In the grid side, energy storage can participate in safety accident response, power grid frequency control, peak shaving, power grid upgrading delay and easing transmission line congestion, etc. In the power supply side it is mainly used to improve the power supply flexibility and controllability; In the user side it is mainly used to improve power quality, arbitrage through peak valley, as well as providing uninterrupted power supply to ensure reliability. Due to different application conditions and purpose under different scenarios, energy storage configuration requirements are also vary. So it leads to various configuration method and lack of a unified evaluation index. In this paper, the existing optimization configuration method their respective advantages and disadvantages are analyzed, and then, the ideas, principles and basic evaluation index in common scenario are summarized. It provides reference basis for energy storage optimization in power system.","PeriodicalId":11264,"journal":{"name":"DEStech Transactions on Engineering and Technology Research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89805641","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}

This method refers to punctuated-equilibrium Model (PEM) which is a pattern of group development in organizational behavior. PEM uses the long-term equilibrium phase and the short-term abrupt phase to solve the problem of group stagnation. The present work mathematically modelled this alternating process. The efficiency of the proposed PEPSO was evaluated using CEC 2014 benchmark functions. The experiments showed that PEPSO could solve premature convergence and had more good convergence accuracy than PSO on some test functions. Furthermore, it was also confirmed that the swarm was divided into different groups and the individuals of every group almost acted in unison. This provides a good explanation between PSO and organizational behavior from a new experimental perspective.","PeriodicalId":11264,"journal":{"name":"DEStech Transactions on Engineering and Technology Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90907151","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}

In order to reduce the influences, an optimal allocation method of energy storage considering probability distribution of new energy fluctuation is proposed. The probability distribution characteristics of different time-scale power fluctuations of new energy power are obtained by probability statistics. According to the probability distribution characteristics and fluctuation index, a probability indicator calculation model which contains time-scale and fluctuation amplitude is set up. The model is then solved by iterative calculations to get minimum compensation power of the required energy storage. Thus, its rated power, capacity and initial state of charge are calculated. This method only compensates the fluctuated power that does not meet the fluctuation index, and has no impact on the power already satisfied. Through calculation and analysis using the data measured from a 50MW photovoltaic power station, the method is proved to be correct and effective.","PeriodicalId":11264,"journal":{"name":"DEStech Transactions on Engineering and Technology Research","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78455050","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 microstructure and field emission properties of the CNTs grown by three different metal substrates are researched. The results show that the CNTs grown on the high-voltage aluminum alloy substrate have optimal field emission properties. The turn-on electric field and threshold electric field is 0.92 V/μm and 2.58 V/μm respectively and the field enhancement factor is 20930. Lastly, the field emission current stability of the CNTs is tested, finding the field emission current of the CNTs grown on the high-voltage aluminum alloy substrate is the stablest.

Then, based on the stiffness formula, the optimization design model with geometric configuration parameters was constructed, and the optimization design model was applied to a lens with a diameter of 400mm.

Identifying all the pollen species present on earth, and more particularly in a territory, is a major concern for palynologists. This is an arduous task that can be automated using artificial intelligence. Many studies have tried to solve this problem by using machine learning and deep learning. In this paper, we present three pollen recognition approaches: Classification with no examples, recognition with a sufficient number of examples, recognition with un-sufficient number of examples. For each of them, we propose respectively to use Visual Bag of Word and expectation-maximization clustering algorithms, Classification using Local Binary patterns and the Gabor Filter Feature, Local Binary Patterns and Prototypical Networks. We find 77,38% recognition for 10 pollen species rate for the first one, 90.80 % for training with a sufficient number of examples and 80 species, and 20 different pollen species and finally 84,30% for the third approach with one example for training and 20 species.","PeriodicalId":11264,"journal":{"name":"DEStech Transactions on Engineering and Technology Research","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86953945","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}
