Forecasting Nigeria's Electricity Demand And Energy Efficiency Potential Under Climate Uncertainty, Olawale Olabisi

Doctoral Dissertations

The increasing population and socio-economic growth of Nigeria, coupled with the current, unmet electricity demand, requires the need for power supply facilities expansion. Of all Nigeria’s electricity consumption by sector, the residential sector is the largest and growing at a very fast rate. To meet this growing demand, an accurate estimation of the demand into the future that will guide policy makers to adequately plan for the expansion of electricity supply and distribution, and energy efficiency standards and labeling must be made. To achieve this, a residential electricity demand forecast model that can correctly predict future demand and guide the …

Analysis Of Grain Product Drying Methods, Azizbek Nodirbekovich Yusupbekov, Dilmurod Egamberganov

Chemical Technology, Control and Management

Various drying methods and grain characteristics have been studied. The advantages and disadvantages of various grain drying methods were obtained. The use of the following methods of drying grain products is very useful for speeding up the drying process, reducing waste, achieving more flexible process management and delivering all the nutrients of dried grain and grain products to the subsequent production process. The technological approaches that increase the efficiency of high-quality production after drying grain products, the requirements for modern grain dryers have analyzed. The ways of overcoming the problem of high energy consumption in the process of drying grain …

Internet Of Things In Sustainable Energy Systems, Abdul Salam

Faculty Publications

Our planet has abundant renewable and conventional energy resources but technological capability and capacity gaps coupled with water-energy needs limit the benefits of these resources to citizens. Through IoT technology solutions and state-of-the-art IoT sensing and communications approaches, the sustainable energy-related research and innovation can bring a revolution in this area. Moreover, by the leveraging current infrastructure, including renewable energy technologies, microgrids, and power-to-gas (P2G) hydrogen systems, the Internet of Things in sustainable energy systems can address challenges in energy security to the community, with a minimal trade-off to environment and culture. In this chapter, the IoT in sustainable energy …

Energy Supply Chain Of Co-Firing System To Generate Electricity, Abinash Panda

Major Papers

The problem of air pollution on the streets of the national capital of India, New Delhi is a major concern. Majority of the pollutants are generally originated from either the vehicles on the roads or the burning of crops from the neighbouring states of the National Capital Region (NCR). To improve the condition of the air quality by the vehicles, implementation of the Electric Vehicles (EVs) in an energy supply chain is a suitable plan. The objective of this paper is to plan a supply chain of generation of electricity by the process of co-firing that prompts benefits both in …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Engineering Microbial Fuels Cells: Recent Patents And New Directions, Justin C. Biffinger, Bradley R. Ringeisen

U.S. Navy Research

Fundamental research into how microbes generate electricity within microbial fuel cells (MFCs) has far outweighed the practical application and large scale development of microbial energy harvesting devices. MFCs are considered alternatives to standard commercial polymer electrolyte membrane (PEM) fuel cell technology because the fuel supply does not need to be purified, ambient operating temperatures are maintained with biologically compatible materials, and the biological catalyst is self-regenerating. The generation of electricity during wastewater treatment using MFCs may profoundly affect the approach to anaerobic treatment technologies used in wastewater treatment as a result of developing this energy harvesting technology. However, the materials …

Exercising Real Unit Operational Options Under Price Uncertainty, Chung-Li Tseng

Engineering Management and Systems Engineering Faculty Research & Creative Works

In this paper, we use the real options framework to value the operation flexibility of a power plant. The power plant operation is formulated as a multi-stage stochastic problem. We assume that there are hourly spot markets for both electricity and the fuel used by the generator, and that their prices follow some Ito processes. At each hour, the power plant operator must decide whether or not to run the unit so as to maximize expected profit. However, the unit operation is subject to decision lead times and minimum uptime and downtime constraints, so the commitment decision must take into …
