Abstract
In this work a multiobjective model predictive control for reactive power management in transmission connected distribution grids with high share of wind power is presented. The proposed control utilizes reactive power capabilities of wind farms and tapchanger positions in order to improve distribution grid operation. Control signals namely tapchanger positions and reactive power setpoints are smoothed over the forecast horizon. Further possible optimization objectives are power loss reduction, voltage profile smoothing and complying with reactive power exchange limits with the transmission grid. A mixedinteger nonlinear optimal power flow problem (MINLPOPF) is formulated incorporating grid operation limits. The performance is evaluated on a real German 110kV distribution grid with 1.6 GW wind power for one year. With the proposed control, reactive power exchange within allowable limits is increased from 58.3% to 94.5%, compared to a reference operation where on ly tapchanger positions are utilized for loss reduction with a single timestep optimization.
