Grid Forming Inverters: EPRI Tutorial (2021)
Abstract With the increasing penetration of renewable energy, inverter-based resources (IBRs) are gradually replacing synchronous generators as the new generation capacity. As present
The electrification of Angola through network extension may include up to to 93% of the population, 100% of municipalities and 70% of communes (about 391). The majority of the provinces with the exception of Cunene, Uíge and Malange, would obtain a grid connection rate of around 90%, as shown
on the graphic in figure 14 and 7% of the Angolan population, which represents 2% of demand, could be electrified via decentralized systems, such as small hydros, photovoltaic systems or conventional diesel generation. iii) ELECTRIFICATION MODELS
The electrification strategy that supports the vision Angola Energy 2025 was based on criteria of economic rationality and territorial balance in order to ensure optimal allocation of financial resources and, at the same time, the balanced development of the country together with the reduction of regional asymmetries.
Due to the high concentration of the Angolan population in the capital, other provincial capitals and municipal townships, in all the models presented it will be possible to reach the 60% goal through a concentration of the electrification effort in urban areas, including more or less municipalities depending on the model chosen.
The Balanced or Economy-based model is the one that best meets the aspirations of the Angola 2025 Strategy, by promoting a more balanced model of territorial development and optimizing the overall electrification costs, including operating costs.
Overall, only 7% of the population of Angola will be supplied by decentralized generation, representing only 2% of potential domestic demand. On the other hand, about 9,000 consumption sites representing 93% of the Angolan population and 98% of demand may be electrified by grid extension.
