Abstract
This paper investigates two weighted least squares (WLS) approaches to the problem of load estimation (LE) in unbalanced power distribution networks: (1) the WLS load parameter method in is restated more rigorously; and (2) a constrained distribution state estimation (DSE)-based method is introduced to consider operating and loading constraints. Detailed simulation results on 394-bus radial and weakly meshed power distribution systems are evaluated through four error indices proposed by the authors previously (see Proc. IEEE Int. Symp. Circuits Syst., Pheonix, AZ, vol.5, p.697-700, 2002). The results of both methods are compared and discussed. Observability issues are also addressed.
