This paper presents a new approach based on Genetic Algorithm (GA) for the solution of Optimal Reactive Power Flow (ORPF) in multiterminal ac-dc systems. Active power loss optimization is implemented through GA considering the constraints of entire multi-terminal ac-dc system. Ac-dc power flow is solved by sequential method. So, any ac and dc power flow algorithm can be used effectively in the proposed approach. Unlike the similar studies, active powers of all converters except at least one are selected as control variables for ORPF in this study to achieve most suitable converter active powers and converter types that improve active power loss minimization.This paper presents the first study that utilizes GA for the solution of optimal reactive power flow in multi-terminal ac-dc systems in the literature. The proposed approach is tested on the modified IEEE 14-bus ac-dc test system. The obtained results by this study and another alternative study are also given. Comparative results showed that the proposed approach is more efficient and reliable in reaching to a global optimum while satisfying entire system constraints.

W artykule przedstawiono propozycję metody zarządzania rozpływem mocy biernej w sieci AC-DC, opartej na algorytmie genetycznym. Optymalizacja strat mocy czynnej została dokonana przez uwzględnienie w algorytmie ograniczeń w całym systemie AC-DC. Proponowane rozwiązanie jest pierwszym tego typu podejściem do optymalizacji rozpływu mocy biernej w wieloterminalowej sieci. Testy wykonane zostały na zmodyfikowanym 14-szynowym systemie w standardzie IEEE. Analiza porównawcza z innymi rozwiązaniami wskazuje, na większą skuteczność i niezawodność przedstawionej metody.
