| dc.description.abstract | Global initiative to reduce the carbon footprint from the environment is transforming the modern power system. Growing integration of uncertain and intermittent renewable energy source like wind generation and increased number of electric vehicles in automotive industry will create difficulties in balancing supply and demand. This will change the power flow in the system, which will create the congestion in the existing transmission line reducing the overall system reliability. There is ongoing research and development in smart grid resources such as energy storage, var compensator, dynamic line ratings and communication devices to increase the capability of existing line to alleviate the congestion and maintain the continuity of supply to the bulk load points. Further, the existing transmission infrastructures are vulnerable to extreme weather events, such as windstorms that are occurring more frequently. There is a growing need for appropriate investment in modern transmission resources to ensure reliable and resilient transmission systems in the changing scenario. The value-based reliability assessment is necessary to justify the worth of any investment in the power system. The worth of investment comes from the reduced outage cost. Generally, generation facilities comprise the most capital investment for an electric utility. Therefore, the outage cost data available in published reports and past surveys associated with generation inadequacy. The customer power outage from insufficient generation mainly occurs during the peak demand period. However, the outages due to transmission resource failure can occur at other periods with specific probabilities. This thesis presents a methodology to estimate the cost of power interruptions originated from transmission component failures. The methodology proposes a sector periodic model for each customer sector to obtain the associated demand normalized outage costs. Furthermore, the thesis utilizes the outage cost obtained from the methodology to evaluate the reliability and resiliency worth of investments in the transmission grid facilities and technologies. The thesis presents a method to assess the reliability worth of investments in advancing transmission technology to enhance the grid reliability. The thesis also presents a method to assess the resiliency worth of investing into the infrastructure hardening to improve grid resilience against extreme wind events. | |
