Electrical Engineers and the Infinity in Power Systems

In the realm of power systems, infinity serves as a pivotal theoretical construct, facilitating the representation of extreme limits of quantities as they approach exceedingly large values. This theoretical framework simplifies complex problems and fosters creative problem-solving approaches for engineers. This paper explores the multifaceted role of infinity as a theoretical construct in power systems scenarios, showcasing how this abstraction harmonizes with the practical application of eng...

Integration of FDIR Practices in Distribution Optimal Network Reconfiguration Routines

The adoption of optimal network reconfiguration (ONR) tools is crucial in enhancing the operational efficiency, security and reliability of smart distribution grids, since ONR can be used to ensure grid integrity and quality of supply among end-users. However, in order to improve ONR applicability in a SCADA/DMS framework, the actual practices in fault detection, isolation, and recovery (FDIR) must be taken into account. For this reason, this paper proposes a ONR formulation, based on Mixed-I...

Control of a PV-Electrolyzer-Fuel Cell Microgrid for the Provision of Grid Services in Distribution Systems

Stationary applications of hydrogen-based tech-nologies, such as electrolyzers and fuel cells, constitute new resources in the pathway towards energy transition. However, nowadays, normative and grid codes still lack technical specifications concerning the adoption of hydrogen technologies in power networks. On this regard, this paper proposes a monitoring and control architecture designed with the scope of advancing the practices in the exploitation of hydrogen-based flexible resources. In c...

Adaptive Scheme for Stability Margin Estimation of Grid-Connected DFIG Based Wind Turbines

With the increasing adoption of wind power into the grid, ensuring the reliable protection of wind farm generators against grid faults has emerged as a crucial concern. Instability, as a consequence of severe disturbances, poses a significant threat, capable of inflicting damage to network equipment. In the Doubly-Fed Induction Generator (DFIG), one of the most-used technologies in wind farms, activation of the crowbar circuit results in the blocking of the power converter and control system....

Distributed Adaptive Droop Control Method for Flexibility Enhancement of Islanded DC Microgrids Including Electric Springs

DC Microgrids (DC-MGs) are gaining attention as they pave the way for merging various means of energy resources with DC outputs. In the context of islanded DC-MGs, the intermittent nature of renewable energy resources and the uncertainty in demand profiles across various timescales pose prominent challenges for ensuring continuous power supply. To overcome this concern, a combination of generation units and energy storage systems are conventionally employed. However, in this paper, the storag...
