A New Active Power Loss Allocation Method for Radial Distribution Networks with DGs

In this paper, a new active power loss allocation (LA) scheme is developed by eliminating the influence of cross-term mathematically from loss equation for allocating losses to the network participants with/without distributed generators (DGs). The unique bus identification scheme introduced performs load flow easily and efficiently by considering DGs as negative constant power loads. This method assigns losses to the consumers/DG units with due consideration to their power consumptions/injections and physical locations in the radial distribution network (RDN). The effectiveness of the proposed LA scheme has been investigated against the quadratic scheme of LA using a 33-bus RDN with/without DGs.
