It is also proposed an analysis of the influence, both negative and positive, caused by the control modes of these inverters in the stability of synchronous machine connected to the grid. Another proposed solution to be investigated in this work will be the use of the reactive power control mode of photovoltaic generators via the inverter, which can contribute to the relief of the reactive demand of distributed synchronous generators interconnected in the same electric system, in order to reduce the possibility of generating a voltage instability condition, after a big disturbance, or in the occurrence of contingencies in the electric power system that may affect weak or overloaded electrical grids and with large insertion of photovoltaic generators. The analysis of the control models will be carried out through simulations in the time domain, through the ANATEM and ANAREDE computational tools.Acesso AbertoEstabilidade de sistemas de potênciaGeração fotovoltaicaStability of power systemsPhotovoltaic generationDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::TRANSMISSAO DA ENERGIA ELETRICA, DISTRIBUICAO DA ENERGIA ELETRICASISTEMAS DE POTÊNCIASISTEMAS DE ENERGIA ELÉTRICA
