摘要：
The user-level integrated energy system(UIES) can improve the energy efficiency and economy. A planning process and method of UIES was proposed for practical engineering. Firstly, the overall model and key equipment model of UIES were established to describe the conversion and flow relations of various energies in long-term operation. Secondly, the planning process was put forward containing four steps: preliminary data collection capacity, load forecasting, CCHP capacity pre-configuration, equipment selection and configuration. At the meantime, an optimization planning model was established as well. The model took the construction and operation cost of the full planning cycle as the target, and constraints of maximum load, annual total energy, equipment operation, user construction land and other conditions have been taken into account. The problem was solved using YALMIP toolkit and CPLEX solver through Matlab. Finally, two typical examples verified the validity of the described method in different energy consumption types and energy consumption scenarios. Sensitivity analysis was conducted on key factors such as the annual maximum utilization hours of equipment, the proportion of consumer electrical load, and the price of natural gas. © 2020, Electrical Technology Press Co.
