Harmonic analysis of distributed generation in Smart City Búzios project

The commercial and industrial sectors have come up against paradigm changes that concern the need for improving their activities, in order to develop processes with less environmental impact, sustainable and energy-efficient, aiming at reducing energy consumption. Technologies based on renewable sources for power generation, such as solar and wind, have emerged as an alternative for these sectors. With the development of distributed generation technologies, such as photovoltaic cells, wind turbines, and so on, it is necessary to identify and classify the disturbances that embedded electronic systems in these technologies may cause on distributed grids. This paper presents some data collected and analyzed on the Smart City Búzios project, where were installed three small wind turbines and solar photovoltaic systems in different grid points. This work presents and discusses some data collected on these systems regarding harmonic analysis. In the remaining of this paper is discussed data related to: vertical wind turbines, photovoltaic system for charging electric vehicles, photovoltaic system feeding computerized command center and photovoltaic system powering LED lamps in public area.
