Evolução diferencial híbrida com programação quadrática aplicada ao problema de despacho econômico de energia elétrica

Abstract

Neste artigo propõe-se uma nova metodologia híbrida para resolução do problema de despacho econômico de energia elétrica com o efeito do ponto de válvula. O método híbrido proposto integra evolução diferencial (ED) com a técnica de programação quadrática seqüencial (SQP). A ED é utilizada como otimizador global e a SQP é utilizada para o ajuste fino da otimização, realizada pela ED. A metodologia híbrida e suas variantes são validadas para sistemas teste de 3, 13 e 40 unidades geradoras térmicas com funções incrementais de custo de combustível que levam em consideração o efeito de carregamento devido ao ponto de válvula. O método híbrido proposto supera e providencia soluções promissoras, em termos de eficiência, se comparadas com as obtidas pela ED e SQP sozinhas bem como de outras técnicas propostas na literatura para o problema de despacho econômico de carga com o efeito do ponto de válvula.
