The competencies of the forensic electrical engineer include the knowledge of engineering standards and best practices, familiarity with applicable laws and regulations, as well as wise decision making. In this paper, functions and duties of the forensic electrical engineer preparing for a trial are discussed and quantitative methods of technical evaluation are proposed. Around the world, institutions establish and define the competencies of the forensic engineer, and promote the advancement of the forensic science through conferences, and publications. To resolve the historical dichotomy between the logic of the \"certainty\" required by the judicial outcome of proceedings, and the logic of the \"uncertainty\" of the engineering, this paper suggests utilizing the subdivision of accident-related trials, when a risk assessment must be provided, into two levels; a junior \"engineering\" level (which may be public is some jurisdictions, confidential in others), followed by a senior level or formal trial, might together better support the formulation of the verdict by providing a more exhaustive analysis of the accident causation, and parties' responsibilities. Key words: forensic science, logic of certainty and uncertainty, fuzzy logic, technical investigation, cindynic model.","PeriodicalId":266558,"journal":{"name":"2016 IEEE/IAS 52nd Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"747 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116098840","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 increasing container number moved makes necessary the compensation of high values of energy absorbed from the utility by promoting renewable energy sources and an innovative approach of a coordinated management of the global energy absorption of all the port tenants (microgrid management). The paper deals with the relevance of system integrity aspects in the design phase and in its following management. Electrical distribution architecture, integrated at least by two independent sources from the utility company, has a vital impact on system availability throughout its lifecycle. Thanks to a flexible power distribution system assisted by a prompt reaction of a qualified maintenance staff, system critical loads could be re-energized in emergency condition such as faults, maintenance operations and interruption of one energy supply from the utility company. The paper used as reference the Port of Long Beach for the data reported as example.","PeriodicalId":266558,"journal":{"name":"2016 IEEE/IAS 52nd Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"1228 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122548522","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}

Battery energy storage systems (BESS) connected to the grid via power electronics are well suited to be deployed in large numbers in Smart Grid applications to provide system services like load balancing, grid stabilizing and power quality management. Control and optimization of BESS operation rely on the availability of accurate and adaptive models. In particular, dispatch optimization in energy management systems demands regularly updated, simple and reliable battery models. As time-consuming parameterization testing imposes additional costs and operating constraints on BESS, adaptive battery parameter and state coestimation provides an inexpensive on-line solution. A novel observer technique based on gradient descent optimization, that provides estimates of unknown and variable battery parameters and of the internal battery state, is proposed in this work. The coestimation is validated using experimental data from commercial Li-Ion batteries and the test results are reported.","PeriodicalId":266558,"journal":{"name":"2016 IEEE/IAS 52nd Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126893422","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}

After a cable is isolated from the system, its trapped charge starts to slowly discharge. We may need to determine the discharge time for multiple reasons such as safety, and limitations on circuit breaker capabilities to withstand capacitive inrush currents. This paper will modify the existing method of discharge time calculation considering the fact that the ends of the cable remain connected to the switchgear bus after cable isolation. A procedure is also presented to calculate the discharge time for the combination (series connection) of underground cables and overhead lines. Sensitivity studies are performed to investigate the effects of different factors such as the type and conditions of the line insulator and design voltage level on the discharge characteristics. All the studies are conducted on a real transmission system. However, the procedure and findings are general and can be used in any application such as in a distribution system or any industrial power system.","PeriodicalId":266558,"journal":{"name":"2016 IEEE/IAS 52nd Industrial and Commercial Power Systems Technical Conference (I&CPS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128502614","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}
