Abstract: How to efficiently accommodate scaled distributed resources and ensure the security and reliability of power systems is a major issue that the construction of rural distribution networks must face in the current and future periods. In this background, a distributionally robust cooperative optimization planning method of rural distribution networks and energy storage is proposed considering the coordination of agricultural facilities. First, the characteristics of agricultural loads are analyzed and mathematical models of agricultural greenhouse loads, agricultural irrigation loads and agricultural production loads are built. Then, a cooperative planning model of rural distribution networks and energy storage is proposed to minimize the sum of investment cost and operation cost, taking the agricultural facilities into account. In order to effectively deal with the uncertainty of the generation outputs of the PV, a distributionally robust optimization model for cooperative planning of rural distribution networks and energy storage is proposed, and a solution method based on the column and constraint generation(C&CG) algorithm is proposed. Finally, an improved IEEE 33-bus system is employed as an example to verify the effectiveness of the proposed planning method. Simulation results show that the coordinated planning of the distribution network and the energy storage can help reduce investment and operating costs. The distributed robust optimization method proposed can balance the economic efficiency and robustness of the planning scheme.
