Abstract

The invention provides a comprehensive energy system multi-objective optimization scheduling method considering the human body comfort, and the method comprises the steps: considering the comfort of auser in the optimization scheduling of the comprehensive energy system, building a PMV model according to the perception of a human body for heat, and describing the feeling of the user for heat supply; describing the dissatisfaction degree of the user to the heat supply by predicting the dissatisfaction degree PPD, and determining the value range of the PMV by setting the PDD; and establishing aheating load model and various energy equipment models of the comprehensive energy system; setting constraint conditions, wherein the constraint conditions include a user comfort degree constraint, an energy balance constraint, an equipment output constraint, an electricity purchasing power constraint and a storage battery constraint; establishing a multi-objective optimization model by adoptinga hierarchical sequence method in consideration of various indexes such as cost, carbon emission and primary energy utilization rate; and finally, solving the established optimal scheduling model based on software to obtain an optimal scheduling result of the system and each objective function value. Example analysis verifies the effectiveness of the method in optimal scheduling of the comprehensive energy system.

Description

technical field [0001] The invention relates to an energy system, in particular to a multi-objective optimal scheduling method for an integrated energy system. Background technique [0002] Energy is the basic source of power for human survival. Adjusting the energy structure, seeking transformation and breakthroughs in the energy industry, and realizing efficient use of energy and sustainable development are the focus of today's society. The traditional energy supply system is composed of electric power system, thermal system and natural gas system. Each subsystem operates independently of each other. There are common problems such as independent energy supply, low level of cascade utilization, energy waste and environmental pollution. In order to improve this situation, Energy Internet, The concept of integrated energy system has been proposed one after another, breaking the traditional existing model, and building a unified integrated energy system has become the only way...

AI Technical Summary

Problems solved by technology

In the research of integrated energy systems, cost, carbon emissions, and energy utilization efficiency are usually used as optimization goals, but there are often conflicts between multiple goals, and it is generally difficult to achieve the optimum at the same time. Optimizing only with a single goal may cause The optimization results of some objectives are not satisfactory, so it is necessary to build a multi-objective optimization model to improve the comprehensive benefits of the system
