Metodologia para redistribuição das cargas entre as fases para regular a tensão no PAC de uma rede de distribuição de energia elétrica após a inserção de geração distribuída fotovoltaica.

Abstract

In this course conclusion work, a case study is carried out in order to prove the efficiency of the load redistribution between phases methodology to regulate the voltage at the Common Coupling Point (CCP) after insertion of Distributed Photovoltaic Generation (DPG). It was modeled, in OpenDSS software, an electrical energy distribution network with the presence of DPG, based on a real distribution network. The simulations of the modeled distribution network were carried out with and without the DPG and before and after the proposed correction of the voltage rise in CCP, in order to analyze whether the methodology of this work is an adequate method of voltage regulation in the CCP after insertion of DPG. From the simulations, it was verified that after the insertion of the DPG, there were 141 violations of the maximum voltage limit in the CCP required by ANEEL and these violations occurred in all months of the year. After applying the methodology based on the redistribution of loads between phases, 27 loads were relocated to the phase where the DPG was connected (phase 2), in wich 14 loads were removed from phase 1 and 13 loads were removed from phase 3, and all violations of the maximum voltage limit in the CCP were regulated. With the voltage regulation in the CCP, obtained from the redistribution of loads between phases, it is possible to guarantee greater safety for consumers and equipment installed in the distribution network in which the DPG is installed, as well as a reduction in costs with fines and repair of equipment damaged by the increase in the voltage in the CCP by the concessionaires
