Resumo

In areas with access to the power distribution system, Photovoltaic Generators introduced to the electrical network appear as the viable economic and socio-environmental option for the generation of electrical energy. In contrast, this new scenario arises bringing impacts and new challenges to the distribution system. For example, violation of voltage levels at the connection points that can occur by the injection of active power. The main objective of this work is to analyze an electrical system with photovoltaic solar generator, and transient states. It is achieved an steady-state through simulations with the Newton-Raphson and Power Summation methods implemented in Matlab, for transient state, circuit simulations in PowerSim. In order to study the effects of the addition of a photovoltaic generator in the energy distribution system, data from a real network was used for better applicability of the results. Part of the IEEE 30-bus system was selected with some adjustments: use of the first 6 buses, generator connection on bus 5, exclusion of interconnection between buses 2 and 4. The results show that addition of photovoltaic generators can be an important part of a solution to the problem of voltage drop at the of the distribution network. (AU)
