Um método de localização e dimensionamento ótimos de turbinas eólicas para minimizar as perdas de energia em sistemas radiais de distribuição.

Abstract

The distribution system has undergone changes over the years, mainly due to the increased insertion of distributed generation. With regard to wind energy, improper installation of wind turbines in a distribution system can result in increased losses and even in violation of voltage limits. In this context, a method for optimal location and dimensioning of wind turbines is presented here in order to reduce the losses of electricity in radial distribution systems. Were used the Genetic Algorithm as an optimization method and the Sum of Powers Method to perform the power flow calculations, not exceeding the voltage limits imposed by ANEEL, nor exceeding 20 % of penetration of wind generation regarding the annual energy demand. Six commercial models of wind turbines with different characteristics were located and sized in four test systems (36, 69, 134 and 1080 bars) in order to study the performance of the method. The results obtained demonstrated the effectiveness and viability of the method for use in small and large radial systems.
