Optimal management of a microgrid Li-Ion battery considering non-linear losses using the Integer Zig-Zag formulation
This paper presents a model for optimizing the management of a Li-Ion battery in a microgrid, considering the presence of nonlinear losses during the charging and discharging processes. The paper examines the nature of ... -
Risk adverse optimization on transmission expansion planning considering climate change and extreme weather events - the Texas case
The global push for environmental sustainability is driving substantial changes in power systems, prompting extensive grid upgrades. Policies and initiatives worldwide aim to reduce CO 2 emissions, with a focus on increasing ... -
Analysis of the Portuguese and Spanish NECPs using the CEVESA MIBEL market model
The member states of the European Union (EU) are actively reassessing their National Energy and Climate Plans (NECPs) [1] to jointly address climate challenges and the impacts of the COVID pandemic and gas supply crisis. ... -
Strategic plays in electricity markets: exploring gaming opportunities for demand under different settlement rules
Even when a market is cleared using optimal power flow calculations, ensuring dispatch feasibility, the settlement can be performed in different ways. In this paper, we consider three different types of settlement mechanisms ... -
Self-scheduling for a hydrogen-based virtual power plant in day-ahead energy and reserve electricity markets
This study presents an innovative optimization model for the self-scheduling of a hydrogen-based virtual power plant (H2-VPP) that aims to thrive in day-ahead energy and reserve markets. At its core, the model seeks to ... -
A comparative analysis of Cournot equilibrium and perfect competition models for electricity and hydrogen markets integration
The relationship between hydrogen and electricity has gained attention due to their interconnected roles in the energy transition. Existing joint electricity and hydrogen market models often overlook the dependence between ... -
Practical solutions to limit computational burden of UC in Island Power Systems
Unit commitment (UC) models used in real-life island power systems (IPSs) require complex modelling details and low execution times since they have to be launched repeated times for different assumptions and changing ... -
Equation with boundary feedback damping
In this paper we consider PDE problems in which certain terms of the equations are concentrated,when a parameter tends to zero. Usually near the domain boundary.This implies that the problem in question is subject to ... -
Measuring and mitigating biases in location-based recommender systems
This article is a summary of the work published in the journal Data Mining and Knowledge Discovery[1]. It presents an analysis of different types of biases and polarization measurements that affect the area of Point-Of-Interest ... -
Small-signal stability of type 4 wind generators as affected by the bandwidth of current and PLL controllers
This paper investigates the small-signal stability of type 4 wind generators as affected by the bandwidth of current and phase-locked loop (PLL) controllers. Using eigenvalue and participation factor analysis, this paper ... -
A reduced-order model for simulation of back-to- back start-up of synchronous motors in pumped storage hydropower plants
This paper proposes a reduced-order model for the simulation of back-to-back start-up of synchronous motors in pumped storage hydropower plants aimed at calculating the starting time of the generator-motor set. It is assumed ... -
On advancements and challenges in asset management for HVDC systems: a machine learning perspective
In the context of global climate goals and the transition to sustainable energy, modern energy transportation and distribution systems play a crucial role. Electricity transportation and distribution systems would not ... -
How a pandemic reshapes power patterns: a case study of electricity consumption in the Baltic countries during COVID-19
In addition to the enormous loss of life caused by COVID-19, the pandemic produced issues in various sectors such as industrial, economic, tourism, healthcare, etc. One of the sectors that is likely to have been affected ... -
