Electric heating cooperative optimization operation method

Abstract

The invention relates to an electric heating cooperative optimization operation method. The electric heating cooperative optimization operation method comprises the steps that first an equivalent thermal parameter model of electric heating equipment is established; then a temperature utility model of an electric heating load is established, then the maximum power limit of a power system which allows electric heating and power generation and the minimum start and stop time of the electric heating equipment are taken as constraints, the goal is to optimize the comfort degree of heating for users, an objective function and constraint conditions are established, and an integrated environment optimization scheduling model is formed based on non-regenerative electric heating equipment. Electricheating users in a study area are concentrated in a dispatching layer, the proposed integrated environment optimization scheduling model based on the non-regenerative electric heating equipment is used for solving, an optimal power dispatching scheme is obtained and transmitted to each intelligent control systems of the electric heating equipment, and an intelligent electric heating network whichoperates intelligently is formed. The electric heating cooperative optimization operation method can effectively solve the problem of a load spike and power loss caused by the non-regenerative electric heating equipment in a simple operation mode, effectively improves the temperature effect of the users, controls the load peak value of the power system, reduces the running cost of the system, andensures the heating economical efficiency of the users.

Description

Technical field [0001] The invention relates to the field of optimized dispatching of electric power systems, in particular to a method for coordinated and optimized operation of electric heating. Background technique [0002] Heating in winter is an important part of the basic living needs of residents in northern China. For a long time in the past, coal was the main source of energy for heating systems. However, the excessive consumption of coal and fossil fuels has caused serious environmental problems. Although in the past few years, the Chinese government has encouraged the use of natural gas instead of coal as the energy supply for the heating system, China’s natural gas reserves are not abundant and cannot provide sufficient Energy supply. The lack of natural gas and increasingly serious environmental problems have prompted people to find new heating methods in winter. [0003] Electric heating, as a new type of clean heating method, uses clean and efficient electric ener...
