APPARATUS FOR CONTROLLING ELECTRICITY ACCUMULATION APPARATUS, ELECTRICITY ACCUMULATION APPARATUS AND METHOD OF CHARGING AND DISCHARGING ELECTRICITY ACCUMULATION APPARATUS
First Claim
1. An apparatus for controlling an electricity accumulation apparatus on which an electric power from a distributed generation and a grid is stored, comprising:
- an electricity accumulation electric power computation unit that computes a distributed generation'"'"'s share of an electric power that is the electric power from the distributed generation in an electric power that is charged to the electricity accumulation apparatus; and
a discharged electric power computation unit that suppresses an electric power that is to be discharged from the electricity accumulation apparatus to the grid, to the distributed generation'"'"'s share of the electric power, or reports a value of an electric power that is to inversely flow to the grid, as a value of the electric power that is suppressed to the distributed generation'"'"'s share of the electric power.

Abstract
An electricity accumulation device has a dedicated charge terminal that connects to a distributed power generation system such as a solar power generation system and a grid-dedicated discharge terminal that connects to the power grid, a grid-dedicated charge terminal that connects to the power grid and a discharge terminal for discharging to an electric load such as an electric apparatus. The electric power charged to the electricity accumulation device can be made between an electric power generated by the distributed generation and an electric power generated by the power grid, by providing an electric power measurement device for each charge terminal and each discharge terminal that connects to the distributed generation, and thus charge and discharge control can be performed.
