Design of Multi-machine Cooperative Photovoltaic Energy-saving Disinfection System

With advancements in science and technology, environmental hygiene has gained increasing attention. To protect the environment, a multi-machine cooperative photovoltaic energy-saving disinfection system has been designed, utilizing solar energy for power supply and implementing a priority charging control strategy to facilitate the collaborative operation of devices. The photovoltaic array consists of 150 Wp solar modules, and the design’s feasibility has been validated through simulations using PVsyst software. Additionally, the priority charging strategy has been simulated in Simulink, determining the charging priorities based on state of charge (SOC) values. The final analysis indicates that the system is expected to reduce coal consumption by 1.11 tons in the first year, resulting in reductions of 3.12 tons of CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and 7.426 kg of SO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions.
