Acesso em:.https://repositorio.ufpa.br/handle/2011/10098This dissertation addresses some of the major operational problems faced by distribution system operators due to the high integration of photovoltaic (PV) generators, such as overvoltages and excessive tap counts in step voltage regulators (SVR). These situations are continually being studied, since they can cause voltage quality problems and damage in SVRs. The overvoltage problem can be caused by a significant injection of active power from the PV generation to the network. Moreover, the rapid and significant variations in PV generator active power associated with cloud transients result in an increase of voltage regulator tap counts, which can affect the useful life of device. In this context, the smart inverters Volt-Watt and Volt-Var control functions have been added in recent studies to mitigate the overvoltages. This work shows how Volt-Watt and Volt-Var control functions mitigate the overvoltage and voltage regulation problems in distribution networks with PV generation. Time series power flow simulations on LV and MV single feeders with PV solar plant have been performed in high and low solar variability scenarios.Acesso AbertoInversor inteligenteSobretensõesComutações excessivas de tapeControle volt-wattControle volt-varRegulador de tensãoAlta penetração FVSistemas de distribuiçãoEnergia fotovoltaicaSmart inverterOvervoltageExcessive tap countsVolt-watt controlVolt-var controlVoltage regulatorHigh PV penetrationDistribution systemDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::GERACAO DA ENERGIA ELETRICASISTEMAS DE POTÊNCIASISTEMAS DE ENERGIA ELÉTRICA
