Small scale simulation of lightning using vertical wires deployed by drones: on the land and sea peak current asymetry
(2022)
Conference report
Restricted access - publisher's policyIn this work we simulate lightning by means of vertical wires deployed by a multirotor drone under fair weather conditions. These wires, when isolated from ground, acquire an electric potential by virtue of electrostatic ... -
AC/DC systems interconnected by power converters: Modelling and practical aspects
(2021)
Conference report
Open AccessThe paper addresses the modelling of AC/DC systems interconnected by power converters. A non-linear model including three AC subsystems and two multiterminal DC systems interconnected by power converters are modelled in ... -
A fast power calculation algorithm for three-phase droop-controlled-inverters using combined SOGI filters and considering nonlinear loads
(2022-10-07)
Article
Open AccessThe power calculation is an indispensable element in droop-controlled inverters because the bandwidth of the measured power has a direct impact on the controller performance. This paper proposes a fast and accurate power ... -
Use of DSLR and sonic cameras to detect and locate high-voltage corona discharges
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-24)
Article
Open AccessCorona discharges are a concern in high-voltage applications. It is of utmost importance to detect and locate the discharges at an early stage using simple methods for this purpose. This paper evaluates and compares the ... -
Potential use of space-based lightning detection in electric power systems
(2022-12)
Article
Open AccessInformation about lightning activity and its parameters is necessary to design and evaluate the lightning protection of an electrical power system. This information can be obtained from ground-based lightning detection ... -
A systematic review of machine learning techniques related to local energy communities
(2022-12)
Article
Open AccessIn recent years, digitalisation has rendered machine learning a key tool for improving processes in several sectors, as in the case of electrical power systems. Machine learning algorithms are data-driven models based on ... -
Leveraging bi-directional EV charging for flexibility services in the distribution grid - the case of fever project
(2022)
Conference report
Open AccessDistribution System Operators face a challenging environment largely affected by the ever-growing integration of Distributed Energy Resources. Especially, Electric Vehicles have a rapidly growing presence in the distribution ... -
Using CMOS image sensors to determine the intensity of electrical discharges for aircraft applications
(Multidisciplinary Digital Publishing Institute, 2022-08-27)
Article
Open AccessThe development of more electric aircrafts (MEA) and all electric aircrafts (AEA) inevitably implies an increase in electric power and a consequent increase in distribution voltage levels. Increased operating voltages ... -
On-line core losses determination in ACSR conductors for DLR applications
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-04)
Article
Open AccessDynamic line rating (DLR) is a method that focuses on dynamically determining the maximum allowable current of power lines, while ensuring they operate within safe limits. DLR needs to monitor the temperature and current ... -
Impact analysis of energy-based control structures for grid-forming and grid-following MMC on power system dynamics based on eigenproperties indices
(2022-12)
Article
Restricted access - publisher's policyThis paper addresses the impact of the modular multilevel converter (MMC) energy control in the system dynamics when grid-forming and grid-following control schemes are used in the same system. The MMC total energy control ... -
A hybrid energy storage solution based on supercapacitors and batteries for the grid integration of utility scale photovoltaic plants
(Elsevier, 2022-07-01)
Article
Open AccessThis paper presents a 2-level controller managing a hybrid energy storage solution (HESS) for the grid integration of photovoltaic (PV) plants in distribution grids. The HESS is based on the interconnection of a lead-acid ... -
Feasibility assessment of industrial demand response
(2022-07-06)
Part of book or chapter of book
Restricted access - publisher's policyAs seen in this chapter, a cost-benefits analysis (CBA) is needed to measure IDR profitability. Such CBA should incorporate a LCC approach, which describe all cost involved in each stage of the IDR development cycle. ...
