摘要：

For islanded micro-grid consisting of the intermittent renewable energy sources with Diesel generator (DE) and battery energy storage system (BS), a novel frequency hierarchical control scheme is presented with the frequency hierarchical control structure and the coordinated control strategy, which are suitable for different characteristics of DE and BS for improving the frequency stability and flexibility of islanded micro-grid. In the frequency primary control, a modified droop frequency control of BS is given to improve the transient frequency response and reduce frequency deviation by rejecting the fast, small and random net-load fluctuations. In the frequency secondary control, a modified PID control of DE governor is proposed to deal with the slow and big net-load fluctuations to achieve the zero steady-state error frequency control of islanded micro-grid. Finally, the performance of the proposed method is validated in the practical application to Dong'ao islanded wind-diesel-battery hybrid energy micro-grid operated under various conditions. ©, 2015, South China University of Technology.
