Abstract

 

This article presents a novel control scheme for achieving optimal power balancing and congestion control in electrical energy transmission networks via nodal prices. We develop an explicit controller that guarantees economically optimal steady-state operation while respecting all line flow constraints in steady-state. Due to these constraints, the resulting optimal control law has a piecewise affine structure. To optimize the dynamic response of the system and to satisfy line overload constraints during the transient period, the explicit optimal controller is complemented with a hybrid MPC controller. An example illustrates the effectiveness of the proposed hybrid control scheme.
