We introduce a multimode resource-constrained project scheduling problem with finish-to-start precedence relations among project activities, considering renewable and nonrenewable resource costs. We assume that renewable resources are rented and are not available in all periods of time of the project. In other words, there is a mandated ready date as well as a due date for each renewable resour...

This study explores various scenarios and flexibility mechanisms to integrate high penetrations of renewable energy into the US (United States) power grid. A linear programming model e POWER (Power system Optimization With diverse Energy Resources) e is constructed and used to (1) quantify flexibility cost-benefits of geographic aggregation, renewable overgeneration, storage, and flexible elect...

Hybrid renewable power systems integrate two or more sources of energy, one of which is renewable, optionally a storage system and typically work in stand-alone mode. They are being considered more and more and we should increment their usage taking advantage of their positive benefits: free of charge resource availability, CO2 emissions reductions and subsidies. Dealing with their inconvenienc...

This paper investigates the potential of Romanian renewable energy across energy production and consumption definitions. Moreover, it presents a model that estimates the regional evolution of renewable energy diffusion, focusing primarily on hydro energy. Statistics showed that Romanian consumers have a key role in developing the renewable energy market, while it is also very important to ensur...

Apart from being vulnerable to the menace created by climate change, MENA countries consume more of non-renewable energy despite their resource endowments and great renewable potentials. Energy consumption, natural exploration urbanization may add environmental degradation since ecological distortions emanate human activities. This study investigates effects aforementioned variables on footprin...

As wave renewables can be a cornerstone in the energy mix framework necessary for green transition, new integrated model is introduced to assess coastal locations and resource potential renewable installations based on: (A) metrics indices, (B) geographical analyses. The Canary archipelago (Spain) relevant case study due its different islands' interactions human-related/environmental (including...
