Abstract

AbstractThe distribution locational marginal price is an important congestion management method for the distribution network with a high proportion of distributed new energy. The refined formulation of the distribution locational marginal price is conducive to the allocate the electric energy economically and enhance the enthusiasm of both the generation side and the consumption side to participate in congestion management. Based on the linear optimal power flow model, a method for calculating the distribution locational marginal price by iteratively updating the loss factor is proposed. The price is divided into four parts: energy, loss, voltage and congestion. For a typical distribution network example, the proposed method is used to calculate the electricity price and different components of each node. The results show that the value and composition of the electricity price can reflect the actual operation of the system and solve the congestion.KeywordsDistribution locational marginal priceLinearized power flow modelDistribution network congestion managementLoss factor
