Autossuficiência energética de um alimentador : uma percepção pela ótica de engenharia de energia

Abstract

About the global scenery, special in COP27, we need to extend our powers to content the wheater impacts. About this, with de assistance adopted by Brazil a few last years about the connection of energectic resources connected on distribution system. The distribuited energy resources (REDs) is growing up your importance of studies about factors that impact in operation of the Electrical Power System. In view of the expansion of the use of intermittant sources, like eolic and solar, this article has an objective to develop a methodologic procedure to analyse feeders of distribution system with a big presence of micro and mini Generation. In this contexto, using the Test Feeder IEEE 123 Bus, this work proposes to model and simulate using OpenDSS a Model Feeder so that it can operate in a state of energy self-sufficiency in the form of network blocks. The system was submitted to connection plots of photovoltaic systems of 300 kW each until the feeder reached a level where all the electricity consumed throughout the day came from the feeder itself. After this analysis, a new set of tests was carried out considering the dispatch from a storage source with a capacity of 20% of the installed power of each system, thus analyzing a new scenery of enregy self-sufficiency.
