Research on Planning Method of Park-level Integrated Energy System Considering Multi-objective Collaboration

The integrated energy system can promote the local consumption of renewable energy, realize the rational use of resources, and improve energy efficiency by complementary advantages of multiple energy sources. The paper considers typical day system operation, and the capacity allocation optimization model is established with the objective function of the total economic cost, pollutant emission and the lowest annual primary energy consumption in the whole life cycle of the system. Finally, according to the data of a business park in Beijing, the feasibility of the proposed approach to planning has been verified through simulation, and the optimal capacity planning of the system has been realized, which provides theoretical foundation and technical support for the planning and design of the integrated energy system.
