Abstract

[...]the aforementioned power pulses still propagate into the power grid through the power converter which could lead into instabilities in the grid [11,12,13]. [...]energy storage systems (ESS) that can absorb power fluctuation and thereby ensure smooth power delivery to the grid are becoming an integral part of WEC systems. The grid connected converter of the OWC WEC system should adhere to all these grid codes. According to [21,32], MPC controllers are not only simpler than voltage oriented control (VOC)-based pulse width modulators (PWMs) but can also accurately track the reference value by generating the optimum switching signal. [...]the proposed battery direct-connection method and the control technology are able to deliver smooth power output to the grid without going into unstable conditions under varying input power conditions.
