Resident energy consumption double-target optimization method based on regional energy center

Abstract

The invention provides a residential energy consumption double-target optimization method based on a regional energy center. The method comprises the specific following steps: firstly, collecting energy consumption information, environment information and energy conversion electric appliance information of resident users in a region, regional energy center equipment parameters and energy sales prices; secondly, constructing a resident energy consumption double-target optimization model by taking the minimum resident energy purchase cost and the minimum user discomfort as targets; then, converting the multi-objective optimization problem into a single-objective optimization problem by using a weighting coefficient, and uniformly changing the weight distribution of an objective function to obtain a Pareto front; and finally, solving an optimal compromise solution of resident energy consumption double-objective optimization based on the fuzzy membership degree, and performing resident energy consumption optimization according to the optimal compromise solution. According to the resident energy consumption double-target optimization method provided by the invention, the flexibility ofmulti-energy conversion of the resident energy conversion electric appliance and the regional energy center is fully utilized, the economy and comfort of resident users can be considered, and simultaneous optimization of multiple energy consumption of residents is realized.

Description

technical field [0001] The invention relates to the technical field of residential energy optimization, in particular to a dual-objective optimization method for residential energy based on a regional energy center. Background technique [0002] The energy consumption of buildings such as residents accounts for about 40% of the total energy consumption, and with the development of the economy, the energy consumption of residents is increasing year by year. The optimization of residential energy consumption can not only save costs for users and improve the economics of energy consumption for users, but also promote the transformation and development of energy structure. It has received extensive attention in recent years. [0003] Literature (Zhang Tiefeng, Li Qian, Zuo Lili.
