Abstract:
In view of the characteristics of rural multi-energy supply and demand under the new rural industrial structure where renewable energy power generation bases, animal husbandry bases, planting bases, and urban waste treatment bases gather at the same time, this paper proposed and established a rural energy complex(RMEC) topology and robust optimization model. First, considering the characteristics of the change in the amount of waste in the rural waste landfills around the city, a mathematical model for the centralized treatment of various types of waste was established. Next, an energy coordination model for energy supply, conversion, and storage of RMEC powered by renewable energy was established. Based on the adjustment needs of the external energy network, an energy supply response model for RMEC was established. Considering the uncertainty of the operation of the RMEC, a two-stage robust optimization model for the RMEC was established. The non-convex second-stage problem was transformed into a convex optimization problem through cone relaxation and dual transformation. Finally, the improved IEEE39-node power distribution system, 20-node gas distribution system and 14-node thermal system were used for simulation verification. The simulation results show that the RMEC can coordinate the relationship between renewable energy power generation, animal husbandry and garbage disposal and other industries, and can provide theoretical support for the rural revitalization, industrial restructuring and energy transformation of beautiful rural areas in the new era.
