The topology of the direct-drive wind power generation systems connected to the weak power grid is illustrated in Fig. 1, including the wind turbine, Permanent Magnet Synchronous Generator (PMSG), machine-side converter (MSC), DC capacitor, grid-side converter (GSC), filter inductors, and the AC power grid.
The interaction between the direct-drive wind power generation system and the weak grid involves multiple time scales with overlapping interactions. The main reason for instability is that the introduction of loops 2 and 3 by the weak grid reduces the bandwidth of the current loop, causing frequency band overlap.
The GSC of direct-drive wind power generation systems typically uses the conventional stationary coordinate system. The open-loop transfer function of the PLL is (6) H PLL (s) = (k ppll + k ipll s) 1 s Where kppll and kipll are the proportional and integral parameters of the PI controller in the PLL, respectively.
Key control loops affecting stability are identified, and a targeted parameter design process is proposed to enhance overall system performance. The interaction between wind power generation systems and weak power grids can easily lead to system instability, characterized by multiple-time-scales dynamics.
Two identical permanent magnet synchronous motors are used to simulate the wind turbine and generator, with the two machines connected via a drive shaft. The two motors are controlled by the RTU-BOX204 digital controller.
Reference [,, ] optimized the layout and control strategies for wind power systems using various methods; however, these works primarily focus on stability issues within the low- or mid-frequency range, limiting their ability to comprehensively address instability phenomena in the high-frequency range.
