Cooperative Planning Strategy of Rural Distribution Networks and Energy Storage

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 cooperative optimization planning method of rural distribution networks and energy storage is proposed considering the coordination of agricultural facilities in this work. 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 coordinated optimization planning model for rural distribution networks and energy storage is proposed, aiming to minimize the sum of investment and operating costs as the objective function, and an effective solution method is designed. Finally, an improved IEEE 33-bus system is employed as an example to verify the effectiveness of the proposed planning method.
