J.; Nwohu, M. N.; Ambafi, J. G. Abstract: This paper emphasis on Load frequency control of a micro-grid using fractional order proportional integral derivative (FOPID) controller based. The microgrid consist of wind energy, solar energy, ultra-capacitor, and diesel generator. The main objective is to design a robust controller that can ensure good frequency control of the micro-grid by reducing the fluctuations of the system frequency during addition or withdrawal of load, perturbation, or change in weather due to renewable energy sources. The mathematical model of the micro-grid is developed and simulated using MATLAB/SIMULINK. The results of frequency deviation obtained by robust FOPID and PID controller are compared for model validation and represented in per unit as well as the deviation response. The former depicts a better load frequency control with reduced overshoot and low settling time.

G. Abstract: Demand for energy management solutions has grown due to global concerns about energy consumption and its environmental impact. The upward trajectory of CO2 levels in the atmosphere is unsustainable for the near future, potentially leading to a significant increase in average global temperatures and extreme weather conditions like drought, heatwaves and floods. These conditions could further jeopardise food security and affect 30-132 million people's livelihoods. Carbon footprint tracking can help identify areas of high emissions and implement strategies to reduce them. Cloud-based IoT device deployment with real-time data visualisation can improve energy efficiency and cut energy costs by monitoring consumption, remotely controlling energy use, predicting maintenance needs and optimising energy usage. This review analyses the various energy management strategies and the benefits of using an IoT-based carbon footprint tracking system for demand-side energy management, the potential to effectively support the achievement of UN SDG 12 &13 goals within the desired timeframe and the need for further innovation. Carbon footprint is a valid metric and feedback in demand-side energy management for urban settlements (70% of electricity usage), where cost as a metric has proven inefficient. This indicator can significantly influence the behavioural attitudes and changes in electricity usage patterns of all electrical customers.

Authors: Ambafi, J. G.; Adamu, S. S. Abstract: This paper investigates the effects of Static Synchronous Compensator (STATCOM) on electromechanical oscillations damping in a wide area network of power system. It focuses on the use of STATCOM and Phasor Measurement Units (PMU) to damp generators speed deviations and bus voltage profile improvement. The network performances were evaluated without remote centre called Power Oscillation Damper (PDC) serving as input to STATCOM in enhancing the system stability. The case study was mathematically modelled using system parameters in Power System Analysis Toolbox (PSAT) environment where most of the simulations were carried out. Finally, the overall performance of the network was evaluated by nonlinear simulations, and results obtained showed the effectiveness of the use of remote inputs in improving the dynamic stability of the system and provided better damping to the power swings.

Authors: Nwohu, M. N.; Ambafi, J. G.; Abubakar, B. Abstract: The rate at which the global automotive industry advances in technology with its attendant benefits in eco-friendliness has become a wake-up thought to Nigerian automotive industries. With the available resources and technical know-how in Nigeria for the production of internal combustion engine (ICE) automobile, there should be nascent interest and political will to produce Electric Vehicles (EVs) as well in Nigeria. However, the challenges of insufficient, unstable electricity supply, good road network, procurement of batteries and provision of charging facilities critical for the EVs will have to be tackled to realise the vision as elucidated in this study. It is hoped that the recommendations prescribed would be a good roadmap for a promising country like Nigeria to compete favourably with other developed countries in EV production.
