PO496: Model for optimal coordinated control of reactive power support of wind farms connected to the transmission grid
Miroslav Zerajic, PhD student, University of Belgrade - School of electrical engineering
Abstract
The integration of variable renewable energy sources (RES), primarily wind power plants (WPPs) and photovoltaic power plants (PVPPs), into power systems has significantly increased their role in providing ancillary services. Among these, frequency regulation and voltage regulation are the most prominent. When variable RES are utilized for voltage regulation, the main challenge lies in balancing the perspectives of market participants and system operators. Service providers seek to maximize the range of reactive power that RES can absorb from or inject into the transmission grid, while system operators aim to minimize reactive energy exchange in order to reduce costs associated with voltage control services. To address these requirements, this paper proposes a model for optimal coordinated control of reactive power support of WPPs in the power system minimizing absorbed reactive power from the transmission grid or injected into the transmission grid, on an hourly basis, while ensuring that voltages at transmission grid busbars remain within the allowable operating limits. These setpoints may be calculated day-ahead, on an hourly basis, or for shorter intervals, and then dispatched as a sequence of setpoints from the transmission grid control center during the real-time operation. Such model ensures the coordinated deployment of reactive power from WWPs in accordance with the actual operational requirements of the transmission grid. In doing so, the model reduces the need for additional equipment dedicated to voltage control.
