摘要:

随着分布式电源的规模化接入,传统配电网故障恢复策略逐渐难以适应实际需要。为此,提出一种含分布式电源的配电网故障紧急恢复与抢修协调优化策略。首先,在故障紧急恢复模型中引入典型负荷时变性需求模型,优先恢复需求度高的负荷。以抢修时间最短和社会经济损失最小为综合目标函数得到故障抢修模型。然后,研究故障紧急恢复与抢修协调优化策略,利用主网与孤岛协调控制进行故障恢复,通过改进粒子群算法得到最优抢修顺序。在抢修过程中,考虑负荷及时变性需求变化,调整故障紧急恢复与抢修最优方案,保证配电网可靠、快速恢复正常运行状态。最后,通过算例仿真验证了所提策略的有效性。

Abstract:

With the large-scale access of distributed generators, the strategy of the traditional distribution network fault recovery is gradually difficult to adapt to the actual needs. Therefore, the coordinated optimization strategy of fault emergency recovery and repair for distribution networks with distributed generators is proposed. Firstly, the typical load time-varying demand model is introduced into the fault emergency recovery model to restore the load with high demand first, and the fault repair model is obtained by taking the shortest time and the minimum social and economic loss of distribution network restoration as the objective function. Then, the coordinated optimization strategy of fault emergency recovery and repair is researched. The main network and island coordination control are used for recovery and the improved particle swarm optimization algorithm is used to obtain the optimal repair sequence. In the emergency repair process, considering the changes of load and time-varying demand, the optimal scheme of emergency recovery and repair is adjusted to ensure that the distribution network is reliable and quickly restored to normal operation. Finally, the IEEE 33-bus system is used for example analysis, and the results verify the effectiveness of the proposed strategy.
