摘要：
Multiphase energy conversion systems have been recently proposed for motoring and generating applications where bidirectional power flow is required. When such multiphase systems are connected to the grid (e.g., in multimegawatt wind energy systems), efficiency is maximized by operating the system in a balanced manner with an equal distribution of the power among phases. However, the situation differs when the multiphase system is connected to different microgrids with individual active and reactive power requirements. In this scenario, an unequal power sharing between the different phases of the multiphase machine becomesmandatory. This story explores the control strategy to operate in speed mode with an independent regulation of the power contribution to the microgrids. Experimental results confirm the capability of the system to satisfactorily operate in unbalanced mode both in steady-state and transient conditions, thus providing the flexibility to divert the power from one three-phase winding to the other with no impact on the system dynamics.
