不同黑启动方案下电网重构效率的评估
Investigation on the Efficiencies of Power System Reconfiguration with Different Black-start Schemes
【摘要】 不同黑启动方案对系统后续恢复的影响不同,因此在黑启动方案评估时,除了考虑各方案本身技术指标的优劣,还应考虑此方案对系统后续网络重构的影响。文中对不同黑启动方案下电网重构效率的问题进行研究,提出一种综合考虑发电容量恢复和系统停电损失的重构效率指标,结合最短路径法与交叉粒子群算法对不同黑启动方案下网络重构过程中的机组出力和负荷恢复进行优化求解。在IEEE30节点系统和河北南网中应用的计算结果验证了该方法的有效性。
【Abstract】 Because the different black-start schemes have different influences on the subsequent network-reconfiguration process,in assessment of the black-start schemes,the influences of the schemes on the subsequent network-reconfiguration should be considered,in addition to the technical verifying indexes of the feasible schemes to be selected.In this paper,the efficiencies of power system reconfiguration with different black-start schemes are investigated.A network-reconfiguration efficiency index to consider generation capacities and outage costs of the important loads is proposed as the target of the reconfiguration optimization.The Dijkstra algorithm and the cross PSO algorithm are employed to optimize unit generation output and the load restoration in the network-reconfiguration process.The numerical results on the IEEE 30 bus system and the southern power network of Hebei Province verify the effectiveness of the proposed method.
