摘要
Power electronic converters are the key power conversion equipment in modern AC-DC hybrid distribution networks. Their reliable design and control, especially its optimized operation, should be adopted to ensure the reliability of its long-term operation. Based on the flexible controllability of the converter, this paper proposes an optimal power flow calculation for the AC-DC hybrid distribution network considering the converter power constraints and DC voltage constraints. First, a power flow calculation model is established for the power electronic converters and AC-DC hybrid distribution networks. Secondly, an optimization strategy for hierarchical power sharing is proposed, and an optimal power flow objective function considering reliability constraints is constructed. Finally, the optimal solution of the decision variables is calculated based on the JAYA algorithm. In this process, a Jacobian matrix processing method is proposed to improve the speed of power flow calculation as well as the efficiency of the algorithm. The results of calculation examples show that the method can well solve the optimal power flow problem of the AC-DC hybrid distribution network with two ends, multiple ends, or multiple feeders considering its long-term operation reliability. © 2021, Power System Technology Press.
