Damping-enhanced virtual inertia control and parameter optimization for full-sized converter pumped storage units
摘要
Abstract
Full-sized converter pumped storage units represent one of the main development directions for future pumped storage systems.However,such units are unable to provide inherent inertia support to the power system.Conventional virtual inertia control methods suffer from issues such as weak damping,unsmooth frequency transients,and limited capability in eliminating steady-state frequency deviation.To enhance system inertia margin and frequency security,an improved virtual inertia control strategy for full-sized converter pumped storage units is proposed.The proposed approach introduces a Lead module to mitigate the negative damping inherent in conventional control schemes.A smoothing factor is adopted to replace the conventional deadband,resulting in smoother frequency transitions.Additionally,an Anti-Windup integral module combined with a Washout filter is employed to suppress steady-state frequency deviation issues present in conventional methods.Moreover,the tuning methods for the baseline control parameters are investigated,and the PID gains are optimized using a DOE-based ParEGO multi-objective algorithm.Finally,simulation studies on a system incorporating full-sized converter pumped storage units demonstrate that the proposed strategy provides effective frequency support and improves system frequency stability.关键词
