RESEARCH REPORT

A Practical Guide for Mitigating Harmonics in Electrical Distribution Systems

This report aims to provide power quality engineers, designers, and utility site staff with practical approaches for identification and mitigation of harmonics-related issues in modern electric utility distribution systems. Harmonic distortion in electrical distribution systems is a crucial power quality issue. This issue is further magnified by the failure to establish equipment harmonics emission limits in North America. Compounding the problem is the fact that the source of the harmonics is dispersed throughout the distribution system.

RESEARCH REPORT

Power Quality Impacts of Large-Scale Adoption of Electric Vehicles (EVs) on the Grid

This research initiative will detail the causes, sources, mitigation strategies, and best design practices to manage power quality issues caused by EV charging. It aims to enhance CEATI members' understanding of system design and technologies to improve power quality issues and overall system safety by preventing asset damage due to overloading conditions. It will also address future trends and strategies for utilities to manage these challenges effectively.

RESEARCH REPORT

Enhancing Connectivity of Distributed Generators (DGs) by Control Coordination of Smart Inverters

This report is based on an extensive literature review. It offers a clear understanding for utilities and system operators about the impacts and effectiveness of different smart inverter controls for significantly enhancing the hosting capacity of PV systems on their distribution networks. The report summarizes different utility planning studies for improving the hosting capacity of DGs. In addition, lessons learned about control coordination of smart inverters are explained. The performance and impacts of different smart inverter functions in increasing hosting capacity are described.

RESEARCH REPORT

Analytical Methods for Aggregating, Characterizing, and Assessing Data from Distribution Systems

This report investigates the use of data analytics techniques in distribution utility applications. The use of descriptive, diagnostic, and predictive analytics techniques in distribution system applications are demonstrated, and examples of their use on real distribution system data provided by several North American utilities are also presented. The report concludes with a discussion of the future trends in distribution system data analytics and possible applications enabled by smart grid technologies.

RESEARCH REPORT

Stray Voltages in Higher Load Density Environments – Causes, Effects, Measurement, and Mitigation Techniques

This report describes procedures and equipment suitable for conducting consistent and repeatable evaluations of publicly and privately accessible contact voltage situations in higher load density urban environments. Although useful measurement protocols and procedures exist for some situations, such as measurements in animal contact areas, there are inconsistencies and differences in the procedures used to conduct assessments of contact voltage across other areas of interest. To that end, this document presents recommended practices for three areas of interest. Additional discussion is provided regarding causes of contact voltages and mitigation techniques.
