A Low-Cost Secure Iot Mechanism For Monitoring And Controlling Polygeneration Microgrids, Josué Martínez-Martínez, Diego Aponte-Roa, Idalides Vergara-Laurens, Wayne Weaver
Michigan Tech Publications
The use of Internet-connected devices at homes has increased to monitor energy consumption. Furthermore, renewable energy sources have also increased, reducing electricity bills. However, the high cost of the equipment limits the use of these technologies. This paper presents a low-cost secured-distributed Internet of Things (IoT) system to monitor and control devices connected in a polygeneration microgrid, as a combined power system for local loads with renewable sources. The proposed mechanism includes a Wireless Sensor Actuator Networked Control System that links network nodes using the IEEE 802.15.4 standard. The Internet communication enables the monitor and control of devices using a …

The Integrated Rural Energy Planning (IREP) framework offers a unified road map for locating, planning and operating decentralized renewable hybrid off-grid energy systems for localized (rural) applications in low-income countries. This paper presents the culmination of the IREP framework and aims to illustrate the final step of the IREP framework for two communities in Nigeria. It is focused on two aspects. Firstly, the techno-economic modeling (investment and operation optimization) of a hybrid mini-grid system using HOMER Pro, a techno-economic evaluation tool; and evaluating the benefits of demand side management (DSM) based on energy efficiency on the overall system economics using …

Potential Energy Generation From Agricultural Residue In Indonesia, Adrian Rizqi Irhamna
Potential Energy Generation From Agricultural Residue In Indonesia, Adrian Rizqi Irhamna
English Language Institute
Indonesia has great potential of biomass sources from their agricultural residue, which can potentially be used for alternative energy generation. This preliminary research explores the most suitable technology for energy generation from agricultural residue and its challenge for application in Indonesia. The study showed that biomass utilization via the direct combustion process is recommended for energy generation. It is also reported that the pretreatment process of drying and washing, are required to increase the fuel quality and plant efficiency.
What Are The Advantages Of Replacing Fossil Fuels With Biofuels?, Amr Shaalan
What Are The Advantages Of Replacing Fossil Fuels With Biofuels?, Amr Shaalan
English Language Institute
Fossil fuels’ negative impact on the environment is leading many people to worry In addition to that, fossil fuels are running out as every day goes by. Thus, finding a renewable and environmentally friendly source of energy has now become a necessity. Biofuels offer clean energy that comes with numerous economic and environmental benefits. Furthermore, biofuels can absorb more carbon from the air than they would produce when burnt. Giving a chance to clear the air from fossil fuel’s carbon.
Applying Renewable Energies Against Climate Change: Solar Photovoltaic (Pv) Energy, Juan Jose Estribi
Applying Renewable Energies Against Climate Change: Solar Photovoltaic (Pv) Energy, Juan Jose Estribi
English Language Institute
In recent years, more efforts towards fighting climate change have been done. As a direct response, research and technology have offered several insights regarding the specific causes, effects, and even possible solutions for resolving this global issue. Among these solutions, renewable energies and their potential contributions as clean energy sources can be assessed as feasible options for the energy transformation through the decarbonization process of the energy industry. This poster is mainly focused on solar photovoltaic (PV) energy and its great potential as a renewable energy by making a brief assessment of some important aspects such as resource availability, its …
An Assessment Of Renewable Energy Technology Implementation In Storrs, Connecticut: Emissions Reduction And Feasibility Of A Microgrid System At Uconn, Sophie Macdonald
An Assessment Of Renewable Energy Technology Implementation In Storrs, Connecticut: Emissions Reduction And Feasibility Of A Microgrid System At Uconn, Sophie Macdonald
Honors Scholar Theses
The purpose of this project is to design a clean energy-sourced microgrid for UConn’s main campus that would reduce the university’s energy emissions while remaining within the geographic boundaries of viable UConn-owned land. Economic cost was not considered in this analysis; instead, emissions and space constraints were the optimized measures of value and feasibility. Sources of energy that were considered include photovoltaics (PV), wind turbines, hydrokinetic systems, and fuel cells. Energy storage capacity was included in the analysis as well. The overall system was optimized first by ignoring space constraints and for a minimum of 10% reduction from the current …
Nanomechanical Characterization Of Fuel Cell Ionomers, Jackson Goddard
Nanomechanical Characterization Of Fuel Cell Ionomers, Jackson Goddard
UCARE Research Products
Energy sustainability can be achieved by improving and adopting clean energy technologies, and a better nanoscale understanding of ionomer-catalyst layers could lead to increased efficiency of proton exchange membrane fuel cells. Samples of Nafion ( Perfluorosulfonic acid ionomer) and PFIA (Perfluoroimide acid ionomer) of varying film thickness were prepared and then studied using contact resonance force microscopy. It was determined that storage and loss modulus increase as relative humidity increases and ionomer film thickness goes below 100 nm. Furthermore, in this specific study, the similar storage and loss modulus of Nafion and PFIA could be attributed to similar backbone structure …
Net Energy Index: A New Way To Measure Energy Efficient Buildings, Dylan Suplee
Net Energy Index: A New Way To Measure Energy Efficient Buildings, Dylan Suplee
Senior Honors Theses
Energy efficiency indexes are useful for providing tangible measurements of energy efficiency in buildings. Buildings use approximately 70% of all electricity in the USA. Using that energy efficiently has two primary benefits: limiting greenhouse gas emissions and reducing grid strain. Utilizing local renewable energy sources contributes to the same benefits. Currently, there is no index that considers renewable energy sources when measuring energy efficiency. Therefore, this paper proposes the Net Energy Index, which compares the net power usage of a building to the floor area of the building in order to determine energy efficiency. If renewable energy supplies power to …
Forecasting The Short-Term Value Of Wind Power For Risk-Aware Bidding Strategies In Single-Imbalance Price Electricity Markets, Gianni Goretti
Forecasting The Short-Term Value Of Wind Power For Risk-Aware Bidding Strategies In Single-Imbalance Price Electricity Markets, Gianni Goretti
Doctoral
The participation of wind energy in electricity markets and strategic bidding in the day-ahead market has been investigated with growing interest in recent years. However, markets adopting a single-price imbalance settlement where participants can increase their profits if they help to put the system back into balance have received very limited attention in the academic literature. In this thesis, new probabilistic models forecasting the short-term value of wind power are developed and their use in bidding in these types of markets is investigated. The proposed strategies are designed for participants who want to bid strategically in the day-ahead market to …
