Abstract

In recent years, distributed integrated energy station has been widely used as an effective way to help China achieve the ‘dual carbon’ goal. As a complex system that integrates energy production, storage and supply, integrated energy station utilizes a variety of renewable energy sources close to the load side. Accurate analysis and optimal scheduling on both sides of supply and demand should be carried out to ensure energy saving effect in actual operation. This article takes an integrated energy station at the park level in Taizhou as the research object, and puts forward a system configuration scheme based on the results of the annual load prediction of the buildings. Then, the system model is built based on TRNSYS simulation platform, and the frequency conversion control strategies of multiple units are analyzed. The influence factors of the energy efficiency of the cooling, heating, electricity and storage multi-energy coupling system are studied by combining TRNSYS with GenOpt. Hooke-Jeeves algorithm is used to synchronously optimize the main parameters of the water pump and photovoltaic panel. The results show that under the same initial investment, the annual energy consumption of the optimized system is reduced by 3%, and the operating cost of 178490 yuan can be saved annually.
