摘要:
针对多分布式电源优化调度中存在的计算量与通信量大、难以实现整体完全分布式调控等问题,结合调频控制对一致性算法进行改进,提出一种基于超节点协同一致性算法的源-荷协同调度方法。首先,基于单跳采样法对原分布式电源网络结构进行拓扑重构,选取超节点并对决策变量进行求解,划分的局部集内的普通节点只与超节点进行通信;其次,对离散型一致性算法进行改进,提出一种自适应全局修正系数的调频控制方法,通过采集系统频率偏差大小决策全局修正系数参与功率调节,来更好地适应主动配电网实时调度和完全分布式控制,并用所提控制方法求解系统运行成本最小调度模型;最后,通过MATLAB仿真验证所提调度方法在应对拓扑切换和源荷突变场景下的有效性。仿真结果表明:在系统发生突变时,所提调度算法能够实现一致性增量成本的快速收敛,并有效控制各分布式电源的增量成本在8.95元以下;在系统无突变情况下,算法仅需197次迭代便可实现调度分配,可主动为调度部门提供了一种有效的方案。
Abstract:
To solve the issues of high computational and communication costs, as well as the difficulty in achieving fully distributed control within multi-distributed power generation optimization scheduling, a source load collaborative scheduling method based on the supernode collaborative consistency algorithm was proposed in this study, which combined frequency modulation control to enhance the consistency algorithm. Firstly, the original distributed power network structure′s topology was reconstructed based on the single-hop sampling method. Super nodes were chosen for solving of the decision variables, while the local set of ordinary nodes within the partition only communicated with these supernodes. Secondly, an adaptive global correction coefficient frequency modulation control method for improving the discrete consistency algorithm was introduced to better adapt to real-time scheduling and fully distributed control of active distribution networks. This method was utilized to address the system′s minimum operating cost optimization scheduling model. Finally, the effectiveness of the proposed scheduling method in dealing with topology switching and source load mutation scenarios was verified through MATLAB simulation. The simulation results showed that rapid convergence of consistency incremental cost could be achieved by the suggested scheduling algorithm, effectively controlling each DG′s incremental cost below 8.95 yuan when the system underwent sudden changes. Without sudden changes in the system, 197 iterations were needed by the algorithm to achieve scheduling allocation, offering an effective solution for the scheduling department.
