Microgrids provide a good platform to improve the efficiency of distribution networks. This platform, which is owned by the private sector, needs coordination with the distribution network owner in order to carry out its mission in the fields of operation and expansion planning. The distribution network expansion decisions are influenced by the expansion of microgrids. Therefore, the main issue that needs to be addressed is how expansion decisions interact with distribution networks and microgrids. This paper proposes a new framework for studying the interactions between resources and lines expansion in microgrids, and distribution network expansion. The proposed model is designed as a bi-level optimization problem. In the upper-level, with the aim of maximizing the profit of the microgrid owner, optimal decisions on distributed resources (location and sizes) and lines expansion are adopted. The lower-level problem involves the distribution network problem, in which, with the aim of minimizing the expansion and operation costs, energy exchanged with the microgrid and the upstream network, and the lines expansion of distribution network, are determined. Due to the non-convexity of both the upper and lower-level problems, a combination of evolutionary and mathematical algorithms is used to solve the proposed model. The study results on the IEEE 33-bus network using proposed framework show that the presence of a microgrid structure in the distribution network expansion planning helps to improve operation conditions and encourage investor participation in the power system.

微电网扩容策略与配网扩容规划交互框架开发

微电网为提高配电网络的效率提供了一个良好的平台。该平台为私营部门所有,需要与分销网络所有者协调,以执行其在运营和扩展规划领域的使命。配电网扩展决策受微电网扩展的影响。因此,需要解决的主要问题是扩张决策如何与配电网络和微电网相互作用。本文提出了一个新的框架来研究微电网中资源和线路扩展以及配电网络扩展之间的相互作用。所提出的模型被设计为一个双层优化问题。在上层,以微电网所有者利益最大化为目标,采用了关于分布式资源(位置和规模)和线路扩展的最佳决策。下层问题涉及配电网问题,以最小化扩展和运行成本为目标,确定与微电网和上游网络的能量交换,以及配电网的线路扩展。由于上层和下层问题的非凸性,本文采用进化算法和数学算法相结合的方法求解该模型。使用建议框架对 IEEE 33 总线网络的研究结果表明,微电网结构在配电网扩展规划中的存在有助于改善运行条件并鼓励投资者参与电力系统。下层问题涉及配电网问题,以最小化扩展和运行成本为目标,确定与微电网和上游网络的能量交换,以及配电网的线路扩展。由于上层和下层问题的非凸性,本文采用进化算法和数学算法相结合的方法求解该模型。使用建议框架对 IEEE 33 总线网络的研究结果表明,微电网结构在配电网扩展规划中的存在有助于改善运行条件并鼓励投资者参与电力系统。下层问题涉及配电网问题,以最小化扩展和运行成本为目标,确定与微电网和上游网络的能量交换,以及配电网的线路扩展。由于上层和下层问题的非凸性,本文采用进化算法和数学算法相结合的方法求解该模型。使用建议框架对 IEEE 33 总线网络的研究结果表明,微电网结构在配电网扩展规划中的存在有助于改善运行条件并鼓励投资者参与电力系统。确定与微电网和上游网络的能量交换,以及配电网络的线路扩展。由于上层和下层问题的非凸性,本文采用进化算法和数学算法相结合的方法求解该模型。使用建议框架对 IEEE 33 总线网络的研究结果表明,微电网结构在配电网扩展规划中的存在有助于改善运行条件并鼓励投资者参与电力系统。确定与微电网和上游网络的能量交换,以及配电网络的线路扩展。由于上层和下层问题的非凸性,本文采用进化算法和数学算法相结合的方法求解该模型。使用建议框架对 IEEE 33 总线网络的研究结果表明,微电网结构在配电网扩展规划中的存在有助于改善运行条件并鼓励投资者参与电力系统。
