This paper proposes a new method for enhancing the dynamic stability enhancement of a hybrid wave and
photovoltaic(PV) power generation system integrated into a distribution power grid. The wave power generation system
(WPGS) is simulated by a linear permanent magnet generator (LPMG) driven by an Archimedes wave swing (AWS). The
output of the WPGS and the PV system are connected to a common DC-link through a voltage-source converter(VSC)
and a DC/DC boost converter, respectively. The common DC-link is interfaced to the distribution power grid via a
voltage-source inverter (VSI). A super-capacitor (SC) is utilized to smooth the generated power delivered to the
distribution power grid. The proposed control scheme to maintain stable operation of the system while achieving
maximum power extraction for the wave system and the PV system is test in matlab environment and results are
compared with conventional controller.
