Study and development of user-level integrated energy simulation analysis system

In order to properly control the layout of integrated energy systems in the planning stage, give full play to the advantages of efficient operation of integrated energy systems, and combined with the actual construction needs of distributed integrated energy stations, the design ideas of logical framework, simulation method and functional modules of the user-level integrated energy simulation analysis system are proposed, and the energy integrated energy simulation analysis system is developed using the Visual Studio enterprise application platform. The system takes the overall economic benefits, operational benefits, and comprehensive energy efficiency of the system as optional optimization targets, comprehensively considers the load levels of different seasons, system operation mode, system resource allocation and other factors, and automatic generation of optimal configuration schemes for integrated energy systems through load analysis, capacity configuration, and optimized operation. It also has different optimization scheme design comparison function. Taking a user-level integrated energy park as an example, the calculation and analysis results are basically consistent with the proposed construction scale in the feasibility study report of the actual distributed energy station project, which fully demonstrates the effectiveness and practicability of the simulation analysis system.
