Investigation on the Loss Allocation Properties in Distribution Networks with Distributed Generation

The allocation of the losses that occur during the operation of the distribution system to the distribution network nodes is useful to understand whether there could be a deficit or an excess of load or local generation in the nodes. This concept is extended in this paper by looking at the zones of the distribution network in which there is an interaction among the generations and loads. The sign of the allocated losses is considered as a useful indicator of the need to provide more load or more local generation in the zone. Specific findings are extracted from the analysis of balanced and unbalanced distribution systems with time-varying load and distributed generation.
