Solutions to mitigate power quality disturbances resulting from integrating intermittent renewable energy in the grid of Porto Santo

Abstract

Due to the electricity increase consumption in recent decades, the rising price of fossil energy and uncertainty associated with its supply, there has been a growing concern for energy efficiency and the exploration of endogenous renewable energy sources. These changes are intended to promote greater security in supply, to reduce energy bills as well as greenhouse gas emissions. If this effort make sense anywhere, it is even more significant in islands where conventional primary energy is considerably more expensive. Given the intermittence of renewable sources such as solar and wind, it becomes essential to search for effective solutions to integrate them into the grid. This work describes the methodology for choosing an effective solution for the integration of intermittent generation in the island of Porto Santo.
