摘　　要：This paper presents a theoretical study of damping,synchronizing and inertial control laws,implemented using controllable power injection devices like HVDC,FACTS or renewable-energy/storage systems which have power-electronic grid interfaces.The approach is to use a simplified dynamical model of a power system to arrive at generalized results regarding the effect of the strategies on the electro-mechanical dynamics of the system.These results are not dependent on the size,network topology and operating condition of the power system.This paper presents a differential-algebraic formulation and generalized eigenvalue analysis to facilitate a unified study of the effects of the control laws on the electro-mechanical modes.The damping,synchronizing and inertial control laws can themselves be extended to include the possibility of mutualdamping,synchronizing and inertial effects when multiple devices are present.The control laws are not only simple and intuitive,but also are found to have a predictable and generally beneficial impact on the electro-mechanical dynamics of the grid,even when detailed models are considered.
