Application of economic MPC to frequency control in a single-area power system

Abstract

Abstract-This paper presents a novel model predictive control scheme for frequency control in a single-area power system. The proposed controller provides set-point corrections to the system power generators, based on the solution to an optimal control problem. The optimal control problem directly incorporates the cost of operation into its objective function. A trade-off parameter is used to balance set-point tracking and cost minimization. Simulations based on a Faroe Islands case study show that the proposed approach reduces cost of operation by almost an order of magnitude, compared to both set-point based model predictive control as well as conventional frequency-based PI-control.

Economic and Distributed Model Predictive Control: Recent Developments in Optimization-Based Control

“…Concerning applications, economic MPC schemes have successfully been applied in many different fields, and it is well beyond the scope of this article to mention all of these. Examples include, among others, the process industry [106], [127], building climate control [128], the control of wind turbines [129], supply chain management [130], refrigeration systems [131], power systems [132], and the development of sustainable climate policies [133].…”

Predictive Active Power Control of Two Interconnected Microgrids

“…The authors have proposed an operation cost reduction approach considering an order of magnitude similar based on the difference ratio of two set points MPC and PI controller. Sokoler et al [30] have proposed an application of economic MPC for LFC considering a single area power system. The optimal operation control problem directly includes all the operation costs into its objectives function.…”
