However, an adequate analysis of the interaction with the alternating current (AC) network during network disturbance, especially during inter-area power (IAP) oscillations is needed. Insufficient damping of oscillations can significantly impact the reliability and effective operation of a whole power system. Therefore, this paper focuses on the stability of the modified Kundur two-area four-machine (MKTAFM) system. A robust secondary controller is proposed and implemented on a line commutated converter (LCC)-based multi-terminal high voltage direct current (MTDC) system. The solution consists of a local generator controller and the LCC MTDC (LMTDC) system, voltage-dependent current order limiter, and extinction angle controller. The proposed robust con...

It has been established that many rural locations in Sub-Saharan Africa away from the grid connection have difficulty accessing electricity. The inaccessibility of reliable energy and essential medical equipment was the leading barrier to improved healthcare delivery in these rural locations. The deficiency of basic medical equipment to power essential services due to limited or unreliable electricity access has reduced rural healthcare workers’ care capabilities, resulting in higher mortality rates. This paper, therefore, reviews the existing energy solutions for rural healthcare facilities, thereby analysing different approaches and the geographical energy mix and ascertaining the effectiveness of various techniques and energy mix as solutions to effective healthcare delivery in healthcare centres. Hybrid Renewable Energy Sources (HRES) microsystems, like microgrids incorporated with sol...

These include driver scheduling, which, in many cases, is still being done manually; diversion of vehicles to unauthorized routes by drivers for selfish reasons results in illegal use of fuel meant for official duties, causing the organization lose considerable revenue. In its drive to reduce its carbon footprint, Elizade University, Nigeria, is embarking on the development and use of electric vehicles (EV) as a means of transportation within the university campus. This research is geared towards supporting this initiative by developing an EV tracking system that combines tracking of EV drivers with vehicle position and battery power (energy) tracking in order to mitigate the challenges outlined above. Personnel tracking was achieved using an RFID-enabled staff identity card that authenticates authorized drivers before activating the vehicle ignition system, position tracki...

However, its sustainability in terms of efficiency is very important for the growth of every country. This main objective of the paper is to assess the productivity dynamics of this process using the data envelopment analysis (DEA) methodology to analyse the effectiveness of the electricity distribution regions (EDRs) over a period of 7 years. The paper adapts the biennial Malmquist productivity index by infusing it with the slacks-based measure (SBM) to assess the productivity dynamics of EDRs in Ghana. Productivity dynamics were assessed by decomposing the SBM-BMPI productivity scores into the efficiency, technology, and scale change. It was discovered that the productivity of EDRs in Ghana progressed by 16.23% per annum over the sample period. Productivity was driven mainly by technological change and not the efficiency changes and scale changes.

This could be due to challenges such as gender discrimination, gender stereotype, socio-cultural limitations, employment discrimination, and sexual harassment, to mention, but a few. This challenges and many more have limited the level of participation and retention of women in engineering in most countries. Therefore, there is need to address these challenges nationally, regionally, continentally and globally so that more female young career seekers can pursue a career in any engineering field of their choice, and those in the career can be retained in the profession until retirement. This paper presents the challenges women are facing in engineering profession. Furthermore, opportunities and recommendations are presented that can help to improve the participation and retention of women in engineering until retirement.

The nexus of energy poverty and gender is at play in the affected communities, as women and girls are culturally stereotyped with the task of collecting unclean fuels (e.g., firewood) and using these for their households’ energy demands. Therefore, this study prioritized rural women and girls as respondents in the provinces most affected by gendered energy poverty (GEP) in the country. The study was carried out in selected rural unelectrified areas of Limpopo, Mpumalanga, and KwaZulu-Natal provinces using structured interviews. The study revealed that GEP in the rural areas has exposed women and girls living there to security concerns, health hazards, premature death, domestic fire accidents, time poverty, income poverty, illiteracy, drudgery in households and farm tasks, etc., at different levels of severity.

A grid-connected smart microgrid comprising heterogeneous (active and passive) smart consumers and a large-scale energy storage device is considered in this work. Energy management by each smart entity is carried out by the proposed Microgrid Energy Management – Distributed Optimisation Algorithm (MEM-DOA) installed within the network according to consumer type. Each smart consumer optimises its energy consumption, expenditure and trading for comfort and profit. The proposed model was observed to yield financial benefits, grid reliability and sustainability, reduced investment on peaker plants, reduced Peak-to-Average-Ratio (PAR) demand and associated environmental benefits.

This study investigates the costs of microgrid solutions in comparison to grid extension to provide universal electricity access in Ntabankulu Local Municipality, Eastern Cape, South Africa. The Hybrid Optimization Model for Electric Renewable (HOMER) software was used to carry out simulation, optimization and sensitivity analyses. The results showed that a Wind/Diesel Generator/Battery-powered microgrid has the lowest cost with a breakeven grid extension distance of -45.38 km. The proposed microgrid could supply electricity at $0.320/kWh, with 0.0057 kg/kWh CO2 emissions and 90.5% renewable fraction, which are lower than grid extension. Therefore, a Renewable Energy Source (RES) hybrid microgrid solution can be a viable option for electrifying far-from-the-grid unelectrified areas of the Eastern Cape.

The Rand West Municipality is a community that has a slow-paced rural electrification and is subject to multiple power cuts weekly thereby affecting the households, farms, and businesses in the area. It is therefore taken as a case study for the investigation of a Renewable Energy Sources (RES) microgrid. Simulation, optimization, and sensitivity analyses were conducted to determine the feasibility and optimal RES mix for the location using the Hybrid Optimization Model for Electric Renewable (HOMER) software. The simulations yielded an optimal microgrid system consisting of a combination of Solar Photovoltaic (PV) panels, Solar Concentrated Photovoltaic system, Battery Energy Storage System and a Diesel Generator with a Cost of Energy (COE) of $0.068/kWh, compared to the grid COE of $0.12/kWh for this area.

Laptop is an essential electronic appliance for individuals, schools and businesses, which you can't afford to be down on power. Remote areas are often challenged by consistent interrupted power supply, thereby delaying or hindering certain work that needs to be done with laptops. Hence, off-grid solar energy solutions is proposed to charge laptop batteries and various electronics with similar specifications for remote area dwellers. However, solar panels are very inefficient when directly connected to load. Therefore, application of maximum power point tracking (MPPT) and pulse width modulation (PWM) to connect solar panels to laptop charger is presented in this work. This was achieved in this work through simulation and hardware implementation.

Hence, the need to meet this essential demand affordably and in an environmentally friendly manner. Therefore, an automatic hybrid water heating system (AHWHS) is proposed in this work, to heat up water for bathroom and kitchen use, using power supply from either the utility grid or an installed solar panel depending on certain factors such as availability and cost of solar resource, availability and cost of utility grid supply, water demand by consumers, etc. The AHWHS was designed and constructed by charging a battery from either the utility grid or solar panel, which then powers the direct current coil element to heat up the water needed for use in the home. The AHWHS was found to reduce household energy expenditure by 68.33% and 71.59% during low and high demand seasons respectively.

The absence of smart sensors, valves, and cylinders hinder the reporting of real-time state information about hydraulic motion controllers and pipeline networks. Legacy HD lacks active and structured communication protocols like Ethernet-IP. Unfortunately, these hydraulic flow systems are poorly designed during large-scale deployment at both residential and industrial areas. Cases of leakages and failures still abound. In some cases, there are no reference standards for IoT integration with fluid flow systems. In this paper, Volumetric IoT (V-IoT) sensors are introduced to monitor hydraulic flow systems leveraging route genetic algorithm. A state diagram for leakage amplitude monitoring is presented. Considering its node-to-node connectivity for steady-state monitoring, the enhanced V-IoT, with Genetic and Fibonacci algorithms offered leakage amplitude of 23.07%, 30.77%, and 46.16% respectively.

It eliminates the limitations in distributed communication involving Machine to Machine interactions among edge nodes in the substations. To achieve the aims; first, the edge layer for data stream parameter collection (from both homogenous and heterogeneous sources) is automated. Second, homogeneous linear-like Internet of Things (IoT) clusters are introduced for modular deployment at the distribution network. Third, interface protection monitoring for linear-chain topology in SGCN is deployed. To study the effect of the LCNO for system resilience, a simple routing protocol (SRP) is compared with Power-Efficient Gathering in Sensor Information System (PEGASIS) and Low Energy Adaptive Clustering Hierarchy (LEACH). Quality of service (QoS) results show that SRP is more efficient for monitoring the frequency and voltage parameters.
