READ MOREIn other words, higher penetration of renewable energies has more influence on reliability indices than on vulnerability indices of power systems. Therefore, mechanisms must be implemented to increase the response capacity of infrastructures with a high proportion of renewable energies against n-1 or n-2 contingencies.
READ MOREAlthough renewable energy use constitutes a significant portion of the electricity generation globally, this transformation requires increased use of renewables higher than the existing share. In 2015, the United Nations declared "the deployment of renewable energy" as one of the sustainable development goals (Singh et al., 2019 ).
READ MOREWind and solar energy depend on seasonal weather conditions to generate energy, such as wind and radiation, respectively. However, few studies have focused on analyzing and measuring the impact of a progressive increase of renewable energy in a short-term electricity market and its effect on energy security.
