Accurate and detailed energy demand estimates are crucial to achieving adequate energy infrastructure planning. These estimates are often non-existent or deficient in many developing countries, and consequently, electricity supply is unreliable. A novel approach for estimating electricity demand is presented. Our approach uses a global geographical population database with 1km2 spatial resolution as the foundational input. The use of spatial population data is based on the premise that electricity consumption is dependent on where people are located. These population counts are converted to electrical customers to create spatial power demand data which can be mapped. The resulting power demand maps could be valuable for energy infrastructure planning. In this study, Uganda is used as a pilot case-study. Analysis suggests that an additional 1.5 GW of power generation capacity needs to be availed to meet the lowest power demand scenario. The methodology developed can be extended to other regions of interest.

Improved electricity product development is becoming more significant to the business performance of electricity transmission companies. Despite the fact that the term improved/new product development is not new, very few studies have investigated the effect of improved electricity product development on the business performance of a public electricity transmission company, most especially in a developing country such as Nigeria. This paper present means by which improved electricity product development can be used to assist electricity transmission company's business performance in order to improve customers' electricity product adoption and other stakeholder's satisfaction in the industry. It is based on a case study of the Transmission Company of Nigeria (TCN), it provide guidelines to stakeholders in the industry in utilizing improved electricity product development to better support electricity transmission companies: it allows transmission companies to launch improved electricity products to end-users; it helps transmission companies to determine the weaknesses of the electricity product delivered to end-users; it allows improved quality of electricity product that customers are willing to pay a premium for, while eliminating epileptic electric-power supply end-users do not want.

The demand of energy is drastically increasing now days mainly in developing countries like Ethiopia. In connection, wind energy is one of the promising renewable energies sources with the most commonly used Doubly Fed Induction Generator (DFIG). The DFIG's stator is directly connected to the grid, whereas the rotor is tied via dual back-to-back Pulse Width Modulation (PWM) converters. Its active and reactive power can be controlled independently using converters as per the demand of system operators or grid code requirements. The PWM strategy has a capacity of giving higher converter output voltage by high switching frequency modulation process. Thus, this paper models the DFIG and uses PWM to control the power flow at rotor and grid sides independently. MATLAB-Simulink software is used for modeling and simulation. Finally, conclusions are drawn.

Recent architectures for the advanced metering infrastructure (AMI) have incorporated several back-end systems that handle billing and other smart grid control operations. The non-availability of metering data when needed or the untimely delivery of data needed for control operations will undermine the activities of these back-end systems. Unfortunately, there are concerns that cyber attacks such as distributed denial of service (DDoS) will manifest in magnitude and complexity in a smart grid AMI network. Such attacks will range from a delay in the availability of end user's metering data to complete denial in the case of a grounded network. This paper proposes a cloud-based (IaaS) firewall for the mitigation of DDoS attacks in a smart grid AMI network. The proposed firewall has the ability of not only mitigating the effects of DDoS attack but can prevent the attack before they are launched. Our proposed firewall system leverages on cloud computing technology which has an added advantage of reducing the burden of data computations and storage for smart grid AMI back-end systems. The openflow firewall proposed in this study is a better security solution with regards to the traditional on-premises DoS solutions which cannot cope with the wide range of new attacks targeting the smart grid AMI network infrastructure. Simulation results generated from the study show that our model can guarantee the availability of metering/control data and could be used to improve the QoS of the smart grid AMI network under a DDoS attack scenario.

Upcoming construction proposals for utility-scale photovoltaic plants and discussion of compensation in Nigeria raise the question of appropriate grid code requirements to support system voltage control objectives. The large geographical extent, long lines, and small number of generators in the Nigerian High Voltage System make voltage control a critical issue. This paper evaluates the effect of different power control strategies for a 100 MW solar plant, using dynamic simulation of a detailed grid model. The choice of location in North of Nigeria informs ongoing discussions, and is the first published study of this type. The effect of the strategies are compared, and recommendations are made for transmission system operators and developers to consider as they define interconnection agreements.

Access to energy is one of the primary cause contributing to the disparity between developed and developing nations. Nearly 600 million people in Africa lack access to electricity which majority of them residing in the sub-Saharan African (SSA) countries. Electricity consumption in SSA countries excluding South Africa is 153kwh/year. The current installed capacity is at 147 GW which is equivalent to China's install capacity for one or two years. The road to electrification in SSA countries is either through grid extension, high penetration of off-grid technologies such as standalone systems and microgrids. Given the abundant natural and vast geographical advantage, the potential for renewable energy sources is vast in SSA countries. This paper aims to present detailed review on the ongoing renewable energy supported technology for rural electrification of sub-Saharan Africa region. It will discuss issue of energy poverty and why that is directly related to the lagging economy of these countries. It will detail some of the off-grid and microgrid developments. Challenges facing this development will be discussed. Finally, it will conclude by reflecting on the impact of the future off-grid renewable technologies, the status and challenges of rural electrification.

Adequate generation capacity to meet the increasing demand of electricity has remained the main focus of both developed and developing economies. In order to maintain the safety of generation and distribution systems, constant load shedding is employed to maintain equilibrium between overall generation and total demand per unit period. This paper proposes a distribution management algorithm to micro-load manage the load shedding process by considering households and all electricity based devices as unique loads that can be individually managed. Consequently, the proposed algorithm prevents total blackout in communities affected by the load shedding. Experiments were conducted on a simulation environment made up of over a 25 households each equipped with a smart meter, and loads of varied quantity and types. The results obtained from the experiment show that our proposed micro-load management algorithm is effective for micro-load managing demands in near real time.

The Nigerian Power System Network is presently characterized by poor reliability with respect to customer's uncertainty with respect to how long the electric power supplied can last before they are put on load-shedding or otherwise. Data was collated from the daily operational log books of five feeders emanating from the Transmission Company of Nigeria, Benin City, Nigeria. The reliability indices have been calculated and the results interpreted using a spreadsheet. A mathematical model has also been developed for the network using the curve fitting tool in the MATLAB (2013) environment and a corresponding Simulink model was eventually developed from the mathematical model. The results show that the priority feeder has the highest reliability of 97.8% while the feeders characterized with obsolete equipment has the least reliability of 78.4% The results further shows a deviation from the world and ASAI Reliability and Availability standard an indication that the feeders needs to be optimized for a better productivity.
