Abstract
This letter proposes an equality-constrained weighted least squares (WLS) state estimation model for networks containing LCC-HVDC links. Voltage and current phasor measurements for the AC network are provided by phasor measurement units (PMUs) and DC voltage and current measurements for the DC transmission lines are acquired by appropriate DC sensors. AC/DC coupling equations and zero injections are treated as equality constraints. Simulation results for a 6-bus hybrid AC/DC network are shown to validate the proposed model and algorithm.Keywords
