Optimal configuration and operation of multi-energy complementary distributed energy systems

Abstract

In order to optimize the configuration and operation of multi-energy complementary distributed energy systems, based on the existing optimization methods, this paper proposes an improved comprehensive evaluation model: the improved model comprehensively evaluates energy-saving, economic and environmental performance of the system, and factors including off-design condition performance and start-stop performance have also been considered. After the model is established, a certain virtual building is optimized based on the genetic algorithm, and equipment capacity and hourly equipment operating load are obtained. By comparing the improved model proposed with the simplified model, it can be found that the results obtained from the simplified one cannot meet the actual needs of the system and is unreasonable, thus validating the rationality of the improved model.
