Advances in Theoretical and Computational Energy Optimization Processes
The paradigm in the design of all human activity that requires energy for its development must change from the past. We must change the processes of product manufacturing and functional services. This is necessary in order to mitigate the ecological footprint of man on the Earth, which cannot be considered as a resource with infinite capacities. To do this, every single process must be analyzed and modified, with the aim of decarbonising each production sector. This collection of articles has been assembled to provide ideas and new broad-spectrum contributions for these purposes

The Impact of Incorporating Wind Energy in the Electric Grid
In this paper we investigate the impact of increasing the penetration of wind generation with real variability on the risk to, and robustness of, the power transmission grid using a dynamic model of the power transmission system (OPA). There are three timescales of variability discussed but this paper will focus on the impact of two. It is found that with different fractions and distributions of wind generation and central generation, varied dynamics and risk are possible. One important parameter is the fraction of the total power demand supplied by the wind generation. It is found that the risk has a minimum in fraction of wind power supplied, after which the risk increased as the wind power penetration increases. In the same networks, decreasing the number of central generators without decreasing their power supplied in general increases the risk after a critical minimum number of generators is reached

Grid flexibility by electrifying energy systems for sustainable aviation
This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonDecarbonisation of aviation goals set by Flightpath 2050 Europe’s Vision for Aviation
requires that the airports become emission-free by 2050. This thesis original contribution to
knowledge is to explore the incorporation of aviation electrification technologies, including
electric aircraft (EA), electrified ground support equipment (GSE), and airport parking electric
vehicles (EVs), into power systems, evaluating their influence on grid infrastructure and
operations, as well as their potential to support the grid operation.
A comprehensive review of aviation electrification technologies revealed a research gap in the
integration of these technologies into the power systems. The thesis contributes to electricity
network infrastructure planning for electrification of aviation and airport-based distributed
energy resources (DER) that provide ancillary services to the power grid.
A multi-objective airport microgrid planning framework is developed, comparing EA charging
strategies and revealing that battery swap performs better. Vehicle-to-grid (V2G) strategy with
parking EVs improves the microgrid's performance. A techno-economic assessment of wireless charging
systems for electric airport shuttle buses shows better economic performance than conventional
buses and other charging options.
A novel Aviation-to-Grid (A2G) flexibility concept provides frequency response services to the GB
power system using EA battery charging systems, with typical A2G service capacity showing
significant variation across eight UK airports. A deep reinforcement learning (DRL)-based A2G
dispatch approach evaluates the impact of EA charger capacity on energy dispatch results, with
higher capacities leading to higher revenue and lower operation costs.
To summarise, this thesis addresses the research gaps in integrating aviation
electrification technologies into power systems, offering valuable insights for airport operators
aiming to decarbonise air transport activities through the adoption of these technologies. The
study also provides an understanding of the impacts on grid operators in terms of infrastructure
planning and operations. This comprehensive approach ensures a cohesive understanding of the
challenges and opportunities presented by aviation
electrification and its integration into power systems
Power System Simulation, Control and Optimization
This Special Issue “Power System Simulation, Control and Optimization” offers valuable insights into the most recent research developments in these topics. The analysis, operation, and control of power systems are increasingly complex tasks that require advanced simulation models to analyze and control the effects of transformations concerning electricity grids today: Massive integration of renewable energies, progressive implementation of electric vehicles, development of intelligent networks, and progressive evolution of the applications of artificial intelligence
A review on the complementarity of renewable energy sources: concept, metrics, application and future research directions
It is expected, and regionally observed, that energy demand will soon be
covered by a widespread deployment of renewable energy sources. However, the
weather and climate driven energy sources are characterized by a significant
spatial and temporal variability. One of the commonly mentioned solutions to
overcome the mismatch between demand and supply provided by renewable
generation is a hybridization of two or more energy sources in a single power
station (like wind-solar, solar-hydro or solar-wind-hydro). The operation of
hybrid energy sources is based on the complementary nature of renewable
sources. Considering the growing importance of such systems and increasing
number of research activities in this area this paper presents a comprehensive
review of studies which investigated, analyzed, quantified and utilized the
effect of temporal, spatial and spatio-temporal complementarity between
renewable energy sources. The review starts with a brief overview of available
research papers, formulates detailed definition of major concepts, summarizes
current research directions and ends with prospective future research
activities. The review provides a chronological and spatial information with
regard to the studies on the complementarity concept.Comment: 34 pages 7 figures 3 table
