To enhance the resilience of the distribution power system network against hurricane events, quality proactive operational planning is required. The first action is to leverage the oncoming predicted hurricane events data for accurate proactive prediction of system line outage under hurricane events. In this article, a hybrid system line outage prediction method based on a statistical probabilisti...Show More
This paper presents the design of an optimal stand-alone hybrid renewable energy system (HRES) with storage for supplying medical facilities in sub-Saharan Africa, so that they have uninterrupted access to power while serving patients under critical conditions. The work has been motivated by the current Covid-19 pandemic which is plaguing the world and claiming lives. Two hospitals in Tanzania in ...Show More
In Thevenin impedance determination techniques, which are used for voltage stability assessment, approximations are common. The approximations produce erroneous results during critical operating times. This paper has solved the approximation problems and comes up with new Thevenin impedance determination technique suitable for online voltage stability assessment. The Technique is tested on a simpl...Show More
In this paper, an economic comparison was performed for a PV/wind hybrid microgrid system with different energy storage technologies designed for a health clinic located in a rural community of Eastern Cape province of South Africa. The main aim of the study is to understand the influence of different storage technologies (i.e. hydrogen, pumped hydro storage and lithium-ion battery storage technol...Show More
Development of renewable energy technologies has increased worldwide. Power systems, underneath intensely loaded situations, are at ultra-hazards of credible line outage and consequent voltage unreliability problem. Real power drop and voltage divergence minimization are measures of voltage security of power system grids. The work recommends the optimal usage of the SVC in the enhancement of the v...Show More
The use of internal combustion engine (ICE) vehicles over the years has contributed significantly to problems such as climate change, environmental pollution, and increased cost of gas. The automotive industry in South Africa is amongst the highest Carbon (CO2) emitters, responsible for approximately 20% of total emissions and the third highest contributor to air pollution. This has given rise to ...Show More
Untimely failures of Distributed Photovoltaic Power Generation System (D2PGS) Transformers has been reported by various utility owners in spite of designing in accordance to the technical criteria and practices of the existing technical standards during the design phase and manufactured units passing the Factory Acceptance Tests (FATs) to corroborate the newly manufactured and packaged D2PGS trans...Show More
The integration of classical transformer design procedures with the staggering speed and coherent versatility of modernistic computational methods to evaluate and manage stray losses in transformers incite better understanding into the transformer design philosophy especially for renewable energy (RE) application. This is on account of tools suchlike Finite Element Method (FEM) that can perform se...Show More
Photovoltaic (PV) systems are fast gaining a strong integration into today's distribution network. The distribution network was not initially designed to accommodate generation; hence this technology could lead to an increment in fault current, voltage swells, and distribution network unbalance. That notwithstanding, the increasing number of PV systems in the distribution network could benefit the...Show More
This paper reports on a load controller for a standalone wind power plant with storage. The controller incorporates a maximum power point tracking (MPPT) algorithm for always capturing maximum energy from wind flow. The load is modelled as a three-phase resistor and is interfaced with the variable speed wind turbine and permanent magnet synchronous generator (PMSG) through a diode bridge rectifier...Show More
This study investigated the feasibility of using a hybrid combination of solar, wind, and diesel generator to be connected with the existing electricity grid for some selected higher institutions in Nigeria. A model was developed to analyze the sustainability and efficiency of the hybrid energy system for Nigerian higher institutions. The selected locations for investigation were Afe Babalola Univ...Show More
This paper presents the design of an adaptive overcurrent protection scheme with a zonal approach for a standalone renewable-based microgrid with various generation capacity, generation type and loading conditions. Supply and loading conditions in the network are constantly monitored by a control system which in turn communicates with coordinated relays on each feeder in order to adapt to any chan...Show More
This paper presents the design of a cost-effective stand-alone electricity generation system with a storage option for Dedelo farming community in the Eastern Cape province in South Africa using plant biomass feedstock. Average load for the community is estimated to be 338.88 kW with a peak load of 1 510 kW and average energy consumption of 8 133 kWh/day, respectively. A plant-based biomass resour...Show More
The majority of faults on electric power systems are traceable to distribution networks due to the exposure of the networks to different adverse climatic conditions, among other factors. Power outages due to climatic factors are inevitable since a major part of a distribution network is made up of overhead lines and exposed to different unfavorable weather conditions. Climatic factors need to be f...Show More
Load forecasting is the estimation of future electric load based on historical electric load data and it is important in power system expansion planning and management. To economically and reliably operate the grid, a power utility company requires accurate demand forecasting models. Therefore, developing and refining the existing forecasting models in the field of load forecasting is an interesti...Show More
In modern power systems, emerging load centers have led to a significant increase in electricity demand thus straining power utilities. Better economics of operation, reliability of power supply and the utilization of old power plants as power reserves during peak loads are some of the advantages of the interconnected systems. Power availability is also a key factor in industrial site location hen...Show More
Voltage stability analysis provides an assessment of the weak, unstable or uncontrollable sections of the power system network that may pose a risk for future load growth due to unexpected voltage collapse. Different methods of determining susceptible buses have been demonstrated over the decades, with V-Q curves being used to determine the critical point and stable operating region of a particula...Show More
The paper presents a cost-effective design of off-grid hybrid renewable energy system by hybridizing local renewable resources with diesel generator and battery storage for a remote and completely unelectrified rural village in South Africa. The system sensitivity analysis was performed by looking at two major sensitive parameters (diesel price and wind speed). Two rural villages based in differen...Show More
In recent times, sustainable development has received so much media, business and government attention, sometimes influencing the decisions of both voters and end-users. Expectedly, several organizations and governments endeavor to demonstrate their sensitivity to this theme in order to earn favors. Electrifying rural households falls within the topics on the front-burner. Although the general con...Show More
The increased integration of decentralized renewable energies in distribution networks has brought different challenges in the analysis and planning of electrical networks. The network manager must have appropriate tools allowing rapid decision-making and fair invoicing of consumers or remuneration of producers. In this article, we introduce a novel approach based on the famous Ising's model in or...Show More
This paper deals with the performance analysis of 10hp induction motor using finite element analysis (FEA) approach. The motor has been tested at different loading conditions at temperature of 75 degree. The loadings under analysis were: the rate load, intermittent loading, and multi-intermittent loading of 50%, 100%, 200%, and 300% of 52.7Nm rated load. It was found that the performance of the mo...Show More
