Alteração nas correntes de curto-circuito com elevada integração de geração distribuída fotovoltaica

Abstract

With the advancement of technology, lower prices and low environmental impacts, the use of photovoltaic generators is becoming increasingly viable, studying the effects of the high integration of photovoltaic generators in the electrical system, on short-circuit currents, for example, they will indicate that the electrical system will need to prepare to avoid or mitigate such effects. One of the most used and efficient ways to analyze the effects caused by the massive insertion of photovoltaic generators is to carry out studies in computer simulators, such as OpenDSS and Pycharm software, which mathematically simulate circuits, calculate short-circuit currents and automate and the insertion of photovoltaic generators in different scenarios. With this variety of data and scenarios generated, the behavior of the studied systems is very close to reality. In this study, the single-phase and three-phase short-circuit currents were analyzed, verifying the greatest variation during the insertion of photovoltaic distributed generation in the points of the system which have loads. The photovoltaic generators will be inserted in different ways and the short circuit currents will be calculated at each insertion.
