Industrial estate distribution network collaborative planning method in consideration of multi-energy coupling characteristics

Abstract

The invention discloses an industrial estate distribution network collaborative planning method in consideration of multi-energy coupling characteristics, comprising the following steps: S1, investigating the user scale and the industrial development general situation of an industrial estate and collecting information; S2,predicting the energy demand of the industrial estate; S3, establishing various types of energy resource output characteristics models; S4, according to the energy characteristics of the industrial estate, constructing a planning plan objective function and establishing an energy resource constraint condition; S5, according to the analysis of comprehensive energy resource coupling characteristics, analyzing and matching various types of resources; and S6, evaluating the economic and social benefits of the comprehensive energy planning program and obtaining a comprehensive energy synergy collaborative final plan. The method first constructs the planning plan objectivefunction based on bi-level planning, scientifically and reasonably carries out comprehensive energy collaborative planning for the industrial estate on this basis, can obtain a good comprehensive energy collaborative planning plan to compensate for the volatility of renewable energy, and realizes energy interaction and gradient utilization in the industrial estate.

Description

technical field [0001] The invention relates to the field of energy planning, and more specifically, relates to a method for collaborative planning of distribution networks in industrial parks considering multi-energy coupling characteristics. Background technique [0002] At present, the traditional industrial park planning method is mainly based on the power supply scheme. The planning method at the single energy network level such as the power system and the thermal system has been relatively mature, but the planning research on the comprehensive energy system is still immature, and there is a lack of perspective from the user demand side. It is not enough to study energy characteristics, from multiple links such as energy production, transmission, conversion, storage, and use, to study the coupling relationship between various energy sources in an integrated energy network. Carry out the demonstration application of integrated energy industrial parks, break the tradition...
