Hybrid Synchronous Control Based Voltage Unbalance Compensation Strategy

As the penetration of distributed energy sources is increasing, the stability pattern of the power systems becomes more complex, and they also face the risk of desynchronization and harmonic disturbances when facing large disturbances or asymmetric operating conditions. It is important to analyze and improve the flexible interconnected system to maintain the symmetric and stable operation of voltage even under large asymmetric disturbances. This article proposes a kind of voltage unbalance compensation theory with hybrid synchronous control, construct a voltage unbalance compensation model in accordance with the reactive power compensation principle, and then proves the validity of the suggested control approach through simulation.
