Reactive Power Flow Optimization in Power Systems with Hierarchical Voltage Control

چکیده
The Hierarchical Voltage Control (HVC) has been adopted in some countries as a significant improvement of the traditional voltage control solutions. This paper deals with the Optimal Reactive Power Flow (ORPF) from a Multi-objective perspective. In particular, it studies the interactions between three objective functions (OFs): one is the “traditional” real losses minimization, while the other two are designed to deal more directly with the electric network security. The three OFs have been integrated in a Multi-objective problem, adopting a new formulation of the Power Flow which includes a HVC model; a deep analysis on HVC complementarity constraints is presented. The new ORPF has been tested on a realistic model of the Italian Transmission System by using the high level modeling tool GAMS.
