Grid Study on the Basis of Reciprocal Power Losses Calculation
Abstract
It was found that the losses of some supplierconsumer pairs in a grid (reciprocal losses) can be negative. Upon exploring this issue, it turned out that this phenomenon is not rare and is a result of a certain distribution of the power of electricity suppliers between consumers. Negative reciprocal losses indicate that the overall grid losses are increased. They can be eliminated by redistributing the suppliers’ power. Computing the reciprocal losses, additional properties of a power system can be defined, which facilitates the determination of its more economical operation mode.
