摘要 主动配电网中将分布式电源作为可控可调度机组参与最优潮流运行调度,而现有的方法很难协调优化计算的精度和效率,为此提出一种适合大规模配网,具有较高计算精度的含可调度分布式电源优化算法,即通过优化少环网的连枝上串联理想电压源和网络的近似等效变换,在满足配网辐射状约束的条件下,实现了重构,电容器优化投切和可调度分布式电源出力三者的同时高效优化.算例结果验证了算法的准确性,快速性和对大规模配网的适应性.

Abstract:The distributed generators(DGs) are regarded as the dispatched generators participating in Optimal Power Flow(OPF) in active distribution networks. But the conventional algorithms could not coordinate the precision and efficiency. This paper proposes an efficient and high calculation precision joint optimal algorithm with dispatched DGs. The proposed algorithm implements the reconfiguration, capacitor switching and output of the dispatched DG joint optimization by the optimization of imaginary ideal voltage sources that in series with link branch and approximate equivalent conversion of networks. At the same time the radial constrains are satisfied. The different size of test systems were performed showing the efficiency and precision of the proposed algorithm.
