摘要：

Medium- and long-term operation is an important part of power system operation, which can effectively deal with the seasonal contradiction of energy supply. In view of the increasing coupling among multiple energy forms, such as electric power, natural gas, and so on, a medium- and long-term operation model and method for multi-energy system are proposed. Considering the seasonal characteristics of renewable energy, the fluctuations of natural gas price and the system operation constraints, the weekly operation model of multi-energy system is established, and the annual unit maintenance plan, the power distribution of hydropower and the purchase and storage plan of natural gas are optimized uniformly. Taking the adapted IEEE-RTS79 system as an example, the correctness and validity of the proposed model and method are analyzed and verified. The results show that the coordinated arrangement of the medium- and long-term operation for multi-energy system can give play to the complementary benefits of different energy forms and improve the system's operation economy. The introduction of gas storage device can relieve the air supply tension in winter and reduce the system's operation cost. © 2020, Electric Power Automation Equipment Editorial Department.
