Advantages of CVR deployment in distributed energy resource (DER) integrated system are quite substantial due to the power transfer from various locations to the sinks/loads. However, due to the stochastic nature of photovoltaic (PV)/wind based DERs and loads, benefits of CVR might vary from time to time. This paper demonstrates the use of the Analytical Hierarchy Process (AHP) to measure the benefits of CVR at different time instances by estimating the CVR factors, the voltage sensitivity factors, and the loss factor considering load and PV uncertainty. This analysis gives flexibility to the utilities to decide on the timing on CVR arrangements in a specific distribution feeder and good knowledge about CVR benefits for a chosen feeder. Beta and normal distributions are used for solar and load uncertainty modeling, respectively. In addition, the paper provides a probabilistic analysis on the predictive CVR-off operational voltage during the CVR deployment time for approximate estimation of the factors. An existing distribution feeder in Duke Energy's service territory is used to conduct a time-series analysis for analyzing the results.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124857395","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 design is to comply with a national effort known as the SunShot initiative which aims to leverage the awareness of renewable resources, particularly PV generation systems. The experimental set for this design includes a PV panel, an inverter, a typical load, two MyDAQs as the data acquisition system, a laptop to run the LabVIEW program, and a 32\" TV monitor to display the results. To be suitable for educational purposes, the system is designed to show three aspects of the system: pollution reduction rate, power conversion process, and the axillary services that a real PV generation system can offer to the grid. This paper particularly presents three objectives: 1) design the PV-powered cart, 2) analyze the pollution reduction capability, and 3) estimate the amount of reactive power available to be delivered to the grid. The specifications of the materials used for this design are presented along with the developed program used under Lab VIEW to visualize those aspects. The impact of this design on leveraging the awareness of PV generation system is significant, particularly for the next generation workforce of the power industry.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123259871","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}

Particularly, during close-in external fault, current transformer (CT) saturation creates high operating current which can cause mal-operation of differential relays. As a result, a fault discriminator is necessary to supervise the differential schemes to prevent undesired tripping operation. Most of the existing fault discrimination algorithms have been proven as an efficient external fault detector; however, they suffer from lack of sensitivity to high impedance internal faults. This paper presents a comparative analysis on sensitivity of three existing fault discrimination algorithms including Phase Angle Comparison Algorithm (PACA), Rate of Change of Differential Algorithm (ROCODA), and Alienation Coefficient Algorithm (ACA). Fault simulations were performed using a three-bus test system. The results documented in this paper show that the degree of sensitivity of ROCODA and ACA are similar and much higher than PACA. The comparative analysis presented in this paper can be employed as a useful guideline for selection of an appropriate protection scheme for busbar systems.","PeriodicalId":296428,"journal":{"name":"2017 North American Power Symposium (NAPS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121749716","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}
