Abstract: In order to improve its power generation efficiency and output power, and ensure the sustainability and stability of the system, the optimisation study of building solar thermal photovoltaic heating system considering stability is carried out this time. This method first analyses the operating principle of photovoltaic heating systems used in buildings, then constructs an output power model of the photovoltaic heating system, and fully considers the stability of the heating system operation to design an objective function. Finally, based on the improved Particle Swarm Optimisation with Adaptive Elite Strategy Algorithm (PSO-AESA), the output power model of the photovoltaic heating system is solved, and realise optimal control of photothermal photovoltaic heating systems for buildings. The experimental results show that the total power generation efficiency and output power of the heating system are higher after the proposed method is used to optimise the control. The system control is better than the comparison method, and has high-application value.
