Comprehensive energy system economic optimization scheduling method based on micro-grid

Abstract

The invention discloses a comprehensive energy system economic optimization scheduling method based on a micro-grid. The method comprises the steps that independent modeling is performed according toenergy production equipment, energy conversion equipment and energy storage equipment in a factory, and an energy supply structure for a comprehensive energy system based on an energy exchange networkis set up; considering a serial working mode and a parallel working mode of an ice storage air-conditioning system, a comprehensive energy system economic optimization scheduling model is further improved, so that the optimization model better meets the practical demand of a project; and optimization scheduling is performed on the micro-grid considering cold and hot electric balance constraint, equipment operation constraint and energy storage equipment constraint with minimum annual operation cost composed of operation and maintenance cost, electricity purchasing cost, fuel cost and stored energy depreciation cost being an optimization objective, and automatic optimization of the factory is realized. The method has the advantages that energy using efficiency at the user side is improved,energy using cost of a user is reduced, economic benefit and the energy utilization rate are increased, and the method is suitable for different types of industrial park comprehensive energy systems.

Description

technical field [0001] The present invention relates to the related technical fields of integrated energy and electric power demand response, in particular to a microgrid-based economically optimized scheduling method for an integrated energy system. Background technique [0002] The integrated energy system (IES) is a next-generation intelligent energy system, which enables systematic, integrated and refined operation and management of energy production, transmission, storage and use of the energy system.
