Abstract
Currently, the nine islands of the Autonomous Region of the Azores have fossil fuel power stations as their main source of electric power. Each island has an independent electrical system classified as an isolated micro-system, given its size and location. The goal of this study is to analyze the best set of technologies for a sustainable hybrid system. This study will be applied first on São Miguel to make the largest island of the archipelago 100% renewable. We will consider factors such as the island’s actual data production, economic scenarios, growth perspectives of consumption and reliability of supply.
Highlights
On a worldwide level, there are many initiatives available to increase the utilization rate of renewable energies on islands, thereby reducing their dependence on fossil fuels and allowing their transformation towards more sustainable energy systems
The problem of confirming and predicting the effect of energy savings is subject to data on energy consumption volumes, climate data, geo-information and socio-economic conditions, among others [2]
It is possible to form predictive functions of energy consumption and make better choices concerning the renewable sources to be used in the design of each micro-net
Summary
There are many initiatives available to increase the utilization rate of renewable energies on islands, thereby reducing their dependence on fossil fuels and allowing their transformation towards more sustainable energy systems. The problem of confirming and predicting the effect of energy savings is subject to data on energy consumption volumes, climate data, geo-information and socio-economic conditions, among others [2]. With these data, it is possible to form predictive functions of energy consumption and make better choices concerning the renewable sources to be used in the design of each micro-net. To establish a sustainable hybrid system is a good solution for isolated islands like the Azores, because, in addition to allowing lower energy costs, such a system avoids the requirement of transporting fuels to the islands This transport is sometimes complicated given the distance, adverse conditions of the sea, or even the ports themselves, though mainly by the costs associated with the operation
