A Case Study on Methods for Bibliometric Analysis of Research: Renewable Energy

A Study about Methods for Bibliometric Analysis of Research: Renewable Energy

Abstract: This paper presents methods and software implementation for analyzing a field of research through the use of bibliometrics, i.e., information about published journal articles. Online publication search engines are queried, and their search results are extracted and analyzed, to help inform a researcher of the state of his or her field. Our methodology consists of three components: extraction of terms relevant to the research field, analysis of the growth in prevalence of these terms over time, and identification of interrelationships among these terms using a technique known as Latent Semantic Analysis. These methods are applicable to the analysis of any research field, but this paper presents results from a case study on the field of renewable energy.

Case Study on Renewable Energy

Introduction: For researchers in a technical field, understanding the state of their area of interest is of the highest importance. Any research field is composed of many subfields and underlying technologies which are related in intricate ways. This composition, or “research landscape,” is not static. New technologies are constantly developed, while old ones become obsolete. Fields that are presently unrelated may one day become dependent on each other’s findings. An invention from decades prior may find a new application in an emerging field. Expertsin a field could already have a strong understanding of their research landscape. But it would be unreasonable to expectthem to have intimate knowledge of every aspect of theirfield. More critically, fledgling technologiesthat could one day play an importantrole are unfortunately the ones of which they aremostlikely unaware. Keep reading…

A Study on Geomagnetically Induced Currents and Their Effect on Power Systems

A Study about Geomagnetically Induced Currents and Their Effect on Power Systems

Abstract: High-impact, low-frequency (HILF) events pose a threat to power grids around the world. For example, solar storms that generate coronal mass ejections can induce a change in the Earth’s magnetic field. Geomagnetically induced current (GIC) then enters the power grid and causes unusual real and reactive power flows, voltage fluctuations, frequency shifts, undesired relay operations, high third-harmonic currents and telemetry and supervisory alarm failures. A storm on the order of 5,000 nT/min could occur in the not too distant future. Once this storm occurs, widespread damage to the power grid of unprecedented proportions is expected to result. Mitigation strategies are required to protect the integrity of the power system. Mechanisms involved in system restoration need to be prioritized, and the effectiveness of existing black-start procedures needs to be assessed.

Case Study on Effect on Power Systems

Introduction: High-impact low-frequency (HILF) events currently pose a threat to the power grids around the world. Two HILF events of popular discussion include high-altitude electromagnetic pulse detonation (HEMP) and geomagnetic disturbances (GMDs) due to space weather. This thesis concentrates on the effect of GMDs on the power grid. The susceptibility of power grids to GMD events is an ever increasing problem. A single event, lasting just a few minutes, has the potential to cripple portions of the power grid for weeks, even years.The ability to assess the impact of GMDs on a power system is limited. Tools are not widely available for power engineers to make this assessment. The goal of this research is to develop algorithms for better modeling and mitigating the impacts of geomagnetically induced current (GIC) on the power grid. Keep reading..

A Case Study on Effects of Deregulation and Vertical Unbundling on the Performance: Electricity Generation Sector

A  Study about Effects of Deregulation and Vertical Unbundling on the Performance: Electricity Generation Sector

Abstract:~ We study whether the 2002 deregulation and vertical unbundling of the Chinese electricity sector has boosted productivity in the generation segment of the industry. Controlling explicitly for sources of price-heterogeneity across firms and for firm-fixed effects, we find deregulation to be associated with a reduction in labor input and material use of 6 and 4 percent, respectively. This effect only appears two years after the reforms, is robust to alternative ways of identifying restructured firms, and to the nonrandom selection of restructured firms using a matching estimator. Input use of new state-owned firms that start operations two years into the reform period does not differ significantly anymore from input use of private sector entrants.

Case Study on Electricity Generation Sector

Introduction:~ We study whether the 2002 deregulation and vertical unbundling of the Chinese electricity sector has boosted productivity in the generation segment of the industry. Efficient operation of electricity plants is particularly important in China for several reasons. The manufacturing sector accounts for an unusually large share of the economy and it requires reliable and ever increasing amounts of electric power. Half of all provinces have suffered rolling brownouts in the last decade because of local capacity shortages and refusals of producers to generate electricity when generating costs surpassed regulated prices. Total electricity demand continues to grow and new capacity is constantly added. Keep reading..

A Case Study on Enhanced Oil Recovery

Study about Enhanced Oil Recovery

Executive Summary: Carbon dioxide enhanced oil recovery (EOR) is an oil extraction method that recovers additional stranded oil from aging oil fields while permanently sequestering CO2 in place of the oil. EOR is one type of carbon capture and storage (CCS), a climate mitigation strategy that attempts to reduce CO2 emissions to the atmosphere by permanently storing CO2 in geological formations. While oil produced via EOR still releases CO2 to the atmosphere when it is burned, this method reduces the oil’s carbon footprint as compared oil obtained through conventional methods and provides a significant opportunity to reduce the carbon emissions from conventional transportation fuels. With numerous depleted oil fields and industrial sources of CO2 in the Midwest, EOR is a potentially large source of low-carbon fossil fuel here. In addition to a lower carbon footprint, the application of EOR to existing oil fields provides energy security benefits to the Midwest and reduces the need to exploit new fossil fuel resources in previously untouched areas.

Case Study on Enhanced Oil Recovery

The reduced carbon footprint of EOR is not widely recognized in the Midwest as a promising opportunity to meet carbon-reduction goals in transportation sector. Biofuels, hydrogen, and electric vehicles all attract greater attention from policymakers and the general public, but EOR has unique characteristics that warrant consideration as a carbon-reduction tool. The carbon-reduction opportunities of EOR are especially pertinent with low carbon fuel policies that are designed to reduce greenhouse gas emissions from transportation fuels using lifecycle analysis. These policies, such as a low carbon fuel standard (LCFS), seek to reduce the sum of the greenhouse gas emissions associated with every step of a fuel’s production, refining, and distribution. An examination of how EOR produces additional oil using industrial CO2 not only illustrates how this process can reduce carbon emissions, but it is also useful to examine the risks and benefits of EOR.

A Case Study on Concentrating Solar Power Technologies

A Case Study about Concentrating Solar Power Technologies

Executive Summary: This case study reviews past and current experience in international collaboration in the field of concentrating solar technologies in order to identify lessons that may be relevant for more general climatefriendly technology collaboration. It presents concentrating solar technologies in their current status, recent achievements and development prospects. It analyses the present successes and failures of different forms of international collaboration in this field, and draws lessons for further elaboration of international technology collaboration in addressing climate change.

Case Study on Solar Power Technologies

Concentrating solar technologies concentrate solar light to raise the temperature of a transfer fluid and run turbines and electric generators; they might also be used to produce hydrogen or other energy carriers. In regions with high direct solar insolation they can provide on-grid power at a lower cost than other solar technologies, though higher than fossil-fuelled plants. This power can be made dispatchable through heat storage of fossil-fuel back-up at a moderate cost, due to the use of turbines and electric generators. Though proven by more than 15 years of satisfactory experience in California, these technologies are still in their infancy; research and development efforts, combined with early deployment, may bring them to competitiveness in the power markets within one decade or so.

A Study for Energy Subsidy Reform

A Study about Energy Subsidy Reform

Introduction: The selection of countries for the case studies reflects the availability of data and of previously documented evidence on country-specific reforms. The 22 country case studies were also chosen to provide cases from all regions and a mix of outcomes from reform. The studies cover 19 countries, including seven from sub-Saharan Africa, two in developing Asia, three in the Middle East and North Africa, four in Latin America and the Caribbean, and three in Central and Eastern Europe and the CIS.

Case Study on Energy Subsidy Reform

The case studies are organized by energy product, with 14 studies of the reform of petroleum product subsidies, seven studies of the reform of electricity subsidies, and a case study of subsidy reform for coal. The larger number of studies on fuel subsidies reflects the wider availability of data and past studies for these reforms. The structure of each case study is similar, with each one providing the context of the reform and a description of the reforms; discussion of the impact of the reform on energy prices or subsidies and its success or failure; mitigating measures that were implemented in an attempt to generate public support for the reform and offset adverse effects on the poor; and, finally, identification of lessons for designing reforms. keep reading…

Case Study on Regional Power Sector Integration

A Study about Regional Power Sector Integration

Developing countries are increasingly pursuing—and benefitting from—regional power system integration (RPSI) as an important strategy to help provide reliable, affordable electricity to their economies and citizens. Increased electricity cooperation and trade between countries can enhance energy security, bring economies-of-scale in investments, facilitate financing, enable greater renewable energy penetration, and allow synergistic sharing of complementary resources.At the same time, many RPSI efforts around the world are currently facing challenges that slow progress and mitigate the full benefits of greater integration.

Case Study on Power Sector Integration

These challenges include: difficulty aligning national and regional investment decisions; differences in regulatory environments between countries; insufficient regional institutions; dearth of financing; changes in political frameworks; and national sovereignty and energy independence concerns.This briefing note draws from the experiences of RPSI schemes around the world to present a set o findings to help address these challenges. keep reading…
