MANAGEMENT METHODE OF ESS ANDSOLAR GENERATOR

摘要

In an operation method of a power supply system including a photovoltaic power generation system and a power storage device as the operation method of the power supply system including the photovoltaic power generation system and the power storage device, the present invention relates to the operation method of the power supply system including the photovoltaic power generation system and the power storage device which performs an ESS residual capacity detection step (s100) and a charge and discharge selection step (s200) according to a residual capacity, performs a necessary charge process (s300) including a photovoltaic power generation state confirmation step (s310) and a photovoltaic power and system power charge selection step (s320) if the residual capacity is less than or equal to a predetermined value, and performs a charge and discharge selection step (s400) including an electric charge comparison step (s410), a charge process (s420) according to a charge unit cost, and a discharge process (s430) according to a discharge unit cost if the residual capacity exceeds the predetermined value.
