Description

technical field

[0001] The invention relates to a real-time simulation device and a simulation method for a photovoltaic cogeneration system, and belongs to the technical field of cogeneration simulation equipment. Background technique

[0002] With the continuous exploration of new energy sources, solar energy utilization technology has developed very rapidly in recent years. However, in order to achieve more efficient and reasonable utilization of solar energy, more in-depth research on solar energy conversion technology is still required. Generally, the power generation efficiency of solar photovoltaic cells is about 15%, and the remaining more than 80% of the solar radiation is absorbed by the panels and converted into heat energy. As the temperature of the solar cell increases, the power generation efficiency decreases. In addition, solar cells work under high temperature conditions for a long time, and the life of battery components will be greatly shortened. Object...
