Description

Technical Field

[0001] The present invention relates to the technical field of renewable energy collection, and particularly to an evaluation method, system and device for renewable energy resources. Background Art

[0002] Tidal energy is the energy generated by the natural tidal movements on the earth. It belongs to a kind of renewable energy. Compared with traditional fossil fuels, tidal energy does not consume the earth's resources and does not produce greenhouse gases and air pollutants. As a renewable energy, tidal energy has the characteristics of being stable and reliable, having a high energy density, and integrating with the marine environment. Nowadays, with the development and application of renewable energy, tidal energy, as a unique energy resource, has attracted more and more attention. How to efficiently collect tidal energy has become a top priority. Therefore, an evaluation method, system and device for renewable energy resources have emerged as the times require;

[0003] In the current technology, the selection of the installation location and parameters of tidal energy collection devices often depends on experience and intuition, lacking scientific analysis and quantitative basis. This makes the selection results may be subjective and inaccurate, unable to fully exploit the potential of tidal energy resources. Obviously, this collection method has at least the following problems:

[0004] 1. In the prior art, the installation location of tidal energy collection devices is often obtained through past experience and personal observation. This may lead to different views on the installation location of tidal energy collection devices among different people, lacking objectivity and consistency, and lacking comprehensiveness and accuracy. This may lead to an insufficiently comprehensive and in-depth understanding of tidal energy resources and environmental factors, thus affecting the judgment of the installation location, making it difficult to conduct scientific analysis and accurate judgment, and thus may lead to uncertainty and risks;

[0005] 2. At the same time, the prior art cannot consider the economic benefits of power generation types. Investors will have difficulty determining the return on investment, which may lead to difficulty for investors to make wise decisions, thus affecting the feasibility of power generation projects. It may cause decision-makers to be unable to determine the best power generation plan, and may lead to the inability of some power generation projects to continue in the long-term operation, thus having an adverse impact on the regional energy supply and economic development. Economic benefit is an important indicator for evaluating the feasibility of power generation projects. If it cannot be judged based on the economic benefits of each power generation type, accurate cost-benefit analysis cannot be carried out, which may lead to waste of resources and unnecessary economic losses. Summary of the Invention

[0073] It should be noted that economic feasibility refers to whether economic benefits and returns can be achieved when investing in, constructing, and operating a tidal power generation project.
