Modeling and Control Framework to Ensure Intra-dispatch Regulation Reserves

Abstract

An automated control framework for cost-effective intra-dispatch real-power balancing is proposed in this chapter. The control objective is to balance the sustained variations in wind power, resulting from nonzero mean energy offsets around the wind power’s forecast or scheduled value, between two consecutive dispatch actions. The proposed control is an automated function that will track intra-10 min supply-and-demand imbalances caused primarily by sustained wind ramps. The balancing objective is achieved by ramping the slow generation resources from their scheduled dispatch, thereby minimizing the need for fast regulation reserves.
