Performance of multi-agent secondary control for reconnecting a microgrid of grid-forming converters to the main grid
Electrical microgrids (MGs) are meant to make access to electricity more flexible. In this regard, they are required to work, alternatively, either connected to or disconnected from (forming an island) the main grid. ... -
Slate–cork laminate enhanced with silicone for habitat industry application
(2024-05-01)This study investigates the feasibility of using a composite material comprising slate reinforced with cork sheets for architectural purposes like facades and wall coverings. The research involves the comprehensive ... -
A convergence control scheme for multi-stage holomorphic embedding load-flow method
(2024-05-16)Power flow analysis is a key tool for planning, operation, and control of power systems. The most novel family of power flow algorithms is based on the Holomorphic Embedding Load-flow Method (HELM), presented a decade ago. ... -
Unit commitment with analytical under-frequency load-shedding constraints for island power systems
(2024-12-31)This paper presents a novel corrective frequency-constrained unit commitment (C-FCUC) for island power systems implementing analytical constraints on underfrequency load shedding (UFLS). Since UFLS is inevitable for ... -
Regional socioeconomic assessments with a genetic algorithm: an application on income inequality across municipalities
(2024-06-01)Available data to depict socioeconomic realities are often scarce at the municipal level. Unlike recurring or continuous data, which are collected regularly or repeatedly, nonrecurrent data may be sporadic or irregular, ... -
Robust optimal design of UFLS schemes in Island Power Systems
(2024-09-01)Since settings of conventional underfrequency load shedding (UFLS) schemes cannot be adjusted in real-time, this paper proposes a novel robust optimal design method of the UFLS scheme for an island power system (IPS) that ... -
Electricity markets regulations: the financial impact of the global energy crisis
(2024-06-01)Amid the global energy crisis, we examine the impact of electricity market regulations in the European Union (EU). Pursuing an integrated EU electricity market inadvertently heightened the interdependence between gas and ... -
An exploratory study of fibre microplastics pollution in different process stages of salt production by solar evaporation in Spain
(2024-06-15)Microplastics are a pollutant of growing concern. Several studies have found microplastics in table salt worldwide in the last decade, although most have focused on already prepackaged salt. To the best of our knowledge, ... -
Application of ensemble machine learning techniques to the diagnosis of the combustion in a gas turbine
(2024-07-15)This paper describes a method based on the combination of several machine learning techniques, working together in an ensemble, with the aim of continuously monitoring the combustion of a gas turbine in a combined cycle ... -
Model-based energy planning: a methodology to choose and combine models to support policy decisions
(2024-08-01)Long-term energy planning is becoming increasingly reliant on mathematical models, which offer quantitative insight to support complex policy decisions. However, the increase in their use has meant the proliferation of ... -
Risk-averse electrolyser sizing in industrial parks: an efficient stochastic-robust approach
(2024-08-01)Hydrogen is called to be one of the most important energy vectors in future energy systems. Nowadays, its use in the industry sector is prominent, finding multiple applications in fertilizer production or oil refining. In ... -
Building and validating a large-scale combined transmission & distribution synthetic electricity system of Texas
(2024-08-01)Distributed energy resources, such as rooftop solar, have rapidly expanded in recent years, given declining costs and the desire to reduce carbon emissions. With more energy resources located in the lower-voltage distribution ... -
Energy management of a microgrid considering nonlinear losses in batteries through Deep Reinforcement Learning
(2024-08-15)The massive deployment of microgrids could play a significant role in achieving decarbonization of the electric sector amid the ongoing energy transition. The effective operation of these microgrids requires an Energy ... -
An optimal expansion planning of power systems considering cycle-based AC optimal power flow
(2024-09-01)This paper presents a novel mixed-integer linear optimization formulation of the AC network-constrained, cost-based, integrated expansion planning problem. The formulation is used to determine the investment needs per ... -
