Building integrated energy system control method and system based on comfort

Abstract

The invention relates to a building integrated energy system control method based on comfort, which is used for realizing multi-energy complementation, energy conservation and emission reduction on the premise of ensuring the comfort, and comprises the following steps: 1) establishing a power grid interactive energy management system by considering two dimensions of energy efficiency and power grid interactivity; 2) constructing a target function of a power grid interactive energy management system; 3) taking the temperature comfort level and the user power utilization comfort level as constraint conditions; and 4) solving the objective function of the power grid interactive energy management system to obtain an optimal control scheme considering the temperature comfort level and the userpower utilization comfort level, and executing scheduling. Compared with the prior art, the method has the advantages of considering the user power utilization comfort level and the temperature comfort level, reducing the system operation cost, being good in engineering realizability and the like.

Description

Technical field [0001] The present invention relates to the field of building integrated energy system control, in particular to a comfort-based control method and control system for building integrated energy system. Background technique [0002] Data shows that although large public buildings only account for 4% of the total urban building area, their energy consumption accounts for 22% of the total energy consumption of urban buildings. Among various types of buildings, office buildings and large public buildings have a large total energy consumption. , With the characteristics of low energy efficiency and large energy saving potential, the power supply form of the urban power system is changing from a centralized form to a centralized and decentralized form. Distributed energy and energy storage are increasingly used in building energy conservation The use of new energy is also more extensive. Buildings are not only consumers but also energy producers. Building energy-saving ...

Problems solved by technology

[0003] In recent years, my country's building energy conservation work has achieved remarkable results. The comprehensive energy management system of smart communities based on the Internet of Things has achieved the reduction of comprehensive energy conservation in the community through embedded system integration technology and cloud computing. Although the home energy center has been established based on micro cogeneration , but lacks a detailed elaboration on heat load; although the optimal operation model of a multi-energy system including multi-energy carrier production and transmission systems and interconnected smart energy hubs is established, only the curtailable characteristics are considered, and most of the above energy management systems only consider one flexible load with this characteristic, and failed to take into account the comfort of the user while saving energy, and there is a conflict between the degree of energy saving and the degree of comfort
