In order to improve the prediction accuracy of PV power when only irradiance and PV power data can be obtained, while other multi-source data such as temperature, precipitation and other meteorological data, are unavailable, the paper proposes a PV power prediction model based on data mining and the multi-kernel support vector machine (SVM). Firstly, the wavelet threshold denoising method is used to denoise the data of irradiance and PV power which contains many burrs and the large signal fluctuation. Then, the parameters are extracted by irradiance and power characteristic representation, which include six irradiance characteristic parameters and two power characteristic parameters. With the characteristic parameters, the similar days are selected by the data mining technology, a clustering algorithm using SOM and K-Means. Finally, the multi-kernel SVM is used for PV power prediction, where the multi-kernel function is used to deal with the distribution characteristics of data and improve the accuracy of PV power prediction. The experimental results show that the prediction accuracy can be improved by the wavelet threshold denoising and multi-kernel SVM. The high precision PV prediction results can also be obtained with the irradiance and PV power data only, and the PV prediction accuracy of multi-kernel SVM is higher than that of the single-kernel SVM and classical back propagation (BP) neural network.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"102 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113987699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of the coil radius and the number of turns on the transmission power and transmission efficiency i s a nalyzed by the method of simulation calculation. Considering the limitation of the resonant coil's turn-to-turn voltage on the system, the radius of the transmitting coil and the receiving coil are selected as 0.5m and 0.6m, the number of coil turns is 45 turns. The simulation results show that when the system is working with the above parameters, the load power of the system is 39.4W, and the transmission efficiency i s 5 9.4 %.

Especially industrial applications ask for high uptimes and a stable voltage supply, which are both at stake in a power grid dominated by renewable generation. DC-MGs overcome these drawbacks by balancing energy distribution and power demand locally. For the planning and design of these grids a systemic approach is needed, due to the fact that many components are interacting. The task arises of structuring the knowledge available for individual technologies in an overall design framework. For this purpose, current state-of-the-art design processes are discussed in this article. These processes are mapped into the context of the requirements in an industrial environment. The findings are transferred to the design of industrial DC networks. Finally, a complete design process for DC-MGs is derived, which is proposed as a basis for the development of tools.","PeriodicalId":153030,"journal":{"name":"2021 3rd International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121872817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
