Massive, infrequent reliability events, such as a one in one hundred year ice storm, dubbed Catastrophic Days, can skew the threshold computation and thus affect the identification of Major Event Days and the calculation of normal reliability levels until the Catastrophic Day rolls out of the five year window. The Catastrophic Day Task Force of the Distribution Reliability Working Group has explored methods to identify Catastrophic Days and exclude them from the Major Event Day computations. One such method, Robust Estimation, is described in this work. While theoretically valid, Robust Estimation has not worked well in practice.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"14 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90433854","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 trend represents new challenges for integrators, manufacturers, and end users. However, the field-proven benefits and lessons learned are truly valuable to managers, supervisors, and executives curious about bringing the benefits of IEC 61850 to their utilities. Utilities from around the world have deployed innovative projects based on the IEC 61850 communications standard, including Elektro in Brazil, NamPower in Namibia, NTPC Limited in India, and Comisión Federal de Electricidad (CFE) in Mexico. This paper summarizes these successful deployment projects and presents network architectures and lessons learned during these projects.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"125 15 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87531234","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 approach enables observability analysis and restoration (pseudo-measurements selection) in a straightforward and simple way, without iteration, via triangular factorization of the Jacobian matrix of the weighted least square three-phase state estimator. By analyzing the structure of the matrix resulting from this factorization, the matrix HΔ3θ, the approach enables the identification of critical measurements. Numerical examples to show the performance of the approach are presented.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"15 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85028250","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 upper level is an aggregator's problem which aims to minimize the electricity payment by managing the energy consumption of three types of controllable loads. On the other hand, the lower level is a utility's problem which is assumed to be a follower. The utility's problem is a market-clearing model which provides a spot price to the aggregator's problem. We derive the Karush-Kuhn-Tucker (KKT) optimality conditions of the lower-level utility's problem as the equilibrium constraint in the upper-level aggregator's problem. Therefore, the bi-level formulation is converted into a form of mathematical program with equilibrium constraints (MPECs) which can be solved analytically. A numerical example is conducted to demonstrate the performance of the proposed model.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"3 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85078512","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}

There is often the perception that, “as long as the bills get paid our data is good enough!” As both customers and regulators owners alike are becoming more demanding in customer service and the impacts of the Smart Grid are being clarified, it has become an imperative for utilities to better manage their data. In the Smart Grid era, Asset Management at the distribution level is no longer a lofty goal but rather a necessity. Unfortunately from the perspective of technical resources, data is never good enough. Managers are faced with the challenge of balancing adequate data quality against the cost of maintaining that quality of data. This paper discusses the realities associated with data quality and a successful asset management program.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"8 2 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83618323","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 PV array, storage battery and diesel generator capacities are the variables to be optimized considering very low loss of load probability. In the proposed optimization method, a hybrid PV/diesel system model is developed in Matlab and the long term solar energy records for the targeted sites are used. The objective of the optimization problem is to minimize the system cost and to determine the optimal sizing of PV array, storage battery and diesel generator in terms of its unit cost. The proposed PV/diesel system is validated by comparing it with a benchmark system developed in [10]. The comparison is based on the lifetime cost of the system which leads to the kWh unit price. Such work is helpful for designing reliable hybrid PV/diesel system for Kuching, Malaysia at a minimum cost.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"81 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83968539","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}
