Aiming at the problems of high investment and high risk in the traditional users’ self-purchase governance equipment, a service pattern for premium power supply based on trust lease is proposed. The specific content and implementation process of the pattern are proposed to solve the three problems of sensitive loads screening, service fees optimization and service fees allocation. By defining the \"capacity/loss ratio\" to screen out the sensitive loads which are necessary to install the governance equipment; optimize the service fees with the goal of maximizing the net revenues of the user and the service provider; establish the asymmetric Nash negotiation model of the service fees allocation between the power company and the equipment manufacturer, and propose the strategy of service fees allocation. So far, a complete and operable service pattern has been formed. Finally, an empirical analysis of a sensitive user proves the feasibility of trust lease pattern and provides a new pattern reference for the development of premium power supply service.","PeriodicalId":142509,"journal":{"name":"2022 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125082141","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}

VSI topology has dominated motor drive system for decades. Significant problems caused by drop-in replacement of WBG switches in VSIs were identified in previous studies. As an alternative solution, CSI shows greater compatibility with fast-switching WBG-based devices. Gallium Nitride (GaN) as one of most promising candidate in future power electronics field is selected for evaluation purpose in this work. Estimation of switching loss of VSI and CSI switches have been made based on tailored VSI and CSI DPT. In addition, the system efficiency comparison between GaN-based CSI and VSI is addressed. The LTspice is used as evaluation/simulation platform to examine the performance of VSI and CSI under high-frequency operation.","PeriodicalId":142509,"journal":{"name":"2022 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121097044","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 this paper, we establish the equivalent model of driving circuit considering parasitic parameters, and analyze the difference between the gate-source voltage and test voltage at different test points. Then, the influence of the driving circuit parameters and layout compactness on the test voltage error is quantitatively analyzed.

The PV operation data of supervisory control and data acquisition (SCADA) suffer from a high proportional of abnormality due to equipment failures and/or human activities. As a remedy, we present a novel outlier detection method, which leverages vine copulas for modeling the multivariate dependence of PV power output and different external environmental conditions. A generalized confidence interval (CI), obtained by quantile computation, is then utilized to give upper and lower thresholds for identifying outliers, which can be further optimized with the best selection of conditions. For algorithmic improvement, we combine the method with manual exclusion of three typical types of outliers in a priori.

Also, an active distribution network feeds electrical loads and plug-in hybrid electric vehicles. An optimal active and reactive power management strategy is imperative for a technically feasible and financially viable operation. The renewable sources are interfaced via power electronic voltage source converters, which can control the reactive power injection into the network. In this paper, a joint optimal active and reactive power control strategy is proposed, which utilizes the reactive power handling capability of the voltage source converters. Uncertainties of renewable generation, load demand, grid energy price, and charging load demand of the plug-in hybrid electric vehicles are modeled and incorporated using the probabilistic \"Hong's point estimate method\". A group of measures like optimal procurement of active and reactive power from available resources, optimal battery energy storage scheduling, demand response, smart transformer scheduling, and network reconfiguration are carried out to maximize the expected profit of the distribution network operator. The proposed method is validated by simulation studies on a thirty-three bus active distribution network.","PeriodicalId":142509,"journal":{"name":"2022 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133928237","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}

Inappropriate package method will restrict SiC power modules’ characteristics at high frequency and lead to lower efficiency as for several factors, such as electromagnetic interference problem caused by large parasitic capacitance, unbalanced current and overshoot voltage caused by parasitic inductance and thermal coupling. Thus, this article aims to comparatively explore the methods of integrating parallel double-sided power modules (stacked package and level package) in electrical and thermal fields. The research is based on 1.2-kV interleaved planar SiC power modules. Parasitic parameters are measured in two package modules, and switching performances are tested based on these parameters. Moreover, simulation results show that stacked package module has relatively better thermal and electrical performance than level package module.","PeriodicalId":142509,"journal":{"name":"2022 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130019698","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 nucleus of the proposed method lies in a developed algorithm that can identify the most influential random variables to the variation of TTC. As such, smoothing out the power fluctuations of the main contributors will reduce the variance of TTC most effectively.
