At the same time, it also offers a good power sharing among the distributed generations (DGs) when the load-rated power is changed but maintains the DGs power supplies. This self-frequency restoration control is different from the conventional droop where it includes the frequency limitation condition in order to have fast frequency restoration during load changes and to ensure an accurate active and reactive power sharing. The proposed controller has been tested with two different power rating of DGs with the load during off grid condition. A simulation study has shown the effectiveness of the proposed controller when the DG units are in plug-in/-out and under load circumstances for autonomous microgrid condition. The simulation results have exhibited the performance and robustness of the proposed controller method for ...

The improved controller has been combined with the existing MPPT algorithm. Currently, the existing CVC has some drawback as it produces an unnecessary shoot-through signal period which caused the capacitor voltage at ZSI not to be constantly maintained. Therefore, the modified algorithm has been included by a deviation of the shoot-through duty cycle. It is to enhance the existing CVC performance and increase the effectiveness of the whole PV generation whenever the input PV irradiation is changed. At the same time, it is also able to maintain a constant dc-link voltage at ZSI. This proposed control algorithm has been verified throughout simulation tests using linear and non-linear loads by observing the constant dc-link capacitor voltage. This proposed controller has also been compared to the conventional CVC with the same load ...
