Ga Based Optimal Control For Maximizing Pv Penetration At Transmission, Chittesh Veni Chandran Jul 2016

Ga Based Optimal Control For Maximizing Pv Penetration At Transmission, Chittesh Veni Chandran

Student Journal of Energy Research

Utilization of distributed energy resources (DER’s) like photo-voltaic generators, is one of the possible solution for present scenario of energy crisis. Most of the study suggest the implementation of PV power stations at distribution level. In this paper detailed theoretical analyses of the impact of large scale PV on transmission level is analysed. The preliminary section of this paper provides literature review with specifications of IEEE-14 bus network. Two methodology ie, constant load method and maximum loading method is implemented here. A test study is done in IEEE 14 bus to find out the optimal location of solar photo-voltaic generator …


Risk Assessment For Two Multi Terminal Vsc-Hvdc Control Schemes, Roberto Sandano Jul 2016

Risk Assessment For Two Multi Terminal Vsc-Hvdc Control Schemes, Roberto Sandano

Student Journal of Energy Research

High Voltage Direct Current (HVDC) connections have been in operation since the 1950s. The vast majority of which are point to point connections and use Line Commutated Converter (LCC) technology. Since the late nineties Voltage Source Converter (VSC) technology has become a feasible choice on HVDC transmission systems [1]. Research is now focused in the development of Multi-terminal (MT)-HVDC system which will facilitate the collection of energy from distant dispersed renewable energy resources and transport this energy to load centres.


Power Quality Improvement In Fuel Cell Based Hybrid Power System Using Statcom, Sandipan Patra Jul 2016

Power Quality Improvement In Fuel Cell Based Hybrid Power System Using Statcom, Sandipan Patra

Student Journal of Energy Research

This paper presents the power quality improvement in a microgrid, supplying a nonlinear and unbalanced load using fuzzy logic controller based static synchronous compensator (STATCOM). The microgrid contains a hybrid combination photovoltaic (PV), fuel cell (FC) along with the battery energy storage system (BESS) where a decentralized power sharing algorithm is used to control its power management. Here, STATCOM is used as a compensator for the hybrid system to reduce the harmonics in the voltage and current profile at the point of common coupling (PCC). The current reference is generated taking into account, the active and reactive power to be …

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown Jan 2016

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric …


The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler Jan 2016

The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler

Journal of Environmental and Resource Economics at Colby

This paper seeks to address the effect of “Spare the Air” pollution control alerts in the San Francisco Bay Area in California on the use of Bay Area BikeShare as a form of transportation. By observing the daily alerts on the duration of rides using BikeShare, this paper observes if STA ozone alerts are effective in changing human behavior. The results show that only as a subscriber to the BikeShare program and on an alert day does duration decrease whereas customers regardless of if it is an alert day will ride more often and at longer distances. The results contradict …


Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou Jan 2016

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.


Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda Jan 2016

Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda

Journal of Environmental and Resource Economics at Colby

This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.


Media Effects On Solar Panel Installations Across 20 States, Casey Romeo Jan 2016

Media Effects On Solar Panel Installations Across 20 States, Casey Romeo

Journal of Environmental and Resource Economics at Colby

This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic …


Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff Jan 2016

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.


The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz Jan 2016

The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz

Journal of Environmental and Resource Economics at Colby

This paper examines the effectiveness of the Colby College electricity reduction competition in altering students’ behavior to conserve electricity. The Colby College electricity reduction competition is an information-based policy that Colby implemented to promote the conservation of electricity, which are a major contributor to greenhouse gas (GHG) emissions in the United States. The study analyzes if different residence halls reduce electricity consumption by different amounts during the competition period. Results indicate that only 4 of 22 residence halls reduced electricity usage during competition periods in a statistically significant manner. The study concludes that the electricity competition at Colby College is …
