  7. Abstract:
  8. The penetration of renewable energies in generation section of power systems caused many issues and challenges for planners, operators and decision makers. One significant challenge is the uncertainty and variability of this type of generation, which must be properly covered; otherwise it would lead to wide load and supply curtailments. In this regard, some system operators introduced a new product, named Flexible Ramping Product (FRP) to their markets. FRP is the ramp capability of market participants which is reserved to cover the uncertainty and variability of net load (load minus intermittent supply) at next market time-interval of real-time market. With this in mind, the energy storage systems (ESSs), due to their high ramp capability, are always known as resources to response the variations of demand and supply. In this thesis, a novel FRP model and an appropriate framework for ESSs participation in FRP market is presented. The novelties of this thesis is divided to two main sections: a) A comprehensive model of FRP is proposed to penalize and award the participants according to their behavior in real-time market, the participants cause uncertainty are penalized proportionally and the particpants that their production capacity is reserved to cover the uncertainty are compensated. b) An appropriate framework for ESSs’ participation in procuring FRP by ISO and the optimal price-based unit commitment by ESS owners is developed. All the proposed formulations and models are mixed-interger linear programming and simulations are conducted on the modified IEEE-118 bus test system
