These challenges must be met in the face of shrinking capital budgets and an aging cable infrastructure. The traditional methods used to assess the condition and subsequently maintain distribution cable systems seem inadequate and untenable given the realities of existing distribution systems and the constant pressure to increase shareholder value. Utilities must develop new cable repair and replacement strategies that rely on an effective condition-based approach to managing these critical assets. Fortunately, a proactive cable asset management strategy, based on defect specific technologies that produce standardized partial discharge (PD) measurements, can provide utility planners with the condition-based information necessary to minimize capital expenditures and maximize reliability. Based on the results of a pilot program that mirror the performance of other utilities in North America, the subject utility has developed a large scale program to strategically address aging solid dielectric cable assets.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"97 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86045664","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 relationship between generation costs and generation types is developed first using real-time fuel cost data. The locational marginal price (LMP) at any bus in the system is then used to determine the generating unit type that is “marginal” at any specific point in space and time. Emission factors associated with power generator types are obtained through data from the US Environmental Protection Agency (EPA). Historical energy consumption and emissions data is used to validate the approach. The model can be used to estimate changes in emissions associated with incremental changes in power demand or shifting of power demands in space and time. A pilot study has been carried out using demand loads from the water distribution network of the Detroit Water and Sewerage Department (DWSD). The DWSD is one of the largest water utilities in the US; the electric power dispatch is managed by the Midwest Independent System Operator (MISO). The paper provides examples of potential applications of the model to improve public awareness of sustainability issues associated with personal energy consumption decisions.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"88 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":"82123390","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 is achieved by modeling residential demand response considering Plug-in Hybrid Electric Vehicles (PHEVs) as part of the loads, local renewable generation capability and variable energy pricing based on a Time of Use (TOU) scheme. A mathematical model of the system is built based on realistic data, and the evaluation of the survivability of the system is carried out using Monte Carlo simulations and statistical experiment design techniques, where the probability of overloading the distribution system is derived for different scenarios. Results obtained show that the coordination mechanism is able to achieve energy efficiency and cost saving for residential users when the energy consumption is managed properly. At the same time the probability of overloading the distribution system can be reduced. The efficiency and economic savings depend on the potential of renewable sources in the region considered and the survivability of the system depends on a reliable communication infrastructure.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"24 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":"75969863","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 B.C. Province Government expects such growth will continue. The British Columbia Utilities Commission (BCUC) and provincial power utility BC Hydro are forecasting 20% to 40% growth on electricity demand in the next 20 years, and are setting a goal to be electricity self-efficiency by 2016. Meanwhile, much of BC Hydro's transmission and distribution system was built between 1940 and 1980. The aging infrastructure coupled with the growing demand present various challenges to BC Hydro. BC Hydro embarked on various transmission and distribution network and substation upgrade projects. Upgrading existing lines and substations is a vital part of the infrastructure upgrade program. The refurbishment of existing substations with legacy devices and systems in service, is one of the most challenging tasks. In order to maximize the utilization of old and new systems, to facilitate decision making and planning, and to improve operation and maintenance efficiency, substation HMI upgrade becomes an important part in the upgrade project. This paper describes the project objectives and goals, as well as value and benefits. It discusses the challenges in designing new substation system standards to incorporate new technologies from multiple suppliers while working with the constraints presented by other legacy standards and devices. In addition, the technical requirements, selection criteria, future migration consideration are discussed. It further highlights new standards roll out, implementation and change management challenges. This paper will conclude with the results of the upgrade project, as well as lessons learnt.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"40 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88044040","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}
