Classification of power quality disturbances using advanced deep learning algorithms for Accurate and efficient electrical signal analysis
Abstract: Power systems today have to deal with more and more power quality issues (PQDs) like voltage drops, rises, harmonics, and transients because more people are using renewable energy sources and electronic devices. These problems can hurt equipment, stop services, and lower the overall reliability of power. In real-time settings, traditional detection methods often don't work as quickly or accurately as they should. This paper looks at how deep learning models, …

Development of dynamic model for alkaline water electrolyser: Application to disturbance analysis
Abstract: A dynamic model of an alkaline water electrolyser plant has been developed to study its time dependent behaviour when it is subjected to dynamically varying inputs like changing electrolyte flow, inlet temperature, pressure, current, voltage. Such dynamic conditions are expected to arise during start up and shut down and also when the electrolyser is coupled to a nuclear or renewable electricity source, both of which exhibit time dependent power output …

Enhancing Weak Grid Stability Using Grid-Forming BESS in Renewable-Dominated Power Systems
Abstract: The growing share of renewable energy sources in the energy mix, particularly photovoltaic (PV) installations, has resulted in the reduced grid inertia and system strength, thus presenting new challenges in terms of voltage and frequency stability in weak grid situations. Conventional grid-following (GFL) inverters rely on synchronizing with the grid and performing relatively poorly under specific situations such as disturbances, voltage sags, or islanding. It has been the aim of …

Rural electrification through micro-grid design case study
Abstract: We introduce the design and experimental demonstration of a scalable DC micro-grid for rural electrification in the developing regions. The distributed control of the grid voltage is one of the main features of the DC micro-grid architecture, which allows both instantaneous power sharing and a metric for available grid power. A droop-voltage power-sharing scheme is utilized wherein the bus voltage decreases in response to low supply/high demand. Besides that, the …

Quality of sleep among post menopausal women
Abstract: Background: Menopause is a time of major hormonal, physical and psychological change for women. Sleep disturbances are very common in menopausal women. Sleep disturbances among menopausal women have been ascribed to a number of factors e.g., normal physiological changes associated with aging, poor health perception, menopausal-related symptoms, nervousness, stress, mood symptoms (e.g. depression and anxiety), and co morbid chronic health issues. Besides these biological and chronobiological factors, socioeconomic, psychosocial, cultural, …
