Wind Power Capacity Value Metrics And Variability: A Study In New England, Frederick W. Letson Nov 2015

Wind Power Capacity Value Metrics And Variability: A Study In New England, Frederick W. Letson

Doctoral Dissertations

Capacity value is the contribution of a power plant to the ability of the power system to meet high demand. As wind power penetration in New England, and worldwide, increases so does the importance of identifying the capacity contribution made by wind power plants. It is critical to accurately characterize the capacity value of these wind power plants and the variability of the capacity value over the long term. This is important in order to avoid the cost of keeping extra power plants operational while still being able to cover the demand for power reliably. This capacity value calculation is …


Thermodynamic Analysis Of The Application Of Thermal Energy Storage To A Combined Heat And Power Plant, Benjamin Mcdaniel Jul 2015

Thermodynamic Analysis Of The Application Of Thermal Energy Storage To A Combined Heat And Power Plant, Benjamin Mcdaniel

Masters Theses

The main objective of this paper is to show the economic and environmental benefits that can be attained through the coupling of borehole thermal energy storage (BTES) and combined heat and power (CHP). The subject of this investigation is the University of Massachusetts CHP District Heating System. Energy prices are significantly higher during the winter months due to the limited supply of natural gas. This dearth not only increases operating costs but also emissions, due to the need to burn ultra low sulfur diesel (ULSD). The application of a TES system to a CHP plant allows the plant to deviate …
