Abstract

Large-scale wind turbines are integrated into the grid, causing the short-circuit ratio to decrease. This also weakens the ability to regulate voltage, and faults can more easily lead to greater voltage fluctuations during renewable energy unit and off-grid accidents. A synchronization configuration method that considers improving the short-circuit ratio is studied for power grids with a high proportion of wind power. First, an analysis is conducted on the multi-renewable-station short-circuit ratio/multi-renewable-station short-circuit ratio (MRSCR), which can explain interactions among sites. Second, system security constraints are used to develop an ideal synchronous generator power flow control model based on the power grid topology. Next, the Beetle Swarm Optimization/Beetle Swarm Optimization (BSO) algorithm is used to determine the ideal MRSCR. This produces the best voltage and power settings for synchronous generators. Finally, a case study is carried out on a power grid with a high proportion of wind power to verify that the proposed optimization method can significantly improve the MRSCR of wind turbines based on PSD-BPA.
