| Our country is a great ocean state having rich marine resources,but the use of the ocean is not much.A large number of fossil fuels are being used and gradually face failure,but the renewable energy which mainly includes wind energy and solar energy has few types and less power than fossil energy,so that renewable energy is still not completely replace fossil fuels so far.If we can make resources more use which are rich in content,diverse and widely distributed,whether for the world or China,the prospects will be great.In order to improve the efficiency to obtain more energy,the concept of array-type wave power generation systems is proposed,and the combination of several float arrays is more efficient extracting a wave energy than a single float and the output energy is more stable.But the energy is different in different composition of the float array.Therefore,the position of each float is required to be calculated so that the efficiency of extracting the wave energy is the highest.There are many kinds of optimization algorithms and the differential evolution algorithm is used in this paper to optimize the float array of wave power generation system because of its strong global search ability and simple algorithm.The optimal design of the arrayed wave power generation system is mainly carried out from the following aspects:(1)The background and significance of the topic are expounded,and the research process of the wave energy generating device at home and abroad is summarized.The characteristics and research course of the array-type wave power generation system are briefly introduced.(2)The hydrodynamic modeling of the wave energy conversion(WEC)device is used to analyze the parameters of the array and the relevant calculation method is given.(3)The differential evolution(DE)is studied and improved,and the improved differential evolution algorithm is used to optimize the array. |
