Abstrak

When the voltage of the power grid is unbalanced, the DC transmission and distribution system using modular multilevel converters (MMC) as converter devices will encounter problems such as AC current asymmetry and secondary pulsation of active and reactive power. Therefore, a hybrid control strategy of passive based control (PBC) and sliding mode control (SMC) based on port controlled dissipative Hamiltonian with Dissipation (PCHD) model is proposed. A passive sliding mode variable structure controller for MMC control system under PCHD model is designed further. Through simulation, it is verified that the proposed method has better control performance than common methods such as PI control and passive control.
