Energy policies are often related to the global effort in reducing greenhouse gas emissions through increased use of renewable energies in electricity production. The impact of these policies is usually calculated by energy planning tools. However, the modeling methodologies most currently used...

The increase of fossil fuel demand raises concerns on availability of resources for future energy demand and on potential environmental impacts. Electric vehicles (EVs) appear as one alternative to shift from fossil fuels to renewable energy resources. This research work analyzes the benefits of...

The design of transition pathways for sustainable electricity systems with high penetrations of renewable energy sources requires the use of energy modeling tools that are able to account for two key aspects: the evolution of fossil fuels and technology prices, and the natural dynamics of...

The European Union proposed the introduction of taxes on emitted CO2 as an effective policy measure for the reduction of CO2 emissions in its electricity sector. Applying the TIMES (The Integrated MARKAL-EFOM System) modeling tool, this paper examines the cost effectiveness of different...

The potential to reschedule part of the electricity demand in energy systems is seen as a significant opportunity to improve the efficiency of the systems, especially on remote and isolated systems. From the supply point of view, that flexibility might bring significant improvements to the...

Throughout the world, but mostly in developing countries, there are presently regions where electricity supply is insufficient or non-existing. Innumerous authors affirm that this lack of access to electricity is a key factor in perpetuating poverty around the world and compromises the...

This work analyzes different modeling methodologies for balancing the electricity supply sources and the electricity demand in systems with high penetration of intermittent renewable energy sources, such as wind and run-of-river hydro. This work also explores the reasons and the circumstances...
