ENERGY MANAGEMENT SYSTEM, ENERGY MANAGEMENT METHOD, AND PROGRAM

摘要

According to an embodiment, an energy management system manages energy of a customer, including a power generation device configured to generate power derived from renewable energy and a battery device capable of being charged and discharged. The energy management system includes an estimation unit, a creation unit, and a control unit. The estimation unit estimates the demand of the energy of the customer to obtain a demand estimated value, and estimates the power generation amount of the power generation device to obtain a power generation amount estimated value. The creation unit creates the charge and discharge schedule of the battery device, which can minimize an electricity purchase cost using the push up effect of an electricity selling profit by discharge of the battery device, based on the demand estimated value and the power generation amount estimated value. The control unit controls the battery device based on the charge and discharge schedule.
