High penetration levels of variable resources such as wind and solar power introduce significant uncertainty and variability into the power system, creating high and unpredictable ramps in net load. Such ramps present a great challenge for system operators who must maintain reliable operation and efficient markets with simultaneous maximum utilization of renewable energy. Incentivizing investment and market participation in providing flexibility by diverse resources on the supply and demand side requires new dispatch mechanisms and operating procedures.
In this talk a novel metric (Lack of Ramp Probability) for evaluating system-wide flexibility is proposed. Further a robust dispatch model is proposed, which provides guaranteed performance for this flexibility metric. This robust optimization-based economic dispatch model is compared with existing and industry proposed approaches through numerical case studies.
