Description

technical field [0001] The invention relates to the technical field of building energy management, in particular to an optimization control method and device for a building energy management system. Background technique [0002] With the rapid development of urbanization, the proportion of building energy consumption in my country's total energy consumption has increased rapidly, and the energy consumption per unit building area is relatively high. Based on this situation, building integrated photovoltaics has attracted widespread attention. BIPV is an expansion of solar energy applications and an innovative application of photovoltaic technology in intelligent buildings. At present, photovoltaic power generation systems integrated with buildings mainly refer to grid-connected photovoltaic power generation systems. [0003] The building energy management system is the decision-making center for the energy regulation of the building system. Its task is to manage and control ...
