Resumen:

Spinning reserves of generating units are essential for the stability, continuity, and reliability of electrical power systems. However, the increasing integration of wind farms (WF) into power grids has led to a reduction in power reserves due to the displacement of conventional plants based on synchronous generators. Therefore, some grid codes require WF to provide this auxiliary service, which can be achieved by operating variable speed wind turbines (VSWT) in deloading mode. To this end, this paper presents an optimal power flow (OPF) model with WF complying with spinning reserves considering that VSWT use pitch angle control deloading. One where the WF distributes the responsibility of providing spinning reserves among VSWT according to their operating points. As a result, the specific blade pitch angle of each wind turbine contained in the WF is obtained. The present approach is applied to the IEEE 5-bus test system with an 80-MW wind farm comprising 40 turbines. The power system operation is compared with and without the WF, over a period of 12 hours with varying operating conditions, i.e., using variable patterns of system demand and wind speed. © 2023 IEEE.
