3809: Controlling the Operation of Mass Penetration Small-Scale DER

With continuously increasing customer adoption of small-scale distributed energy resources (DERs), utilities are in the process of planning for or, in some cases, currently dealing with the impacts of the high penetration of small-scale DERs (for this study, these are defined as systems with an output of 500 kW or less). Such resources are becoming critical for utilities, both for their business in general and for reliable and economic grid operations. Utilities are uniformly pursuing solutions

3329: Dynamic Finite Element Analysis of a Test Transmission Line Using ANCO Load Reduction Device (LRD)

This study presents the validation of a numerical model used to simulate the full-scale broken conductor tests performed by Electric Power Research Institute (EPRI). The transient response of the conductor and its effect on adjacent towers is presented with and without the ANCO load reduction device. The ANCO device was developed to limit the load on a transmission tower due to a broken wire. It consists of a flat plate cut to make two spirals which extend when a specified load is exceeded. Th

0530A: Benchmark Study on Torrefaction

Driven by renewable portfolio obligations, utilities are considering strategies to increase the percentage of biomass co-firing in their coal-fired units. This will require significant technical and financial investment in refurbishing the coal-fired units.Torrefaction is a thermal pretreatment technology, which produces a solid biofuel product with superior handling, milling and co-firing capabilities when compared to other biofuels. Torrefaction could produce significant cost reductions for th

50110: Data Acquisition and Monitoring of Distribution Lines with High Resolution Satellite Images

A pilot project of the potential applications of WorldView-2 (WV-2) satellite imagery was carried out in a test area inside the Montreal Metropolitan Community (St-Bruno de Montarville) for the benefit of the electric utility industry to validate the potential of using the technology in its distribution line asset management operations. The project focused on six specific activities: visual asset inspection, vegetation management, damage assessment, GIS data capture and record validation, buildi

3128: Short Circuit Contribution of Renewable Generation

This project addresses utility concerns related to the fault contribution from renewable generators, most prominently wind and solar generators. Accurate information of these fault contributions is needed for selecting equipment ratings and ensuring that the protective device coordination in power systems functions properly. The fault contribution from renewable generators, in particular inverter-based renewable generators, is fundamentally different from the fault contribution from conventional
