Building comprehensive energy scheduling method and system, storage medium and computer equipment

Abstract

The invention provides a building comprehensive energy scheduling method and system, a storage medium and computer equipment. According to the method, e Equivalent modeling is carried out on a photovoltaic power generation system, random charging and discharging behaviors of an electric vehicle and a dynamic thermodynamic process of a building, and a problem model based on mixed integer linear programming is obtained through conversion; a model prediction control method and a day-ahead scheduling control strategy are used; collaborative optimal control of building comprehensive energy facilities including a photovoltaic power generation system, an electric vehicle and a building load is realized; the permeability of photovoltaic power generation in a power system can be improved, random charging and discharging behaviors of an electric vehicle are controlled while energy crisis is relieved, power is supplied to a building load through discharging of a battery of the electric vehicle, and the peak load pressure of a power grid is reduced.

Description

technical field [0001] The present invention relates to the technical field of smart grids, and more specifically, to a building integrated energy scheduling method, system, storage medium and computer equipment. Background technique [0002] Among the energy consumed by the building, the energy consumption of the air conditioning (AC) system used to adjust the indoor temperature balance accounts for a large proportion. During the peak load period in summer, its proportion even reaches 30% to 40% of the total load. %. Therefore, through reasonable and effective control of the air-conditioning load, the air-conditioning system can quickly respond to the dispatch of the grid side, which is of great significance to improve the efficiency of building energy use and reduce the power demand and distribution network burden during peak load hours. [0003] At the same time, under the background of the rapid development and maturity of photovoltaic power generation technology, more ...

Problems solved by technology

[0004] However, with a large number of electric vehicles connected to the grid in recent years, it has brought new challenges to the reliable operation of the power system: the centralized charging of electric vehicles It may lead to load tension in some areas. The superposition of electric vehicle charging time or charging behavior during peak hours of electric load will increase the burden on the distribution network and reduce the power quality of the power grid.

[0005] However, for the above problems, the ex
