摘要

交直流混合拓扑已成为未来配电网应对多类型分布式电源(distributed generation，DG)和负荷高效并网的必然形态，如何实现交直流混合配电网的规划与求解成为一个亟待解决的问题。对此，该文提出一种基于非确定性关联场景聚类与线性约束的交直流混合配电网源网统一联合规划模型。考虑不同类型DG和负荷的相关性，建立多类型源荷的不确定性相关场景集，并通过改进的K-means算法对其进行场景聚类；提出包含网架结构和DG配置的交直流混合配电网统一表征方法，在此基础上构建系统的基尔霍夫统一潮流约束模型，并通过Big-M法对模型进行线性转化；最后，利用Gurobi求解器对以最优经济性为目标的交直流混合配电网源网统一联合规划模型进行求解。通过13节点配电网算例和区域互联配电网算例验证了所提规划模型的有效性和优越性。

Abstract

The hybrid AC/DC topologies have become inevitable for future distribution networks to efficiently deal with multiple types of distributed generations (DGs) and loads integrated into the grid. How to realize the planning and solution of hybrid AC/DC distribution networks has become an urgent problem. Therefore

an uncertain correlated scene clustering and linear constraints-based unified joint planning model for generations and networks of hybrid AC/DC distribution networks is proposed. The set of uncertainty- related scenarios for multiple types of DGs and loads is established by considering the correlation between different types of DGs and loads

and an improved K-means is used to achieve scene clustering. A unified characterization method including the grid structures and DG allocations is proposed for hybrid AC/DC distribution networks. On this basis

a unified Kirchhoff's power flow constraint model for the distribution network is constructed which is linearly transformed by the Big-M method. Finally

the Gurobi solver is used to solve the unified joint planning for DGs and networks of hybrid AC/DC distribution networks with the goal of optimal economy. The effectiveness and superiority of the proposed planning model has been verified on a 13-bus distribution network and an area-interconnected distribution network.
