Power flow, FACTS, MTDC


This article proposes a novel and robust algorithm, called improved sequential method, for the power flow solution in a power system embedded with MTDC (Multi-Terminal DC) links and FACTS (Flexible AC Transmission System) devices. General injected power models of FACTS devices and MTDC links are developed and incorporated into the new algorithm. The proposed method exhibits good convergence characteristics and ability to be implemented in conventional AC power flow programs. The effectiveness of the proposed algorithm is demonstrated, and the results are compared with the other two conventional methods, simultaneous Newton-type algorithm and sequential method.
