Security-constrained expansion planning of fast-response units for wind integration

The increasing socio-environmental concerns have persuaded decision makers to support large integrations of WG (Wind Generation) in power systems. Renewable generation is fuel-free and clean which would reduce the cost of electricity production and delivery. On the other hand, WG is volatile and intermittent. WG uncertainties could decrease the expected payoff of a GENCO (Generation Company) and possibly reduce the investors' interest in the WG capacity planning. Chapters 2 and 3 in this study have developed sophisticated mechanisms for proper WG expansions Chapter 4 discusses that proper long-term and mid-term operations planning which would included the simulation of power system uncertainties could provide a wider range of global options for managing the reliability and economics in power systems operations. From a power system's viewpoint, WG fluctuations could lead to additional system reserve requirements and the adoption of fast-response units for reliability purposes which would result in higher operation costs. Indeed, such conflicts between reliability and economics are inevitable in competitive environments. The optimal capacity expansion of renewable generation and fast-response capacity is the main theme of this dissertation Chapter 5 discusses that the large integration of WG would also affect other generation resources including fossil fuel based and hydro units. A proper long-term or mid-term operation planning study is required to investigate the coordination of various generation resources.;This dissertation offers algorithms for managing tradeoffs between profitability and reliability. The dissertation discusses assumptions, functions, and methodologies for the large integration of WG that would maximize profits of self-interested GENCOs and enhance the power system operation reliability at the presence of uncertainties.
