Electricity is an essential public service for economic and social development of any country. To meet specific consumer requirements, such as quality and fair price, the Electric Power Industry suffered a large improvement process in many countries, which imposes challenges to agents who work in it, among which is a form of compensation of new investments in the distribution network. In this sense, the present work shows the application of a method based on nodal prices to send economic signals to users in distribution systems. The method consists of two elements. P-I calculates the price on the used capacity element of the network, to reflect the use of the circuit, and P-II calculates the price for the unused capacity of a network element, based on the Lung Run Incremental Cost (LRIC) in order to reflect the impact on the advancement or deferral of future investment in network components as a result of an injection or withdrawal of generation or load at each study node. The main objective is send signal prices to connect Distributed Energy Resource (RED) at certain points of the distribution network. The methodology is applied to the IEEE 13 nodes radial distribution test feeders, analysis of the behavior of nodal prices for various scenarios of loading and entering load/generation in the system being made.
