| Summary: | Stochastic nature of the wind speed is the main reason that leads to variability of output power of wind farm. Thus high penetration of the wind farm will cause power fluctuation and voltage variation in grid system. Current control method was designed to control power flow in the grid system hence the occurrence of fluctuant power can be eliminated in the network. A new technique using mathematical modeling was developed in designing the control system. The block diagram of this control system was built based on the dynamic analysis of the circuit by assuming the steady state condition. Some parameters for instance proportional and integral gain were determined based on the assumption of the values of line inductance, resistance and time constant . MATLAB/simulink tool was used to scrutinize the performance of the designed model. The performance of the designed control system is investigated by comparing the results between with and without control system and the results were also investigated in fault condition. The results show that the current control method has high potential in control power leveling in the grid system. |
