Research on Analysis Method of Tidal Current Energy Resource Characteristics

Abstract In the demonstration and validation of tidal energy converters, analyzing the characteristics of tidal current energy resource in the demonstration sea area of tidal energy converters is a key step to evaluate the economic performance of the tested tidal energy converter.
 Based on analyzing the research status and the evaluation demands of economic performance indicators of tidal energy converters at home and abroad, the analysis method of tidal current energy resource assessment and characterization was studied, a method for calculating the cumulative frequency
 of tidal current velocity was proposed, and it was applied in the processing and analyzing the tidal current field test data. Moreover, using the analysis results of tidal current energy resource characteristics, the annual energy production of the tested tidal energy converter was calculated.
 The results show that the analysis method studied in this technical note can analyze the tidal current energy resource characteristics comprehensively and objectively, and the proposed calculation method of cumulative frequency can reflect the availability of the tidal energy converter in
 the demonstration sea area. The research results not only provide a reference for analyzing the tidal current energy resource characteristics in the demonstration sea area of tidal energy converters, but also provide a reference for calculating the annual energy production of tidal energy
 converters.
