Study On Comprehensive Evaluation And Structure Optimization Of Marine Renewable Energy Exploiture

Energy is an important foundation for economic and social development. In recent years, with the continuous development of economy and the rapid growth in energy demand, the mass consumption of fossil fuels and other non-renewable energy not only bring the problem of energy shortage, but also caused increasingly prominent problems of environmental pollution and climate change. Renewable energy sources, such as the abundant marine renewable energy, are clean, non-pollution and sustainable. Therefore, strengthening the exploiture of the renewable energy, especially marine renewable energy is the only way to achieve sustainable development.Firstly, the status and trend of marine renewable energy exploiture are summarized and evaluation index system of marine renewable energy exploiture is built from five aspects, technology, economy, resource, environment and security according to the characteristics of different marine renewable energy. On this basis, the paper proposes the comprehensive evaluation method which includes fuzzy analytic hierarchy process, index assignment and data normalization. Then the mathematical optimization model of renewable energy exploiture and the model of non-renewable energy exploiture are constructed respectively for the purpose of studying the problem of the structural optimization of marine renewable energy exploiture.Then, the paper takes an empirical study of comprehensive evaluation of marine renewable energy exploiture in Dalian. Marine wind energy exploiture in Dalian is analyzed by the proposed evaluation index system and method. The importance order of the influencing factors of marine wind energy exploiture in Dalian is determined and the suggestions of marine wind energy exploiture in Dalian are proposed. On the basis of the analysis of the energy supply and demand situation and marine function zoning in Dalian, the comprehensive evaluation score of the exploiture of renewable energy and non-renewable energy are obtain by the proposed index assignment and data normalization.At last, the paper takes an empirical study of structure optimization of marine renewable energy exploiture in Dalian. According to the proposed evaluation method and mathematical optimization model, the mathematical model of renewable energy exploiture and the model of non-renewable energy exploiture in Dalian are constructed. The logistics optimization software CPLEX is used to solve the model and the optimal ratio of various energy exploiture of Dalian’s in2020and2030are acquired. At the same time, the paper reveals the optimal exploiture proportion and electricity generation of marine renewable energy in Dalian. The results can play an important directive role in regulating development planning of marine renewable energy in the future and policy making of energy industry in Dalian.
