Modeling Preventive and Corrective Actions Using Linear Formulation

This chapter presents the various reliability management actions and a possible formulation to integrate these actions into a security constrained optimal power flow (SCOPF) environment. It discusses the linear implementation of different control actions in an SCOPF environment. The formulation of the preventive implementation of an action is discussed, after which the changes for the corrective implementation are highlighted. The different actions are represented using a linearized formulation. Linearization allows to keep the computational costs low while retainting a sufficiently accurate approximation of the behavior of the system. Many other formulations can be found in the literature. The main objective is to show how each of the different control actions can be implemented in a consistent manner and to illustrate the impact of such control actions. Each of the control actions add a number of constraints to the optimization program, and alter the objective function.
