Control of hybrid renewable systems and their integration to the grid
Renewable energy systems connected to isolated grids and microgrids usually comprise several energy resources (wind, photovoltaics, etc.) and storage devices (electrolyzers, supercapacitors). These system components are coupled by means of power electronic devices, which play a fundamental role in the integration of the system to the grid. Sliding mode control offers a very attractive, simple and high-performance option to control the electronic converters. We investigate novel system topologies and control strategies to maximize renewable production of electricity and hydrogen while minimizing the impact on the grid power quality and fulfilling the inherent restrictions of devices operation.
