Abstract

To analyze the suitable integrated energy system in rural areas, a multi time scale optimization method for rural multi regional integrated energy systems is proposed, considering the impact of system energy sources, energy storage settings, multi station collaboration mode, and grid connection distance on the rural integrated energy system. The results show that distributed energy systems in rural areas are more suitable for adopting a single station independent operation strategy. Multi time scale scheduling can improve system scheduling accuracy. In the scenario of not being connected to the grid, the total cost of renewable energy systems is 59.36% higher than that of fossil energy systems. In the scenario of grid connection, when the grid connection distance is 20 km, the economic efficiency of renewable energy systems is better than that of systems supplemented by fossil fuels, and the consumption rate of renewable energy is 62.5% higher than that of isolated operation. When the grid connection distance is greater than 40 km, the economy of the isolated operation system of the fossil energy supplementary supply is better, with a cost reduction of more than 10.15% compared to the renewable energy grid connection system. The selection of rural distributed energy systems should consider the distance between rural areas and the power grid.
