As the power transmission hub, the stability of the DC-link voltage plays a key role in the normal operation of the whole system, which affects the stable operation of the back-stage inverters as well as the normal power supply of connected loads. The stability problem in DC-link may occur at the low frequency, if the impedance characteristic of DAB as a source is incompatible with the impedance characteristic of back-stage converters, which will be investigated in this paper. Seen from common DC-link, the impedance of DAB, DC/DC and DC/AC converters on this side are modeled. Based on the model, the mechanism and main contributor of low-frequency oscillation in DC-link are presented. The derived impedance model in the frequency domain and the result of stability analysis are verified by the simulation.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117064828","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 NC array is positioned at either of two sites of the cell, namely at the back contact layer wrapped by transparent electrode and at the absorber layer. The comparative analysis is performed for light absorption enhancement as well as transparency for different NC sizes and NC distances along with various composition of the perovskite material at a fixed absorber thickness. With the investigation of local field concentration and extinction cross-section of the NCs as well as the absorption pattern of the cell for both NC locations it is found that, for both cases the enhancement is achieved by red shifting the band edge. However, higher absorption enhancement can be obtained for cells with plamonic NCs at back contact which is more pronounced for smaller NC size, attributed by the strong electrode coupling effect. In contrast, cells with NCs at the absorber is found to provide better transparency at a fair level of absorption enhancement. Thus, this work provides a comprehensive optical analysis of typical perovskite solar cells with the incorporation of plasmonic metal nanostructures.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125928252","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 solve this problem, a SOC equalization control strategy is proposed. The method utilizes the state of charge of the energy storage unit and the change rate of voltage as information carriers. Each energy storage unit can adaptively adjust the equivalent output impedance of itself without a communication network to transmit information. Firstly, the underlying control is transplanted into the distributed energy storage control system, and the equalization algorithm based on the state of charge is embedded into the zero-return controller. Secondly, in order to control the speed of charge state equilibrium, the rate factor is added to the algorithm. Then, the equivalent model of DC microgrid is established, and the comprehensive principle of power allocation for distributed energy storage system is proposed, and the condition with AC component is also discussed. Finally, the effectiveness of the proposed strategy is analyzed by Matlab/Simulink simulation.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125573415","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 ease the pressure of the power system and balance supply and demand in the peak periods, we devise an integrated demand response (IDR) program by taking different types of consumers into consideration. Different from most of the existing works that model the responsive demand without classification, we classify consumers into different clusters using the method of k-means. Based on the classification result, the responsive demand models are obtained through historical data. The proposed IDR program is modeled as a nonlinear programming problem. By establishing the Karush-Kuhn-Tucker conditions, the closed-form optimal energy scheduling strategy is given. Moreover, we design an incentive pricing mechanism from which utility company can make optimal decisions. Simulations validate that the proposed IDR can solve the problem of the imbalance between supply and demand in the peak periods and the total costs of utility company can be reduced by implementing different incentive prices for different clusters of consumers.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115529643","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}
