Domestic Demand Response to Increase the Value of Wind Power

This thesis describes a new method to evaluate the value of wind power combined with domestic demand response. The thesis gives a brief overview of current domestic demand management programmes, and highlights the demand response and its current application. Such technology has conventionally been used for different purposes, such as frequency regulation, and to minimize the spot electricity prices in the market. The aim is to show whether such technology may become useful to make the renewables, and in particular wind power more interesting for investors. An assessment framework based on generation scheduling is developed to quantify the value of wind power. A further important aspect of value of wind power is the impact of intermittency on overall reliability of the system. This necessitates increasing the spinning reserve level which will increase the production cost. The changes in the spinning reserve level has been investigated in this thesis and it has been shown that how different forecasting errors may change the overall value of a windfarm over its lifetime. One of the most important aspects of a system containing demand response, is the availability of demand response. A load modelling package is developed to show the potential for demand response in a real system from domestic sector. With every increasing the concerns with regard to future of generation mix in Britain, this work has proposed over 72 scenarios for the future of generation mix in Britain and the impact of demand response to increase the value of wind power in 2020 has been investigated. The assessment framework is enhanced by showing that how the value of wind power combined with domestic demand response may change by changes in emission price, and cost of demand response. This will show the degree of feasibility of such system in which demand response is treated like a commodity.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Smart frequency control for the future GB power system

Replacing fossil fuel burning synchronous generation with asynchronous renewable generation to deliver environmental goals will significantly reduce system inertia. Reduced inertia allows a faster and larger frequency deviation after a disturbance and the reduction in inertia in GB will be significant enough in the next decade that the existing frequency control will be too slow to contain the frequency deviation after a large disturbance. Therefore, delivering fast, coordinated frequency control from new service providers, e.g. energy storage, (termed 'smart frequency control') will be vital to overcoming the challenge posed by reduced/variable inertia in GB. This paper describes some of the challenges that must be overcome when delivering this form of control, in terms of controller design and the definition of a new ancillary service, alongside simulation results for a 36 zone equivalent model of the GB frequency response that illustrate these challenges and the threats posed by reduced inertia. © 2016 IEEE
