摘要为充分协同利用输配电网资源并确保恢复方案的可行性,提出一种内嵌可行割约束的输配电网分布式交替优化供电恢复策略。首先,针对主变电站故障场景,构建输配电网协同供电恢复框架。其次,以最小化用户失电损失与系统供电成本为目标,建立输配电网各自独立的供电恢复模型及网络间的边界耦合约束。进而,基于分布式交替优化思想,通过内嵌边界传输功率的割平面约束,提出一种输配电网分布式协同供电恢复算法。最后,通过仿真算例验证了所提策略的有效性与准确性。结果表明,该策略能够协调输配电网两侧资源,为主变电站典型故障场景生成可靠的供电恢复方案,且其复电效果与集中优化方法相近。 To fully coordinate resources in transmission and distribution networks and ensure the feasibility of restoration plans,a distributed alternating optimization strategy for power supply restoration,embedded with feasible cut constraints,is proposed.First,a coordinated power supply restoration framework for transmission and distribution networks is constructed for fault scenarios in main substations.Second,aiming to minimize customer outage losses and system power supply costs,independent power supply restoration models for the transmission network and each distribution network are established,along with boundary coupling constraints between the networks.Furthermore,based on the concept of distributed alternating optimization and by incorporating cutting plane constraints for the boundary transfer power,a distributed collaborative power supply restoration algorithm for transmission and distribution networks is proposed.Finally,the effectiveness and accuracy of the proposed strategy are verified through simulation examples.The results indicate that this strategy can coordinate resources on both sides of the transmission and distribution networks,generate reliable power supply restoration plans for typical fault scenarios in main substations,and its restoration effectiveness is comparable to that of centralized optimization methods.
