Robust Optimization for Power Market Considering Multi-Resolution Ramp Requirements

The electricity market rarely considers finer time resolution ramping requirements, which poses a risk to the safe operation of the power grid. Based on the smoothing effect that the average fluctuation of wind power output decreases with increasing time, this paper formulates a finer time resolution wind power output range. Considering the requirements for the ramping capability in this scenario, a detailed robust optimization modeling approach is proposed. The method introduced in this paper was validated through numerical examples.
