increasing the integration of Renewable Energy Sources (RES), such as wind, solar, geothermal, hydro, ocean and biomass. In the same direction, the European Union has set targets for specific levels of RES integration in the future European energy mix, with progressive participation of 20% in 2020, [28] 32% in 2030 and two-thirds in 2050. [24,25,27] These goals are to be achieved considering the participation of all Member States, which are defining their own policies and goals to match the general targets. For instance, Spain has established a target of 42% of RES share on energy end-use by 2030. [74] Germany and France defined a target of 65% and 40% of RES in the final electricity consumption, respectively. [26] In order to achieve the aforementioned targets, realistic power systems models are required, considering a variety of technologies, system topologies, and elements such as high-voltage direct current (HVDC), [78] microgrids, [34] virtual power plants, and dynamic virtual power plants. [53] Various future scenarios are being analyzed for each system and region to ensure that the future energy systems, composed mostly of RES, can remain stable, reliable, match the demand during the seasonal variations across the year, and are economically feasible. These studies are regional by nature as they consider local weather and the availability of resources. Some examples were conducted for provinces or regions, such as Ontario, [55] British Columbia, [63] the New York State, [51] among others. [7,13,31,46] Similar studies have also been performed using data from countries, such as Australia, [15] Bangladesh, [33] Brazil, [72,14] Chile, [54] France, [47] Germany, [66] India, [4] Italy, Pakistan, [71] Portugal, [65,30] United Arab Emirates, [3] and the United States. [52] Other studies have also analyzed systems with an ambitious goal of 100% of RES. [36,50,58,62,81] Moreover, as the number of studies has largely increased, several tools have been proposed to assist the generation expansion planning and RES design, such as EnergyPLAN, [22] EnergyScopeTD, [49] HOMER, [37] LEAP, [75] SILVER, [55] TIMES, [39] among others. [11] However, most of these studies focus on renewable resources while keeping the electrical grid out of their analysis. The contrary is also true for the grids, as several power system benchmarks have been proposed without a clear rationale for the resource type and location in the grid. A few examples are the IEEE and the CIGRE benchmarks. [64] As the power systems are adapting to support a massive integration of RES, both the resources and the Recent environmental policies have led academic, industrial, and governmental stakeholders to plan scenarios with a high share of renewable energy sources (RES), to ensure that future energy systems, composed mostly of RES, can remain stable, match the demand during seasonal variations and are economically feasible. This article considers different energy scenarios to obtain various options in terms of size, generation technologies, and grid configuratio...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
