The share of energy from renewable sources used in transport in the EU reached 9.6 % in 2022, up from 9.1% in 2021. Becoming the world''s first climate-neutral continent by 2050 is the objective behind the European Green Deal ( COM (2019
READ MORESince 2002, the penetration of non-hydro renewables in supply have increased from only 2 percent to 22 percent in 2012. The bulk of generation from new renewables, as in Portugal, is from wind energy.
READ MOREWith renewable energy penetration rate increasing [4], the system frequency stability will gradually deteriorate. This brings challenges to frequency stability and security which causes more attention to the analysis method of frequency stability [5]. To simplify frequency stability analysis, a second-order SFR model was applied in [6].
READ MOREThat is where renewable power comes in. Bulgaria''s solar generation already increased by a record amount in 2023, growing by 1.4 TWh (68%), more than double the growth in 2022 (+0.6 TWh, +42%). In 2023, Bulgaria also doubled the solar capacity, adding over 2 GW in 2023 alone and reaching 3.9 GW by the end of the year.
READ MOREBulgaria proposes a share of 25% of energy from renewable sources in gross final consumption of energy in 2030 as contribution to the EU renewable energy target for
READ MOREBulgaria is targeting a further 2,645 MW of installed electricity generation capacity from renewable sources, mostly photovoltaic plants, by the end of 2030, in line with the EU''s goals for green energy transition, a draft national strategy published on the parliament''s website shows. This additional capacity includes 2,174 MW of solar plants

READ MOREAbstract: This article examines the challenges and effects of integrating high levels of variable renewable energy (VRE) into conventional power systems, with a specific focus on the Bulgarian power system and market.
READ MOREIn conclusion, Bulgaria''s renewable energy transition followed a boom and bust cycle that was marked by a rapid expansion of renewable energy capacity until 2012, and subsequent policy adjustments that halted the development of new projects.
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 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
