The bulk of generation from new renewables, as in Portugal, is from wind energy. In 2011, wind energy contributed more than 15 percent of supply; solar more than 3 percent; and biomass nearly 2 percent.
READ MOREThe policies implemented to enable and accelerate the energy transition have impacted most sectors of the EU economies, directly or indirectly. The present study focuses on the impact of the increasing penetration of renewable energy sources (RES) in the energy mix as well as the energy market deregulation on the retail electricity prices for households.
READ MOREHybrid renewable energy systems, as the combination of different energy systems, provide a promising way to harvest maximum renewable energy. In the past decade, it has been a popular and rising topic in the research field. In this paper, the emerging application
READ MORESweden''s goal of 100% renewable electricity generation by 2040 requires investments in intermittent electricity production (e.g. wind power). However, increasing the share of intermittent electricity production presents challenges, including reduced flexibility of electricity production. A strategy for overcoming this issue is developing flexibility in
READ MOREEnvironmental concerns and technology development are driving power systems to a new stage where the increased penetration of renewable energy resources (RES) is replacing the conventional fossil fuel-based power plants. This transition brings the sustainable and ecological credentials but at the same time involves the major challenge of low-inertia
