Analysis of Performance and Opportunity for Improvements in the Microgrid of Ilha Grande

Microgrids has emerged as an attractive solution to ensure electric power supply for remote locations, such as islands isolated from the continents. Sometimes, microgrids that have already been deployed need to be refurbished, either to keep up with the growing power demand or to replace end-of-life equipment. This paper reports the enhancement process that was carried out in a real microgrid system deployed in the northeast of Brazil. A comparative analysis of the microgrid operation performance is developed. The benefits of the refurbishment, both in terms of efficiency and power quality are also evaluated.
