Control óptimo de potencia reactiva en un parque eólico mar adentro con enlace HVDC

Abstract

This paper presents the optimal management of the reactive power in an offshore wind farm integrated into the main grid trough high voltage direct current (HVDC). The target is to reduce the power losses of the system. The components, equipment of an offshore wind farm and the integration ways to the main grid are outlined. The optimization problem is defined, clearly pointing out its objective function and constraints. Then, the optimization technique is selected. To check the performance of the optimization algorithm, a test system is implemented in DIgSILENT PowerFactory and the optimization technique through DIgSILENT programming language (DPL). The study cases are based on the different generating powers and different distances of the direct current transmission line. The power losses are compared under normal and optimal operating conditions.
