Study of Transmission System with Wind Power Control and Optimal Reactive Power Flow

This paper presents a methodology of controlling the power injected into system by wind generators and the use of Optimal Reactive Power Flow (ORPF). The methodology used two stages: in the first one scheme for Doubly-Fed Induction Generator (DFIG) is realized to control the active and reactive powers, in the second stage, the ORPF based in the Modified Barrier Lagrangian Function approach (MBLF) is used to optimize reactive power dispatch aiming to minimize active power losses system. Case studies on the modified IEEE 14 bus "modified" clearly shows the benefits of using the associated generator control whit ORPF.

Artykuł przedstawia metodologię sterowania dołączaniem energii z elektrowni wiatorwych do systemu energetycznego oraz użytkowania algorytmu RRPF – Optimal Reactive Energy Flow. W pierwszym etapie analizowano sterowanie generatorem typu DFIG w celu kontroli mocy biernej i czynnej, w drugim etapie wykorzystano metodę MBLF (Modified Barrier Lagrangian Function) do optymalizowania mocy biernekj w systemie.
