Abstract
Electricity generation via conventional generating systems is faced with challenges such as emission of greenhouse gases, uncertainty associated with fossil fuel prices and incidences of failure or outages of generation. This dissertation proposes the incorporation of largescale Renewable Energy Sources (RES) into power systems in order to reduce the challenges associated with conventional generating systems. The first part of this dissertation investigates the contribution of RES and economic incentives to the composite generation and transmission expansion planning procedure. A Mixed Integer Quadratic Programming (MIQP) model based on composite generation and transmission expansion planning is proposed for solving a multi-objective mathematical optimization problem which includes minimization of the investment costs, operational costs, emissions as well as the maximization of economic incentives. Obtained results, when compared with previous works indicate that encouraging economic incentives improves the effective utilization of offshore wind farms and consequently reduces the emissions from conventional generating units....
