Novel control method of voltage source converter and synchronous generator to frequency control in a microgrid

Now days using of distributed generations (DG) are growing. Without considering appropriate controller, their operation is not useful and efficiency. DG has less impact on the network frequency than synchronous generator (SG) due to its low inertia compared to SG. DGs using power electronic converters are connected to low-voltage networks, so that converters work in voltage control mode and power control mode.In this paper, a new control method to investigate the role of participatory voltage source converters with synchronous machine to frequency control of the microgrid has been presented. In this regard, the cascaded frequency-angle loop control with adaptive nonlinear controller in order to power sharing and frequency control is used. In the following, new algorithm for evaluating the effects of VSCs with synchronous generator is presented. Finally, the accuracy and authenticity of the proposed method, using simulations used in software Simulink Matlab evaluated and approved.
