Changes are currently unfolding within electric distribution networks as renewable energy integration grows. This paper introduces a novel stochastic approach for expansion planning in distribution networks with high renewable energy penetration. The model addresses uncertainties, daily and seasonal impacts, distributed generation remuneration, car...

The energy resource management problem in energy systems is hard to optimize, mainly due to non-linear restrictions and a large number of variables involved. This is partly because of the increased integration of distributed energy resources. Computational intelligence optimization techniques, namely evolutionary algorithms, are regarded as efficie...

With the current state of the electrical power system, regarding the increase of renewable generation integration and electric vehicle penetration to reduce gas emissions, the energy resource management problem becomes extremely complex to optimize to the significant dimensionality and uncertainty. Metaheuristic optimization algorithms become effic...

We propose the concept of “explainergy”, a new way of including explainability in the metaheuristic performance of algorithms solving problems in the energy domain. To this end, we open the discussion around eXplainable computational Intelligence (XCI), focusing on using metaheuristic optimization for complex energy-related problems. It is well kno...

Hydrogen is a promising commodity, a renewable secondary energy source, and feedstock alike, to meet greenhouse gas emissions targets and promote economic decarbonization. A common goal pursued by many countries, the hydrogen economy receives a blending of public and private capital. After European Green Deal, state members created national policie...

Due to the rising concern for the environment and sustainability issues, the transportation system is experiencing important changes to its paradigm, with the increasing replacement of internal combustion vehicles by electric ones. Consequently, the electric systems need to adapt to the ever-increasing load demand from the grid and the challenge to...

Energy resource management is a concept that should be considered in energy systems due to the significant penetration of dispersed energy resources. Thus, the efficiency in the electrical network operation can be improved and the end-user costs reduced. In this way, an energy resource aggregator plays an important role in managing the demand and g...

Demand response (DR) programs and local markets (LM) are two suitable technologies to mitigate the high penetration of distributed energy resources (DER) that is vastly increasing even during the current pandemic in the world. It is intended to improve operation by incorporating such mechanisms in the energy resource management problem while mitiga...

The energy resource management (ERM) problem in today’s energy systems is complex and challenging due to the increasing penetration of distributed energy resources with uncertain behavior. Despite the improvement of forecasting tools, and the development of strategies to deal with this uncertainty (for instance, considering Monte Carlo simulation t...

Due to the fast growth of energy consumption in buildings, it is crucial to ensure sustainability demands through the use of renewable energies. The solar energies have been standing out and, as a result, the forecast of photovoltaic (PV) production has received broad attention. However, the intermittent nature of the generated power brings some un...

The electrical sector has been evolving. This situation is because new methodologies emerge to deal with the high penetration of distributed energy resources (DER), mainly electric vehicles (EVs). In this case, energy resource management has become increasingly prominent due to the technological advances that are taking place, mainly in the context...

Due to the increasing electricity consumption in the residential sector, new control systems emerged to control the demand side. Some techniques have been developed, such as shaping the curve’s load peaks by planning and shifting the electricity demand for household appliances. This paper presents a comparative analysis for the energy consumption o...

Given the current state of the society in which we live, in terms of energy pollution, several objectives have been set to try to reduce environmental problems. Some of these goals include an exponential increase in production through renewable energy, and Electric Vehicles (EVs) circulating on roads. Due to this high penetration of distributed ene...

Every year, the number of electric vehicles (EVs) on the roads has been increasing on a large scale. The electric grid, in this case, must evolve with the high penetration of distributed energy resources such as EVs and renewable energies. Indeed, demand response (DR) programs and the flexibility of EVs can help to mitigate the challenges of the in...
