Abstract: Under the background of dual-carbon goals and regional high-quality development, the park, as the core unit of industrial agglomeration development, has become an important platform for promoting the high-quality development of China's regional economy and regional implementation of the "dual-carbon" strategy. This paper takes the zero-carbon park integrated energy service system of a national agricultural park as an example, combined with the relevant optimization operation strategy of photovoltaic power generation system, this paper introduces the zero-carbon park integrated energy service solution, which includes the clean alternative scheme of the park integrated energy system, the multi-energy complementarity of grid, load and storage, the optimization of energy efficiency improvement, and the intelligent energy management system of energy and carbon double control, which has very considerable promotion significance.
