“…Using these average daily energy budgets estimated by VIC-Res, GridPath-SAPP determines the hourly dispatch for each reservoir within a maximum limit (determined by the rated capacity) and a minimum limit (assumed to be 30% of the average daily energy budget), ensuring maximum generation for each day does not exceed the daily energy budget. The design specifications of existing and planned reservoirs were retrieved from global reservoir and dam databases 59,62 , and complemented by basin-specific studies on Zambezi 63 , Congo 64 , Cunene 65 , Kwanza 66 , Rufiji 67 , and Orange 68 . For more details on the hydropower power potential characterization methodology and validation, see 26 .…”

The scale at which low-carbon electricity will need to be deployed to meet economic growth, electrification, and climate goals in Africa is unprecedented, yet the potential land use and freshwater impacts from this massive build-out of energy infrastructure is poorly understood. In this study, we characterize low-impact onshore wind, solar photovoltaics, and hydropower potential in Southern Africa and identify the cost-optimal mix of electricity generation technologies under different sets of socio-environmental land use and freshwater constraints and carbon targets. We find substantial wind and solar potential after applying land use protections, but about 40% of planned or proposed hydropower projects face socio-environmental conflicts. Applying land and freshwater protections results in more wind, solar, and battery capacity and less hydropower capacity compared to scenarios without protections. While a carbon target favors hydropower, the amount of cost-competitively selected hydropower is at most 45% of planned or proposed hydropower capacity in any scenario—and is only 25% under socio-environmental protections. Achieving both carbon targets and socio-environmental protections results in system cost increases of 3-6%. In the absence of land and freshwater protections, environmental and social impacts from new hydropower development could be significant.

“…To set up VIC-Res, we used the global flow direction map 57 with the same spatial resolution of VIC. The design specifications of existing and planned reservoirs are retrieved from global reservoir and dam databases, 58,59 and complemented by basin-specific studies on Zambezi, 60 Congo, 61 Cunene, 62 Kwanza, 63 Rufiji, 64 and Orange. 65 We simulated daily streamflow and daily hydropower budget for the 1997-2016 period (Figure S13).…”

“…The creation of mega centers of power generation on the basis of renewable energy sources, for example, large-scale hydropower plants -HPP ("Three Gorges" HPP on the Cháng Jiāng River in China, a large HPP on the Congo River in Central Africa and others) and mega parks of windmills in the North Sea and on the Arctic coast of Russia, solar power plants in the Sahara and Gobi Deserts, and others, is a relatively new factor [14,15]. Figure 2 gives an example of a mega project of West European Electric Power Interconnection development on the basis of wind turbines in the North Sea and solar power plants in the Sahara Desert [16].…”

The paper deals with the main prospects and challenges of radical transformations of electric power systems (EPSs) with changes in their structure and properties conditioned by wide use of innovative energy-related technologies and digitalization and intellectualization of system operation and control. Structural trends of EPS development are the focus of the analysis. Consideration is given to changes in EPS properties driven by the use of new technologies, to the problems of system flexibility and to its enhancement. EPS “resiliency” and “survivability” notions are subjected to comparison. The main factors favoring the formation of future EPSs to cyber-physical systems are discussed. Objective trends of EPS control and protection system development are under consideration.
