Summary:Complementary use of multiple renewable resources, including wind, solar, and wave power, is the critical approach to improving the utilization of marine energy. However, the varying characteristics of each energy resource will significantly impact the stability and power generation ability of the complementary system, and few studies have focused on the complementarity characteristics assessment when integrating these three resources. Therefore, this paper creatively assesses the complementarity characteristics of wind-photovoltaics (PV)-wave system for producing more stable and adequate power for the renewable energy generation system (REGS). First, the fluctuation variation coefficient is proposed to quantify the output fluctuation more comprehensively. Second, the complementary potential among the three resources is analyzed based on Kendall's correlation coefficient to verify the integration feasibility of wind-PV-wave power. Then the complementarity characteristics of wind-PV-wave systems are further assessed based on the proposed fluctuation coefficient and their combined capacity factor. The assessment results show that, with a correct capacity configuration, the integration of wind-PV-wave has a better performance of obtaining more stable and adequate power than conventional complementary types. Finally, a dual-objective optimal method is proposed to determine the optimal capacity configuration for wind-PV-wave system with optimal stability and power generation.
