Analysis of fractional resonant controllers for voltage-controlled applications
(Multidisciplinary Digital Publishing Institute, 2024-11-07)
Article
Open AccessThis paper investigates the application of fractional proportional–resonant controllers within the voltage control loop of grid-forming inverters. The use of such controllers introduces an additional degree of freedom, ... -
Optimal power flow with regression-based small-signal stability constraints
(Institute of Electrical and Electronics Engineers (IEEE), 2024-01-01)
Article
Open AccessIn modern power systems, with a growing integration of inverter-based resources, small-signal stability is becoming increasingly important. However, current practice in operation and planning studies is based on solving ... -
Itinerary-dependent degradation analysis of a Lithium-Ion battery cell for E-Bike applications in Rwanda
(2024-10-21)
Article
Open AccessThere are obstacles to the widespread use of small electric vehicles (EVs) in Rwanda, including concerns regarding the battery range and lifespan. Lithium-ion batteries (LIBs) play an important role in EVs. However, their ... -
Enhancing grid stability: a frequency regulation control strategy for BESS in grid-connected
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessControl and protection mechanisms in grid-connected microgrids (MGs) can pose significant challenges due to the frequency fluctuations arising from variations in load demand or the intermittent nature of renewable energy ... -
Controlled and safe hydrogen generation from waste aluminum and water, a new approach to hydrogen generation
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-11-30)
Article
Open AccessA new method is proposed to generate hydrogen in situ at low pressure from powder-pressed recycled aluminum turnings activated with small amounts of NaOH and drops of water. The contribution of this system is that the user ... -
Investigation of GLM detections of negative continuing currents observed by high-speed video and narrow-band 777 nm photometer
(Elsevier, 2025-02)
Article
Open AccessLightning flashes with continuing currents are characterized by high energy transfer to ground that produces severe damage to electric power systems. Novel space-based optical lightning detection systems offer new possibilities ... -
Sensitivity analysis of corona discharges measuring instruments using different electrodes and high voltage supplies
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Article
Open AccessCorona discharge testing is critical to ensuring the safety, performance and reliability of high-voltage equipment and systems. Due to the high cost of shielded laboratories, many manufacturers test their components in ... -
Partial inertial support for PV MPPT systems connected to grid using the IPLL control strategy
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Restricted access - publisher's policyReduction of inertia from conventional generation is rising questions towards grid-operators about the reliability of generations in the upcoming years. The loss of synchronous generators in addition to the massive increase ... -
Analysis of the relationship between light intensity and electrical power of corona discharges
(2024-11-20)
Article
Restricted access - publisher's policyThis work analyzes the intensity of the light emitted by corona discharges using a smartphone camera, which is compared to the electrical power associated with the corona discharges. The raw images from the camera provide ... -
Multi-physics operation and sizing optimisation in Pyomo: application to large irrigation systems
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Conference report
Open AccessThe use of flexibility in the form of demand response, storage, or power flow control is a desirable feature for modern electricity distribution systems where uncertainty is a major concern. In this respect, we focus on ... -
