Simulation Study on Maximum Injection Power of Wind Farm

The grid connected operation of wind farm will lower the stability and power supply quality of power grid.Therefore,through wind farm modeling and the simulation-software-based waveform analysis of systematic voltage and frequency under different operational modes,the maximum injection power of wind farm in power grid is approached and a simple analytic method offered.It is concluded that systematic node voltage and frequency fluctuate with varied injection power of wind farm,and the frequency is more likely to fluctuate beyond systematic stability limits;the simulation model built by power system computer aided design(PSCAD) can simulate diversified dynamic processes of network better,approximates to the real system more than those built by MATLAB,etc,and is fit for the study on problems concerning wind farms.
