Quantifying the Effects of Demand-Side Resources to Provide Flexible Ramping Products

Flexible ramping products have attracted widespread attention to address the importance of ramping capabilities in power systems and to formulate explicit prices of ramping capabilities. With the increasing penetration of renewable energy, demand-side resources become more important as the flexibility of traditional thermal generators is limited. In this paper, a real-time market model considering demand-side resources and a parametric programming method are proposed to analyze the potential of demand-side resources to provide flexible ramping products. The numerical results show the efficiency of demand-side resources to satisfy the system's ramping capability requirement and prove the effectiveness of the proposed model and method.
