Research and Demonstration of Operation Optimization Method of Zero-Carbon Building Complex Energy System Based on Day-Ahead Planning and Intraday Rolling Optimization Algorithm

Complex energy system is an important component of zero-carbon building. Due to the complex form of the system and the difficult to capture the characteristics of thermoelectric coupling interaction, the operation control of zero-carbon building energy system is difficult in practical engineering. Therefore, it is necessary to carry out relevant optimization methods. This paper investigated the current research status of control and scheduling of complex energy systems in zero-carbon buildings at home and abroad, selected a typical zero-carbon building as the research object, analyzed its energy system operation, and proposed an operation scheduling algorithm based on day-ahead flexible programming and day-day rolling optimization. The multi-energy flow control model is developed to optimize the operation strategy of heat pump, photovoltaic and energy storage systems. Then, the paper applied the algorithm model to a typical zero-carbon building project, and verified the actual effect of the method through the actual operation data. After applying the method in this paper, the self-absorption rate of photovoltaic power generation in the building increased by 7.13%. The research results provide theoretical model and data support for the operation control of zero-carbon building complex energy system, and help promote the market application of complex energy system.
