“…10. Based on the suitability index the buses can be ranked 12,15,11,13,14,8,10,9,7,16,6,2,3,4,5, 1, and 17. As per the previous case, the meter is placed based on the value of the suitability index.…”

This paper addresses the power quality (PQ) meter placement using a fuzzy expert system (FES). The meters are placed to make the system observable with minimum meters in the system. The PQ meters are placed using the suitability index.The suitability index is derived using FES has voltage and power loss index as input. Further, the importance of the voltage and power as input to the fuzzy system is also presented. The approach adopted is applied to the IEEE 9-bus radial distribution system and a ski area bus system. The minimum number of meters is determined at the suitable buses and results are discussed.

“…Porém, os autores propuseram a utilização de um algoritmo baseado em AG e conjuntos Fuzzy para a solução do problema de otimização, no sentido de dar mais flexibilidade à inclusão de novas restrições ao problema, como, por exemplo, na priorização de barras para a instalação de PQMs ou na restrição de barras onde já existem PQMs instalados. Para a simulação das faltas os autores utilizaram um simulador para redes elétricas chamado SINAP, ao invés de utilizarem a abordagem baseada em expressões analíticas (OLGUIN; VUINOVICH; BOLLEN, 2006;FARJAH, 2009;ESPINOSA-JUAREZ;HERNANDEZ;OLGUIN, 2009). Apesar de já considerarem faltas desequilibradas ocorrendo também ao longo das linhas, estas foram aplicadas em pontos discretos.…”

“…O trabalho apresentado em Haghbin, Farjah e Mazaherifar (2013) deu sequência à pesquisa iniciada em Haghbin e Farjah (2009). Por meio de um AG, os autores encontraram todas as soluções ótimas para o problema de otimização definido em Olguin, Vuinovich e Bollen (2006) e utilizaram três índices para ranquear as soluções.…”
