| dc.description.abstract | Environmental concerns arising from the conventional generating sources have resulted in extensive growth of renewable energy sources (RES) such as wind and solar. The inherent variability and uncertainty of RES introduce major concerns in power system planning and operation to maintain an acceptable level of supply reliability and system efficiency. Energy storage systems (ESS) are considered as a potential option to mitigate the challenges associated with large scale RES integration. Bulk-scale ESS such as compressed air energy storage (CAES) are expected to take a prominent role in the future sustainable power system with high penetration of RES. This thesis investigates the reliability benefits of CAES in a wind integrated power system. The reliability contribution of a CAES depends on the operating strategy as well as the technical characteristics. The operating strategy of a CAES is dependent on the number of factors such as the existing market structure, objective of the owner and the intended application. Such factors need to be accurately accounted while developing a reliability model for CAES. This work develops a novel reliability assessment framework for a power system consisting of wind and CAES. The component reliability model of CAES is also developed and incorporated in the overall framework. The applications of CAES to seasonally and diurnally time shift energy are explored. The reliability benefit of CAES, as well as the capacity value increment of wind due to CAES, are quantified. The environmental benefits of CAES from its support to wind power and the financial benefits for a CAES from the existing electricity markets are evaluated. The impact of CAES operation on its potential benefits is analyzed. Furthermore, appropriate models and methodologies are developed in this work in order to quantify to the overall societal benefits of CAES considering the reliability impact, economic aspects, and environmental objectives. The feasible applications of CAES in wind integrated power systems are formulated and the potential benefits of CAES are assessed. The assessment of CAES benefits provide insights to utilities and policy makers in formulating effective policies and regulatory structures that can attract ESS participation, sustain the growth of RES and ensure acceptable supply reliability. In general, the models and analyses in the work can be valuable for stakeholders regarding cost effective and reliable transition of power system towards sustainable solutions. | |
