OPERATION PLANNING DEVICE AND METHOD FOR MICROGRID, AND REGIONAL ENERGY MANAGEMENT DEVICE AND ENERGY MANAGEMENT DEVICE USED BY OPERATION PLANNING DEVICE FOR MICROGRID

摘要

Provided are: an operation planning device and method that can speedily calculate complete optimization of energy cost reduction of power and heat of a microgrid composed of a plurality of sites; and a regional energy management device and an energy management device that are used by the operation planning device of the microgrid. The microgrid is configured so that a plurality of sites are connected to a power system, generators and heat source devices are provided within the sites, and power and heat are supplied to consumers within the sites. The operation planning device of the microgrid is provided with: an energy management device that manages power and heat within the sites; and a regional energy management device that obtains information regarding power and heat in each site from the energy management device, and determines the distribution of power and heat over the entire microgrid. The present invention is characterized in that: the energy management device creates supply and demand plans for power and heat within the sites, creates operation plans for when a waste heat utilization operation is performed in order to use more waste heat within the sites, and sends the supply and demand plans and the operation plans to the regional energy management device; the regional energy management device creates a power supply and demand plan in which the power of a site where the amount of power generation has increased due to a waste heat maximum utilization operation is lent to another site; and the energy management device verifies the power supply and demand plan and the heat supply and demand plan presented by the regional energy management device, and determines the power and heat to be supplied to consumers within the sites.
