

FIG. 8 shows a solar power generation system (including a solar power generation system and an energy storage function) having a general energy storage function. The conventional solar power generation system includes a PV module, a power conversion device (PCS) System (EMS), and an integrated operations center.
