Analytical models for wind power investment

Cheng, Mang-kong., 鄭孟剛. January 2011 (has links)
Wind power generation has experienced an explosive growth worldwide. It is a promising renewable energy source to countries that are short of fossil fuels, e.g. China. While wind power is a distinctive direction to go for, it is still necessary to examine the rationale behind such investing mania, and this thesis analyzes the issue by collectively investment modeling. For investment analysis, it is necessary to first identify the relevant market background before inferring to any analytical model. Chapter 2 identifies a number of wind power investment scenarios in accordance to modern electricity market regime, primarily American and European structures. Among them, two main scenarios are investigated and modeled subsequently: fixed tariff wind power project invested by independent power producer and wind power project undertaken by utility. It has to be emphasized that different market scenarios would lead to different modeling methodologies for best representing the reality. Wind power is intermittent and uncertain. One way to describe the probabilistic energy production is by statistical characterization of wind power in a period of time. Chapter 3 presents a standalone analytical model of the wind power probability distribution and its higher order statistics. Large-scale deployment of wind power would influence power system in unprecedented ways. High penetration wind power poses a need of refinement to existing methodologies on production costing and reliability evaluation. The applications of the probabilistic wind power model to these topics are outlined in this chapter. In Chapter 4, investment of fixed tariff wind power project is analyzed. Operation of wind farm is very passive and as long as wind keeps blowing, such wind power investment has minimal risk in annual revenue. The low-risk profile facilitates debt financing. This leads to the attempt to manipulate the project capital structure to maximize the project levered value. Yet the default probability is raised and associated with a subjective value of default probability there is a value-at-risk debt level. I therefore propose an optimization formulation to maximize the wind power project valuation with debt as decision variable subject to the value-at-risk debt constraint. Apart from independent wind power producers, many policy and market factors driving wind power development are actually put on the utility side, e.g. Renewable Portfolio Standard (Renewable Energy Target) in U.S. (Europe) and Green Power Programs. It implies that utility has to have wind power (or other renewable) capacity ready by a certain date. In practice, utility may take action earlier if conditions are favorable or optimal. The conditions considered here are fossil fuel prices or in more general setting, electricity contract prices. Define the total fuel cost saving from conventional units as the benefit of wind power. If fuel prices are high enough, substituting load demand by wind energy is profitable, vice versa. The investment decision is analogous to premature exercising of an American option, in which the wind power project is modeled as real option. Chapter 5 offers detailed formulation of this idea. / published_or_final_version / Electrical and Electronic Engineering / Doctoral / Doctor of Philosophy

Small power, three to one phase matrix converter for wind generators

Ehlers, P, Richards, CG, Nicolae, DV 15 May 2013 (has links)
This paper investigates the concept of an isolated small wind power system based on a three-phase generator and a direct ac-to-ac conversion. The ac-to-ac conversion is performed by a matrix converter and thus removing the need of a large smoothing capacitor in the typical rectifier-inverter solution. The paper is briefly presenting the operation for a particular topology of a three-phase to single-phase matrix converter. The control of this conversion ensures system’s frequency and voltage stability. Simulation results and practical results are presented to validate the frequency and voltage regulation of the isolated power system.
