Active power distribution network building thermal load control method and device, electronic equipment and storage medium

Abstract

The invention relates to an active power distribution network building thermal load control method and device, electronic equipment and a storage medium, and belongs to the technical field of power system operation and control. The method comprises the following steps: establishing an optimal control model for the building thermal load of the active power distribution network according to a preset heat transfer model of a building envelope and a power flow equation of the active power distribution network; converting the optimal control model of the building thermal load of the active power distribution network into a Markov decision process model; training the model of the Markov decision process to obtain an optimal strategy function for controlling the building thermal load of the active power distribution network; and according to the optimal strategy function for controlling the thermal load of the active power distribution network building, realizing the thermal load control of the active power distribution network building. According to the method, efficient and stable operation of the heating ventilation air conditioning system in the building can be guaranteed under the condition that a complete thermal model is lacked, peak regulation auxiliary service is provided for a power grid on the premise that the thermal comfort level of a user is met, and meanwhile the operation loss of the network is reduced.

Description

technical field [0001] The disclosure belongs to the technical field of power system operation and control, and in particular relates to a method, device, electronic equipment and storage medium for controlling building thermal loads in an active distribution network. Background technique [0002] With the rapid development of social economy, the important role of thermal load equipment in improving building energy efficiency, promoting environmental protection, and reducing greenhouse gas emissions has gradually become prominent. my country's building energy consumption accounts for about a quarter of the country's total energy consumption, and affected by factors such as urbanization and population growth, this growth trend will continue for a long time in the future. Especially in the heating and cooling of buildings, the extensive use of heating, ventilation and air conditioning (HVAC) equipment as building terminal equipment has led to a further increase in the peak-to-...

Problems solved by technology

[0005] However, accurate power distribution system and building heat load models are often difficult to obtain, and their complexity limits the performance of traditional model-based optimization methods, resulting in deviations in measured parameters that may cause errors in controlled loads during actual operation. movement, resulting in a result that deviates from the optimal operating state
