Techno-Economic Analysis Of Hydrogen Fuel Cell Systems Used As An Electricity Storage Technology In A Wind Farm With Large Amounts Of Intermittent Energy, Yash Sanghai
Masters Theses 1911 - February 2014
With the growing demand for electricity, renewable sources of energy have garnered a lot of support from all quarters. The problem with depending on these renewable sources is that the output from them is independent of the demand. Storage of electricity gives us an opportunity to effectively manage and balance the supply and demand of electricity. Fuel cells are a fast developing and market capturing technology that presents efficient means of storing electricity in the form of hydrogen. The aim of this research is to study the impact of integrating hydrogen fuel cell storage system with a wind farm to …
Background And Available Potential Energy In Numerical Simulations Of A Boussinesq Fluid, Shreyas S. Panse
Background And Available Potential Energy In Numerical Simulations Of A Boussinesq Fluid, Shreyas S. Panse
Masters Theses 1911 - February 2014
In flows with stable density stratification, a portion of the gravitational potential energy is available for conversion to kinetic energy. The remainder is not and is called “background potential energy”. The partition of potential energy is analogous to the classical division of energy due to motion into its kinetic and internal components. Computing background and available potential energies is important for understanding stratified flows. In many numerical simulations, though, the Boussinesq approximations to the Navier-Stokes equations are employed. These approximations are not consistent with conservation of energy. In this thesis we re-derive the governing equations for a buoyancy driven fluid …
Development Of A Decision Tool For Green Energy Investment In The Pioneer Valley, Benjamin R. Ewing
Development Of A Decision Tool For Green Energy Investment In The Pioneer Valley, Benjamin R. Ewing
Masters Theses 1911 - February 2014
We present the process followed to create a decision-aid tool for use in renewable energy and energy efficiency investment decisions. Our tool is targeted at home and small business owners in the Pioneer Valley. We begin with the development of two prototype tools. The first was created for the Hitchcock Center for the Environment, and is an Excel-based tool that allows users to select various combinations of technologies and instantly see the financial, environmental, and educational impacts of their choice. The second examines only two technologies, solar photovoltaics and combined heat and power, and uses a cost minimization approach. These …
Reliability Assessment Of A Power Grid With Customer Operated Chp Systems Using Monte Carlo Simulation, Lokesh Prakash Manohar
Reliability Assessment Of A Power Grid With Customer Operated Chp Systems Using Monte Carlo Simulation, Lokesh Prakash Manohar
Masters Theses 1911 - February 2014
This thesis presents a method for reliability assessment of a power grid with distributed generation providing support to the system. The distributed generation units considered for this assessment are Combined Heat and Power (CHP) units operated by individual customers at their site. CHP refers to the simultaneous generation of useful electric and thermal energy. CHP systems have received more attention recently due to their high overall efficiency combined with decrease in costs and increase in reliability. A composite system adequacy assessment, which includes the two main components of the power grid viz., Generation and Distribution, is done using Monte Carlo …
