Assessment of the impacts of distributed generation and electric vehicles as mobile sources through a nodal and zonal pricing methodology

Abstract

Electricity is an essential asset for the economic and social development of any region. In the search for a cleaner, balanced and economical process, the industry and the electricity sector suffered several transformations over the years. Renewable energies became appealing, but electric vehicles also deserve attention, especially because they can act as source or load, with an impact on the electricity tariff. This work uses nodal and zonal pricing methodologies in a distribution system to verify the renewable micro-generation advantage to the system and to scale them through an electricity tariff system, based on a regulatory context implemented in Brazil. The used methodology enables one to assess how the distributed generators, including electric vehicles working as sources, interfere with the locational pricing in the system.
