Summary:Nowadays, the inertia of the power system is decreasing as the penetration rate of the distributed energy resources such as wind power and photovoltaic and the proportion of the converter is raising, which means the power system is no longer available to provide sufficient reliable frequency support when disturbance occurs. In order to solve this problem, the main method is to utilize the fast active power response feature of the bidirectional modular multilevel converter (MMC) to compensate the active power shortage, which advances high requirements for the rapidity and the reliability of the power conversion performance of bidirectional MMC. Therefore, this paper establishes a bidirectional MMC model in MATLAB Simulink through mathematical modelling and a simulation to evaluate the reliability of the MMC's fast active power response is carried out.
