This is motivated by NERC TPL-001-4 for analyzing N-1-1 contingency events. In this paper a new reliability analysis technique is developed. Referred to as a Risk-Based Reliability Method (RBRM), it is applied to a 68-bus, 16-machine IEEE benchmark to evaluate system reliability under N-1-1 analysis. Factors include the transmission line age, load flow under normal conditions and load flow under post-first-disturbance conditions. Results are also included where reliability factors are modified in order to improve the ability to identify and rank the most severe and highly probable contingencies.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114155990","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}

By expressing the Signal-to-Noise Ratio (SNR) of the angle signal and the derived frequency signals in terms of correlation functions, the asymptotic behavior of numerical derivatives are studied. This provides insight as to how the derivative operation will potentially damage noise-corrupted PMU data to be analyzed by a mode meter. In particular the commonly used first order backwards difference (the `diff' function in MATLAB), the first order central difference, the second order backwards difference, and an angle differencing approach are studied. Data measured from PMUs in the WECC system are analyzed as are data simulated form a reduced-order model of the WECC system in order to better understand the correlation-based SNR expressions. The results presented herein provide a framework for the incorporation of measurement noise effects in mode meter algorithm performance and certification studies, and can provide a theoretical basis for the selection of a derivative filter for use in the preprocessing step of a mode meter algorithm.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117083531","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 novelty of this converter is that time-stamped grid voltage angle received via network communication channels has been used to synchronize the converter to the grid. Therefore, all grid-tied converters in a microgrid with this development will not require line voltage sensing and phase-locked loops. The power section and modulation was built on a CompactRIO 9064 that also had a GPS timesource. In a larger power system, a nearby PMU can be used for the time source. A PMU capable controller is placed at the point of common coupling to measure the electrical angle of the microgrid. The electrical angle is time stamped with GPS time and communicated to the power converter which is then used for grid synchronization. This paper presents the results obtained during operation of the PMU capable converter in both rectifying mode and inversion mode.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130555436","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}

Recent studies show that adversaries can not only generate attack vectors, which can bypass the conventional detector, but can also optimize the attack vector to compromise least number of sensors. We examined four types of attack in state estimation process. Then, we examined least effort false data injection attack on how to find the optimal attack vector. Based on the analysis, we implement χ2 detector and Euclidean distance detector to detect attacks. We propose an effective way to protect power system sensors. The case studies are based on a 5-bus system and IEEE-14 bus system. It shows that least effort attack can make most significant deviation of state estimation by compromising least number of sensors. χ2 detector can detect random data injection, bad data injection and DoS attack. However, false data injection can bypass conventional statistical detector, such as χ2 detector. Euclidean distance detector can detect false data injection.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127602220","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}

We assume that voltage regulation market is a separate but complementary market to existing energy markets (day-ahead and real time markets). An independent system operator (ISO) will decide when the voltage regulation market is to be launched. ISO will determine the required voltages (in p.u) at some nodes and clear the market based on the submitted bids and offers by the voltage service providers. ISO can anticipate the low-voltage situation ex-ante at some locations and can initiate the voltage regulation market. The voltage regulation market problem was formulated as nonlinear AC-OPF model and was solved using improved differential evolutionary algorithm. We used an IEEE 14 bus system as a test system in which the voltage regulation market clears. We showed that the development of voltage regulation market is of practically possible and can improve both social welfare and system condition.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128078439","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 issue is becoming more severe as the penetration of wind generation is increasing. As a result, wind generation is commonly subject to specific regulations which limit generation fluctuations. Three methods of reducing wind generation fluctuation are investigated in this paper from an economic perspective, including (a) dumping the wind generation, (b) using battery energy storage (BES) to capture excess wind generation, and (c) a hybrid method combining this two approaches. The economic viability of the hybrid method is investigated via a developed linear programming model with the objective of profit maximization, which in extreme cases will converge to one of the other methods. Numerical simulations exhibit the merits of the proposed model.","PeriodicalId":249041,"journal":{"name":"2016 North American Power Symposium (NAPS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125727006","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}
