This paper presents a Model Predictive Control (MPC) MPPT technique. Extracting the maximum power from PV systems has been widely investigated within the literature; the main contribution of this paper is improvement of the Perturb and Observe (P&O) method through a fixed step predictive control under measured fast solar radiation variation. The proposed predictive control to achieve Maximum Power Point (MPP) speeds up the control loop since it predicts error before the switching signal is applied to the flyback DC/DC converter. Comparing the developed technique to the conventional P&O method indicates significant improvement in PV system performance. The proposed MPC-MPPT technique for a flyback converter is implemented using the dSpace CP 1103.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120913329","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}

However, additional analysis on the results in an external program is commonly necessitated for a variety of applications. This requires importing and managing the resulting data into an external platform, increasing user effort and rendering the process cumbersome. One of the capabilities of commercial software is an automation server which allows the software to be directly interfaced with an external processing program. This enables automatic retrieval of data without the need to maintain a database manually. This automation would allow for more straightforward algorithms and freedom in design, motivating more innovative data-driven methods with the use of multiple programs in a single environment. In this paper, we will discuss the generic capabilities of such automation servers, their setup, and explore the development of a simulation-based fault location algorithm applying this technique and the subsequent results.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129240187","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}

Understanding the impacts associated with renewable energy penetration are vital for future network planning and operation. Using probabilistic uncertainty models for power injections of these resources, this paper uses their statistical distribution to determine corresponding distributions for network state variables. The Jacobian linearization matrix is determined using the Newton-Raphson power flow method, and the statistical distributions of state variables at all buses in a network are obtained from a linear transformation of the injection distribution function. With these distributions, first and second moments of state variables in a given network can be approximated.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"69 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114102705","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 algorithm which is a combination of Slip mode frequency-shift (SMS) and reactive power versus frequency (Q-f) as active methods detects the islanding phenomena by forcing the DG lose its stable operation and drift the frequency out of the allowed normal range of the frequency relays. A simple passive islanding detection scheme that relies on frequency relays such as under/over frequency protection (UFP/OFP) would be sufficient to detect the moment of islanding. For demonstrating the performance of the proposed method, it is evaluated under the IEEE 1547, UL 1741 anti-islanding test configuration and multiple-DG operation. The studies reported in this paper are based on time-domain simulations in the MATLAB/Simulink. The proposed hybrid method detects islanding more efficiently for loads with high quality factor (Qf); also it operates accurately in condition of load switching and does not interfere with the power system operation during normal conditions. Simulation results prove that the proposed method decreases the time of islanding detection and has less Non Detection Zone in comparison to previous methods. In addition, the technique represents to be robust under multiple-DG operations.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132916485","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 widespread installation of PMUs across the power grid is gradually becoming a reality - and promises new capabilities to significantly improve real time knowledge of the power grid's operating state. Archived synchrophasor data provides a wealth of high-fidelity data to aid power system model sustainability analyses and to reconstruct unusual power system events. While the PMU device concept is well known in the power industry, the challenges of designing and implementing a PMU which integrates field measurements to deliver Global Positioning System (GPS) synchronized phasor data to the power industries' networks are not as well known or understood. This paper describes the steps, challenges, and reasoning involved in building a single-phase, distribution-level PMU. Our efforts have provided a fundamental understanding of a PMU's inner workings and direction to future efforts to improve PMU performance.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122406793","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}

One promising application of a second-life battery is stationary energy storage within a CERTS microgrid. This paper investigates the modeling of multiple paralleled traction battery packs within a CERTS microgrid, examining the impacts of elevated internal pack impedance on microgrid system operation. Impedance spectroscopy and hybrid-pulse power characterization are used to model vehicular Li-ion cells under a range of conditions that include second-life aging. The ac bus dynamics of the microgrid model are validated experimentally. Second-life battery models are incorporated into two CERTS microgrid architectures and system-level effects of changing the battery impedance are explored. Simulation results indicate that the modeled EV second-life batteries deliver promising performance characteristics in both CERTS microgrid architectures that were investigated.","PeriodicalId":352005,"journal":{"name":"2014 Power and Energy Conference at Illinois (PECI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131681972","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}
