Abstract

The aim of the paper is to generalize the matrix algorithm PFPD-3P in order to evaluate the three-phase power flow of real and large AC/DC transmission networks. It is shown that the HVDC-VSC/LCC links can be seen from the AC network busses as PV/PQ constraints, which represent both the AC and DC behaviour of the HVDC links. In HVDC-LCC link, an iterative procedure is exploited to estimate the reactive power request. Since three-phase power flow is fundamental to compute network power quality, converter sequence component behavior is considered for both VSC and LCC. In order to validate the method, solution comparisons with the commercial software DIgSILENT PowerFactoy are performed. Eventually, the voltage unbalance factors in a 76-busbar case study are computed.
