Operation planning device and method of micro grid, and regional energy management device and energy management device used in micro grid operation planning device

摘要

Problem to be solved: to optimize the overall energy cost reduction of power and heat of microgrids.Microgrid operation planning equipmentIt has a heat source that generates heat from generators and generatorsA range of heat energy can be supplied from a generator or heat source through a heat pipeMultiple sites are connected to the power systemEnergy management equipment for managing energy of each siteIt has a regional energy management device which cooperates with the energy management equipment of each site.Each site's energy management device provides power demand and fuel cost functions to the regional energy management device.The regional energy management device creates a power plant operation plan for multiple sites and supplies it to the energy management device of each site, and the energy management device of each site is The operation plan of the heat source machine is made by evaluating the waste heat of the generator in the generator operation plan from the regional energy management equipment, and it is given to the regional energy management equipment.Diagram
