摘要

提出了一种明确考虑保护系统约束的径向配电系统优化重构方法。提出了一种基于图分析的全自动化方法来自动识别不同网络拓扑下各保护设备对之间的主备关系。据此，自动导出保护系统约束，并将其纳入优化问题。采用二阶锥规划（SOCP）对线性化和凸化的非线性潮流方程以及保护系统的协调约束进行求解，保证了结果的可行性，同时加快了收敛速度。通过33节点IEEE测试系统的仿真验证了该方法的有效性。

Optimized Distribution Systems Reconfiguration Considering Protection Devices Constraints

This paper presents a method for the optimized reconfiguration of radial distribution systems that explicitly considers the protection systems constraints. A fully automated method based on graph analysis is proposed to automatically identify the primary-backup relation between each pair of protection devices in different network topologies. Accordingly, protection systems constraints are derived automatically and incorporated into the optimization problem. The linearized and convexified nonlinear power flow equations, along with protection system coordination constraints, are solved using the second-order cone programming (SOCP) that assures the feasibility of the results while accelerating the convergence rate. The effectiveness of the proposed methodology is demonstrated through the simulation of the 33-node IEEE test system.
