HEMS scheduling method based on BPSO and comprehensive energy storage strategy

Abstract

The invention discloses an HEMS scheduling method based on BPSO and a comprehensive energy storage strategy, and relates to the technical field of household energy management optimization control, andthe method comprises the steps of building mathematic models of all submodules of an HEMS in a classified manner based on the analysis of working characteristics; dividing working time slots of eachsub-module of the HEMS, and collecting environmental electrical change data; formulating a comprehensive energy storage scheduling strategy of the energy storage system according to the working time slot and the real-time electricity price; and establishing a household intelligent electric equipment optimization scheduling model taking electric charge minimization as an optimization target, and solving an optimal household power utilization optimization plan based on an improved BPSO algorithm. According to the method, the problems of low comprehensiveness, single equipment scheduling and thelike in household energy management are improved, the situations of access of the electric vehicle, multi-terminal regulation and control of a storage battery and an electrical load and the like are comprehensively considered, the efficiency of the optimization process is high, and the method has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of household energy management optimization control, in particular to a HEMS scheduling method based on BPSO and comprehensive energy storage strategy. Background technique [0002] Due to the lack of two-way intercommunication with mains information and dispatching planning of electrical equipment in the traditional household electricity structure, this not only leads to low utilization efficiency of renewable resources on the energy demand side, but also focuses on purchasing electric energy during peak periods of electricity consumption and increasing grid load pressure. The home energy management system (Home Energy Management System, HEMS) is proposed to realize the demand response of the home end, so as to improve the efficiency and quality of electricity consumption of users. As one of the main leading roles of the smart grid, the household demand side, based on the operation of the grid and electric...

Problems solved by technology

[0003] Regarding the research on household energy management strategies, although some scholars have developed a set of optimal scheduling schemes, they have not yet considered the load characteristics and working characteristics of each electrical equipment, and have not carried out targeted classified control scheduling.

In addition, current scholars' research still lacks comprehensive and multi-angle scheduling problem backgrounds, such as the access of electric vehicles, energy storage batteries, and multi-terminal regulation of power loads.
