50157: Application of Energy Storage Technologies in Power Distribution Systems

This report reviews energy storage (ES) technologies and assesses them based on several technical metrics. Potential applications of the technologies in distribution system are identified, categorized, and discussed. Real-world examples of utility-scale ES deployment use cases and experiences are presented. In addition, two case studies on key energy storage applications in distribution systems are conducted and technical parameters are determined. This report will help utility engineers gain a

0149: Optimization of Coal-Fired Power Plant Modifications to Improve Cyclic Performance

This study examines improvements to coal-fired power plants to adapt base-loaded units to cyclingoperation. The primary goal of the study is to prioritize the required improvements to a cycling powerplant (based on studies that have been conducted and provided) such that operators can select themodifications to be implemented from a cost-benefit perspective. The benefit of improvementprojects is quantified in terms of avoided forced outage hours (FOH). Literature sources wereconsulted to develop

3071: Development of a Predictive Analysis Program for Evaluating the Success of Reclamation of Mineral Based Transformer Oils

Reclamation of transformer oil is not only a costly undertaking, but in most cases requires an outage to some part of the power system. The purpose of the reclamation process is to extend the life of the entire insulation system critical to the operation of a power transformer. The benefits of the reclamation process do not only relate to the oil quality, but also to the effect poor oil quality can have on the delicate paper component of the insulation system of the transformer. It is critical t

5166: Determination of Distribution Network Characteristics Using PQ Waveform Data

Distribution network fault levels or equivalent circuit impedances are important data for both utility companies and their customers. The data has many uses, such as specifying equipment ratings, establishing protective relaying settings, and determining the power quality impact of motor starting, among others. In this project, a novel and practical method has been developed for non-intrusive measurement of network impedances using the waveform data collected by power quality monitors. The metho

5117: Impact of Harmonics on Utility Equipment: A Survey and Review of Published Work

This report documents the results of a survey of the impacts of harmonics on utility equipment. Eight major pieces of utility equipment -- overhead line, underground cable, transformer, capacitor, reactor, induction motor, synchronous generator and switchgear -- are included in this survey.The effects of harmonics on performance, life expectancy and other operating characteristics for each type of equipment, are reviewed and documented. The mechanisms through which the harmonics produce these ef

30106A: Criteria for Spare Equipment and Parts - Phase I

In an increasingly competitive market space that has new and expanding regulatory paradigms, the need for utilities to effectively manage equipment and spare parts inventories has never been greater. To better understand the current practices within the industry, a survey of multiple utilities was conducted in order to examine failure rates, spare parts / equipment levels, and participation in inventory sharing programs. The survey focused on a representative subset of major equipment items in c
