On sizing and control of a renewables-based hybrid power supply system for stand-alone applications in an island context

Abstract : This PhD thesis models a renewable-based hybrid power supply system applied in an islanded context and investigates sizing and regulation strategies of such a hybrid system. First, various marine energy production technologies were reviewed and compared to common renewable resources. As well, various energy storage technologies were reviewed, compared, and evaluated to fit the chosen site characteristics. A brief investigation on offshore energy transmission and inverter regulations methods is presented. Then, a study of the site characteristics, and the availability of the different renewable energy resources in the area are presented. This energy study constitutes the basis of the proposed system sizing method, where minimizing the cost and the CO2 emissions are considered as the main objectives. Furthermore, a fuzzy logic power management approach is proposed for the islanded microgrid. Finally, a detailed study of the system components grid-side inverter regulation is presented. Three regulation levels were investigated: the single inverter, the renewable farm, and the hybrid system. In this context, different regulation strategies are considered at each level.
