General optimized dispatching strategy for combined supply of cooling, heating and power microgrid system

Abstract

The invention belongs to the field of optimized dispatching of combined supply of cooling, heating and power microgrid systems and relates to a general optimized dispatching strategy of combined supply of a cooling, heating and power microgrid system. Based on functions of equipment, the equipment of the combined supply of cooling, heating and power microgrid system is divided into three types, namely source equipment, a convertor and energy accumulation equipment; based on load types, loads are divided into electrical loads, steam loads, hot-water loads and cooling loads; energy buses are divided based on different transmission modes of different energies on the combined supply of cooling, heating and power microgrid system; and various equipment is connected among different buses and on a single bus based on properties. The overall system adopts a bus-type structure, takes bus power balance and equipment operation constraint as constraint conditions to model the combined supply of cooling, heating and power microgrid system, and builds a dynamic economic dispatch model taking the minimum operating cost as an optimization objective to solve problems. The general optimized dispatching strategy of the combined supply of cooling, heating and power microgrid system can effectively solve the problems that the combined supply of cooling, heating and power microgrid system has various types of equipment, is complicated in coupling and difficult in dispatching.
