Research on energy efficiency optimization of grid-connected photovoltaic system based on fuzzy logic

With the development of the economy, the requirement of energy saving and emission reduction of the green shipping industry is becoming higher and higher. Application of photovoltaic power generation is important to reduce the pollution and emissions from ships. The application of photovoltaic system on the ship is still in the development stage, so there are still many problems worth studying. In this paper, based on the grid-connected photovoltaic system, the optimal allocation of various energy sources and the optimization of ship energy efficiency were studied. According to the different demands of different working conditions, the energy efficiency improvement method of ship electric photovoltaic system based on fuzzy logic was presented. The results showed that the energy efficiency could be improved by using this method to make a reasonable allocation of different energy sources.
