Hybrid renewable energy systems are gaining more attention for the problems like Global Warming and high CO2 emissions. Another topic that increases its popularity is hydrogen. Because it is a very good alternative fuel. In this work, every component of a basic Hybrid Renewable Energy System (HRES) will be modeled and short-time simulations will be made for any transient response of individual components. MATLAB Simulink is used for every model and simulation. HRES includes a wind turbine, PV array, battery energy storage, and electrolyzer. The system is also grid-connected. Additionally, different control strategies are investigated, obtained, and created. Maximum Power Point Tracking (MPPT) algorithms for Wind Energy Conversion System (WECS) and PV array were conducted. A control algorithm that combines the battery and the PV array was made and necessary circuits were designed. An overall model for different sizes and operations is created. One-day-long simulations were made for 11 different cases. The user can alter the overall model for different turbines, PV modules, and battery sizes. The total amount of hydrogen produced, energy generation, and consumption were observed for every case.

The necessity of renewables is increasing day by day due to increasing energy demand. Therefore, novel approaches and methods for producing electricity in an environmentally friendly manner are valuable and critical. The seas have enormous potential in terms of wind, waves, solar, and hydrogen systems. The study presents the investigation of the potential dynamics for energy island formation on T & uuml;rkiye borders. Also, targets, legislation, and environmental and social concerns are discussed comprehensively. Results show that offshore wind and hydrogen are promising systems shortly while solar and wave energy needs more research for T & uuml;rkiye. The Marmara and Aegean Seas are considered technically feasible for offshore wind installations, while the Mediterranean and Aegean Seas have the highest technical solar potential. In addition, the highest wave power is detected along the line from I(center dot)zmir to Antalya Coast while hydrogen energy systems receive great interest with academic and industrial projects in the Marmara Coastline. Profiting from marine energy, marine spatial planning, and grid availability are detected as the shortcoming issues in T & uuml;rkiye. The study could give critical information to energy planners, and decision makers for potential projects.
