Distribuição de Recursos Energéticos para Análise dos Impactos da Geração Distribuída

Abstract

The increasing penetration of Distributed Energy Resources (DERs) and Distributed Generation (DG) means a paradigm change in planning and operation of power systems around the world. In order to understand and circumvent the possible challenges arising from the growing energy injection at this grid level, new modeling and analysis tools are required. This paper presents a methodology for the distribution of energy resources for power system analysis. In this method, the feeder is divided into regions and probabilities of DG occurrence are determined for each of the delimited zones. The energy resources are allocated in a random and iterative fashion, according to the established application goals, described through boundary conditions. In terms of results, the method presented the capability to estimate the occurence of load shifting, losses reduction, and changes on voltage fluctuations once the integration of DER increases. The procedure proved to be flexible and efficient in the development of case study scenarios and it may be applied, among others, in the analysis of DER penetration impacts’, hosting capacity studies.
