An optimization method of a combined cooling, heating and power system

Abstract

The invention relates to an optimization method of a combined cooling, heating and power supply system, the method comprising the following steps: establishing a model of the combined cooling, heatingand power supply system, selecting a combined cooling, heating and power supply type micro-network as an optimization object to carry out mathematical modeling on the equipment in the scene; determining the decision variables and objective functions of the optimization analysis of the combined cooling, heating and power system; determining the constraint conditions of the optimal operation of thecombined cooling, heating and power system; choosing a whale optimization algorithm and introducing chaotic cube mapping and mutation rules to optimize initial population and behavior rules; adoptinga hybrid heating and power supply strategy as the operation strategy of the combined cooling, heating and power supply system; determining and evaluating the optimized evaluation index. The method adopts the strategy of mixing heat and electricity and applies the improved whale algorithm to solve the combined cooling, heating and power micro-grid model. In the initial stage, the chaotic initialization operation improves the searching ability, and the mutation operation introduced in the trapping stage can find the global optimal value more quickly, thus realizing the purpose of quickly finding the optimal solution for the optimal operation of the combined cooling, heating and power system.

Description

Technical field [0001] The invention belongs to the field of new energy technology, in particular to an optimization method for a combined cooling, heating and power system. Background technique [0002] Energy issues have always been hot issues of concern to all countries, such as the development and utilization of new energy, the construction of microgrids, etc. Among them, the combined with cooling, heating and power (CCHP) microgrid is solving the problem of hotels and buildings. It has been widely used in electricity consumption in places such as supermarkets and supermarkets. The combined cooling, heating and power microgrid replaces the decentralized power supply mode of the traditional power grid. The waste heat generated by the power supply equipment is collected and used for cooling and heating loads. Therefore, its energy efficiency is improved from 59% to 88% compared with traditional power supply methods. %. Among the many research fields related to the combined co...
