The Gulf Coast in general and the state of Louisiana in particular include a relatively high number of industrial plants that are connected to the electric grid, and continuity of electricity to these industrial plants is of vital importance in flow of energy from Gulf Coast states to the rest of the nation. The purpose of this paper is to identify the tropical storms and their characteristics in the last fifty years, to determine the existing industrial plants, including their products and services, and to develop an algorithm that results in the impact of tropical storms and hurricanes on continuity of electricity to any specific industrial plant in the Gulf Coast geographical area. The study determines “islanding” of part of the grid that may result from the impact of the simulated tropical storms and would provide sufficient information to plant managers for continuing or halting their plant operation in time prior to the landing of tropical storms or hurricanes. This paper includes a summary of simulation results of 50 historical and 26 hypothetical tropical storms on selected industrial plants in the geographical area. To display the usefulness and practicality of the developed algorithm, we will include results of one case study in the state of Louisiana. Further work on use of the developed algorithm in hardening and development of resilient transmission system in Gulf Coast states will be reported in future publications.","PeriodicalId":409438,"journal":{"name":"2015 Clemson University Power Systems Conference (PSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128721744","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 purpose of this investigation is to create an automatic process that determines the possible fault currents at all locations of transmission lines to help guide field personnel through selection of grounding wires that are appropriate for the level of the fault currents at corresponding locations. When the power system topology changes, the fault currents at different locations of the lines change. The automation updates the information and contributes to safer environment for field personnel. ASPEN OneLiner, a short-circuit analysis program, was used to perform sliding fault analysis - a series of short circuits placed at incremental distances between the two endpoints of a transmission line resulting in a current profile that shows the fault current level as a function of distance along the line. The paper includes a case study that demonstrates practicality of the method for simulation and analysis of power systems.","PeriodicalId":409438,"journal":{"name":"2015 Clemson University Power Systems Conference (PSC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124422931","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 large number of buses and interconnections across multiple areas result in a complex network and cause an increase in computational requirements on the processor. In order to meet the requirements of this increased complexity for state estimation, distributed estimation is getting attention nowadays. A new approach based on Cellular Computational Network (CCN) for static state estimation is proposed to overcome the computational demand of large power networks in general. The CCN architecture requires a cell at every bus where the states need to be estimated. A cell uses locally available information to estimate voltage magnitude and angle of its bus. The cells exploit output information of other cells in some electrical proximity prior to computing the outputs for next time step. Beside the promise of scalability of the CCN architecture, a fully observable system for state estimation and other applications can be realized. As the traditional estimators take all the measurements at a time and executes the estimation, missing some of the measurements may cause it to loose observability. In this paper, CCN based architecture is implemented with the popular Weighted Least Square (WLS) estimator on nonlinear power flow equations to estimate off-line data. Through simulation, the scalability and observability of the CCN based framework is investigated.","PeriodicalId":409438,"journal":{"name":"2015 Clemson University Power Systems Conference (PSC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127906063","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}

Since these sources are of variable and uncertain power output, power system operators would come across many challenges in operating future electric power systems. Increasing penetration of variable RES specifically wind power generation could lead to an increased need in operational flexibility within power systems, so that a more flexible power system could accommodate a larger amount of variable RES and effectively deal with increased variability and uncertainty of the system net load that results from the inherent intermittency of RES. Among options available, energy storage systems (ESS) could be considered to address this issue. In this paper, compressed air energy storage (CAES) is introduced and investigated for this purpose. A stochastic programming market-clearing model is presented to examine CAES capability for enhancing operational flexibility in power systems with high penetration of wind power. In order to demonstrate the efficacy of CAES, some case studies are carried out in a three-bus test system. The satisfactory results verify CAES ability at enhancing power system operational flexibility in terms of reduction in wind power curtailment and system operation cost.","PeriodicalId":409438,"journal":{"name":"2015 Clemson University Power Systems Conference (PSC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130692338","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}
