Energy management apparatus and method, energy management system, and operation planning method for energy management system

摘要

In an entity consisting of a power receiving business and a power generation business, a self-contracted transfer plan is created by considering the uncertainties of multiple production schedules at a manufacturing plant, and power demand is changed by adjusting the production schedule. To keep the same amount as planned. An energy management device for an enterprise having a power generation business and a power reception business connected to an electric power system, wherein an EMS is installed in the power generation business and the power reception business, an AEMS is installed in the business, and the power reception business is installed. EMS predicts the power transition of each production line on the scheduled date and classifies the operation schedule of its own production line on the scheduled date into a fixed schedule, an undetermined schedule, and an adjustable schedule. The determined demand on the scheduled date and the maximum demand in consideration of the undetermined schedule are determined from the classified operation schedule and the power transition on the scheduled date reported from the EMS, and the difference is calculated as the difference between the maximum demand and the contracted power of the power receiving establishment. The self-contracted transmission output to the power receiving establishment is set within the minimum self-contracted amount and the determined demand, and the EMS of the power generation MS is characterized by generating in accordance with the self-wheeling schedule output that defines.
