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 existing technical solutions have not been able to control and optimize the integrated photovoltaic energy system of buildings connected to electric vehicles, especially for photovoltaic power generation Optimal control of building-integrated energy facilities for systems, electric vehicles and air-conditioning loads

In addition, there are still some errors in the prediction of photovoltaic power generation in the current technical solution, which leads to inaccurate control optimization of the overall system model
