ENERGY MANAGEMENT SYSTEM, ENERGY MANAGEMENT METHOD, COMPUTER-READABLE MEDIUM, AND SERVER
First Claim
1. An energy management system for managing energy of a customer, including a connector connected to a vehicle including an on-vehicle battery and capable of sending/receiving power to/from the on-vehicle battery, and a power generation unit configured to generate power derived from renewable energy, comprising:
- an estimation unit configured to estimate a demand of the energy of the customer to obtain a demand estimated value and estimate a production amount of the power of the power generation unit to obtain a production amount estimated value;
a creation unit configured to create a discharge strategy capable of maximizing a balance obtained by subtracting an electricity purchase loss from an electricity selling profit using a push up effect of a sold electricity amount by discharge of the on-vehicle battery based on the demand estimated value and the production amount estimated value under a constraint for use of the on-vehicle battery; and
a control unit configured to control discharge of the on-vehicle battery based on an actual value of the demand, the actual value of the production amount, and the discharge strategy.

Abstract
According to an embodiment, energy management system manages energy of customer, having vehicle with battery, and a power generator. Energy management system includes estimator, creator, and controller. Estimator estimates demand of customer to obtain demand estimated value, and estimates power production amount of power generator to obtain production amount estimated value. Creator creates discharge strategy capable of maximizing differential between electricity purchase loss and electricity selling profit using push up effect of sold electricity amount by discharging battery under constraint for use of battery. Controller controls discharge of the battery based on actual values of demand, production amount, and discharge strategy.
