ENERGY MANAGEMENT SYSTEM, ENERGY MANAGEMENT METHOD, MEDIUM, AND SERVER

摘要

According to an embodiment, an energy management system includes estimator, calculator, creator and controller. Estimator estimates energy demand of customer to obtain estimated demand, and estimates power generation amount of renewable power generator to obtain estimated power generation amount. Calculator calculates operation schedule of nonrenewable power generator based on estimated demand and estimated power generation amount. Creator creates strategy maximizes difference between electricity cost loss and profit using push up effect by discharge of battery based on estimated demand and power generation amount, and schedule. Controller controls discharge of battery based on actual value of demand and power generation amount, schedule and strategy.

主权项

1. An energy management system for managing energy of a customer, including a first power generation unit configured to generate power derived from renewable energy, a second power generation unit configured to generate power derived from nonrenewable energy, and a battery device, comprising:
an estimation unit configured to estimate a demand of the energy of the customer to obtain an estimated value of the demand and estimate a power generation amount of the first power generation unit to obtain the estimated value of the power generation amount; a calculation unit configured to calculate an operation schedule of the second power generation unit based on the estimated value of the demand and the estimated value of the power generation amount; 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 battery device, based on the estimated value of the demand, the estimated value of the power generation amount, and the operation schedule; and a control unit configured to control discharge of the battery device based on an actual value of the demand, the actual value of the power generation amount, the operation schedule, and the discharge strategy.
