With wind power integrated into the power system on a large scale, the system has become vulnerable to the frequency stability issue. The battery energy storage system (BESS) is considered the key solution to improving the system frequency regulation performance due to its fast response ability.. This paper proposes an innovative primary frequency regulation control strategy for wind power and hybrid energy storage systems. First, a mathematical model of the wind–hybrid energy storage integrated system is established. By introducing a state of charge (SOC) indicator, a power allocation. . Abstract: The doubly-fed induction generator (DFIG) uses the rotor's kinetic energy to provide inertial response for the power system. On this basis, this paper proposes an improved torque limit control (ITLC) strategy for the purpose of exploiting the potential of DFIGs' inertial response.
