“…(secondary) radial distribution networks. Therefore, an optimal procedure for harmonic analysis in distribution systems should be based on one of the following: (1) a three‐phase radial load flow for unbalanced conditions (Equation is a multiphase node equation system); (2) a radial load flow for balanced conditions . Both procedures, which are based on the network structures of distribution systems, current‐injection formulation, and Kirchhoff's law, are solved by the simple forward/backward sweep technique.…”

“…Because of the relatively low power of photovoltaic (PV) systems, they are generally connected to distribution systems. The coupling of PV systems to such networks is a source of problems for network operation [1][2][3][4][5][6][7][8] and protection [9] because of the presence of PV harmonic currents. Therefore, the analysis of the problems generated by PV harmonic currents in distribution systems and their resolution has become an increasingly important concern for utilities.…”

“…Gosbell e Ghezelayagh (1992) desenvolveram o programa Power Eletronic Simulator (PES) para análise em domínio do tempo de harmônicos em sistemas de distribuição e utilizaram a ferramenta para avaliar as interações entre fontes de harmônicos e componentes do sistema. Nesta mesma linha de desenvolvimento de algoritmos computacionais Tostes e Bezerra et al (2004) utilizaram o método de soma de correntes para modelar sistemas com fluxo harmônico trifásico, com introdução de barramentos específicos para sistemas fotovoltaicos para facilidade de utilização em sistemas com geração distribuída. Para validação do modelo, foi simulado um sistema real localizado em Belém -PA, com 92 transformadores de diferentes capacidades e cargas de diferentes tipos e um total de 216 barras.…”

“…Para realizar o cálculo de correntes e tensões harmônicas, primeiro obtém-se o estado básico da rede elétrica (frequência fundamental) com o fluxo de carga trifásico apresentado no Capítulo 5 e na sequência, com base nas referências (Archundia, 2010;Tostes, 2004e Teng, 2007 procede-se da seguinte forma:…”
