Reactive Power Compensation and Voltage Support in Wind Farms

The demand of electrical energy in general and the wind energy specifically is increasing worldwide. The challenges to this energy especially issues related with reactive power compensation and voltage support are increasing. Adama-I wind warm is one of these wind energy systems in Ethiopia. To compensate reactive power, the wind farm is using static capacitor banks and magnetically Coupled Reactors (MCR) type Static Var Compensators (SVC). However, the capacitor banks are not fast enough to alleviate the problem. To mitigate the problem of the existing wind farm, a new emerging technology photo voltaic-static synchronous compensator (PV-STATCOM) device is conducted at the main substation or point of common coupling (PCC) of the wind farm. The solar inverter is used to act as STATCOM, at the main substation or at Point of Common Coupling (PCC) for active power regulation and voltage/reactive power regulations during night-time and daytime. This study will contribute special ideas for those who interested in study of applications of the new emerging solar source fed FACTs (TATCOM) devices in wind farm networks and any electric power networks.
