Abstract
To address the stable power supply challenge posed by volatile, intermittent, and random renewable energy integration in wave-wind-solar-storage integrated power generation platforms with various installed capacity configurations and operation modes, three wave-wind-solar-storage integrated offshore platform topology circuits and power conversion networking technologies are proposed. A comprehensive simulation model, including wind, solar, wave, energy storage, and load is established. The system is tested under different operation modes and various disturbance conditions. The results show that the renewable energy are independently and efficiently converted, and the voltage and frequency are stabilized. The wave-wind-solar-storage integrated networking and modeling method provides an effective solution adaptable to various offshore power generation platform scenarios, effectively addressing the challenge of stable power supply for wave-wind-solar-storage power generation platforms. This method offers effective technical support for the integration of marine renewable energy, accommodating increasingly complex platform topologies, diversified power generation units, and hybrid converter technologies.
