摘要：

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 [3] 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 in [15]. The results of both methods are compared and discussed. Observability issues are also addressed.
