Dynamic Performance of Non-Minimum-Phase Zeros-Dominated Power-Synchronization Control
In this letter, it is found that non-minimum-phase zeros of power-synchronization control (PSC), induced by q-axis current injection, only dominate the system in weak grids, with one exception of low converter voltage magnitude. Using Bode's gain/phase relation, a trade-off analytical condition between the bandwidth and phase margin is proposed considering the locations of right-half-plant (RHP) zeros. System dynamic performance is improved compared to the design ignoring the effect of RHP zeros.
期刊介绍：
The scope of IEEE Transactions on Power Systems covers the education, analysis, operation, planning, and economics of electric generation, transmission, and distribution systems for general industrial, commercial, public, and domestic consumption, including the interaction with multi-energy carriers. The focus of this transactions is the power system from a systems viewpoint instead of components of the system. It has five (5) key areas within its scope with several technical topics within each area. These areas are: (1) Power Engineering Education, (2) Power System Analysis, Computing, and Economics, (3) Power System Dynamic Performance, (4) Power System Operations, and (5) Power System Planning and Implementation.
