The need for changes in electric distribution network for the use of the mini and micro on grid generators

Abstract

It is expected that with the diversification of utilization rates, the increased demand for electricity and the difficulties encountered in hydroelectric generation, promote the acquisition of more renewable energy generators connected to the network. There's no way to keep a nationwide system of interconnected components and mini-generation connected to the network, effectively without the deployment of the smart grid. Through studies carried out in some inverters used in solar generators, it was verified the existence of harmonics that are injected in the distribution network, creating fluctuations of voltage and current. Rectification of the sine wave inverter, and the connection of multiple network generators cause oscillations in both voltage and frequency, making necessary a network that not only identify these fluctuations, but to interpret, going further, as should take measures to mitigate the effects of these oscillations. This requires an intelligent, interconnected network to the central data processing, intuitive and with a certain degree of autonomy, reducing response time to problems, directing and compensating voltage spikes and rectifying the quality of electricity injected by miscellaneous generators connected to the same.
