Harmonics are among the serious problems that affect the power quality of an electrical system. However, harmonics nowadays are inevitable due to the ever-increasing number of Variable Frequency Drives (VFDs), Uninterruptible Power Supply (UPS) and other non-linear loads. In this regard, IEEE519 Standard specifies the allowable Total Harmonic Distortion (THD)...Read More

October 5th marks World Teachers Day', an opportunity to celebrate and thank teachers for their important role in our communities and for the positive impact they have on the lives of students. Teachers are so much more than meets the eye. In fact, students seldom take into consideration that outside...Read More

Nowadays, ever-increasing energy demands and the depletion of fossil fuels require efficient and environmentally friendly technologies for energy generation. In this context, energy systems integration makes for a very strong proposition since it results in energy saving, fuel diversification, and the supply of cleaner energy. To this end, it is...Read More

Biomass is one of the most versatile sustainable energy sources. This versatility allows utilization of different biomass feedstock using a verity of conversion techniques. Often, a biomass-to-bioenergy conversion method is selected depending on the application, end-use product, and the type of feedstock. In many applications such as residential energy supply,...Read More

The interconnection of wind power plants (WPPs) with distribution networks has posed many challenges concerned with voltage stability at the point of common coupling (PCC). In a distribution network connected WPP, the short-circuit ratio (SCR) and impedance angle ratio seen at PCC (X/RPCC) are the most important parameters, which affect...Read More

Energy generation and its utilization is bound to increase in the following years resulting in accelerating depletion of fossil fuels, and consequently, undeniable damages to our environment. Over the past decade, despite significant efforts in renewable energy realization and developments for electricity generation, carbon dioxide emissions have been increasing rapidly....Read More

Increasing capacity of interconnected wind farms to distribution networks significantly affects voltage stability because of wind farm limitation in regulating reactive power. Therefore, the main aspect in the design and planning of a distribution system connected wind farm is to analyse voltage stability at the Point of Common Coupling (PCC)....Read More

A lecturer and a postgraduate student from the Engineering Institute of Technology (EIT) recently virtually attended the 29th IEEE International Symposium on Industrial Electronics (ISIE2020) from the 17th to the 19th of July. ISIE focuses on advancements in knowledge, new methods, and technologies relevant to industrial electronics - along with...Read More

Throughout the world, Induction Generators (IGs) have been commonly used in numerous installations of Wind Power Plants (WPPs) due to their simple construction, low cost, etc. However, IGs are not capable of controlling reactive power and regulating terminal voltage. This adversely impacts voltage stability at the Point of Common Coupling...Read More

The use of underground cables is essential in power distribution networks as they mitigate the issues related to space availability and minimise line breakdown and increase system reliability. However, the detection and localization of cable fault is challenging due to the limited access to the cable burned under the ground....Read More

Wind Power Plants (WPPs) are generally located in remote areas with weak distribution connections. Hence, the value of Short Circuit Capacity (SCC), WPP size and the short circuit impedance angle ratio (X/R) are all very critical in the voltage stability of a distribution system connected WPP. This paper presents a...Read More

Harvesting energy from the wind as an alternative to fossil fuels has many advantages in terms of protecting the environment and promoting sustainability. However, the increasing penetration of wind power in electrical networks presents many challenges such as the intermittency of wind power, its relative high cost as compared to conventional sources, and...Read More
