Abstract According to the situation that the power system can only defence the fault passively, the paper offer an new FACTS device named energy storage power modulation system(ESPMS). This device, which employed new technologies such as AC excitation, VSCF and vector control, combines the flywheel power storage with the traditional phase synchronization technology. ESPMS can modulate phase, store and generate energy, which can stabilize power system actively. This paper also shows detailed discussion about the control strategy and method of flexible power conditioner(FPC) which is the core equipment of ESPMS and analysis referring to several key problems about system realization. Initial results reflect that this device can quickly and enormously modulate the active power and reactive power in four-quadrant, which makes power system stability possible.
