Research on the adaptability of power system considering the scale of large-scale wind power consumption

Inhalt:
Through the method of system hierarchical modeling, the analysis and evaluation method of system adaptability after large-scale wind power integration is deeply studied. Starting from the analysis of four different levels of random production simulation, unit maintenance plan, peak shaving, and frequency regulation, according to the change characteristics of load, wind power, power grid and power supply under different time scales, the system after the largescale wind farm is connected is given. Reliability index, annual maintenance plan and unit commitment, and focused on the calculation method of wind power curtailment at the peak and frequency regulation level and the overall wind power consumption scale. The above analysis method is applied to the Northwest Power Grid's 2020 main network planning plan, and the results obtained show that the method in this paper can provide a useful idea for planners.
