The high dependence on fossil fuel is one of the main reasons for the difficulties experienced in the electricity sector in Cape Verde. According to forecasts the electricity demand will double by 2020, reaching 670 GWh, with this raise on electricity consumption and none other Renewable Energy projects than the ones currently underway, the fossil fuels consumption will continue to increase. Given the high levels of renewable penetration to be installed between 2015 and 2020, and in order to ensure that the exploration of the parks does not jeopardize the continuity and quality of service, it has become indispensable to carry out impact studies on the electricity network.
The overall objective of the “Grid capacity and stability studies in Sal island” project was to study the capacity and stability of the grid existing in Sal island (Cape Verde).
The development of this study includes the description of the electricity networks, the consumption and conventional generation scenarios, the injected renewable power values and a detailed analysis of the network voltage profiles in each scenario, as well as the analysis of the power transits in each branch of the network in order to obtain overloads and possible reinforcement needs.
