PUI: Interconnecting DG & Energy Storage to the Power System

Starts:  Sep 10, 2019 8:00 AM (ET)
Ends:  Sep 12, 2019 12:00 PM (ET)

Who Should Attend:

This two and a half day course is designed for engineers, distributed generation system integrators and energy planners who need to learn about or enhance their background in distributed generation technologies and interconnection issues. An electrical engineering background and basic knowledge in three phase power and power distribution systems is recommended. The course will also be of interest to non engineering utility professionals who deal with regulators and customers on DG issues and seek a more extensive understanding of the various technical aspects involved with interconnection.

Topics Covered:

Topics covered include:

  • Class Introduction and DG Overview
  • Review of DG Technologies
    • Internal combustion engines
    • Small combustion turbines
    • Fuel Cells
    • Photovoltaic (PV) systems
    • Wind turbines
    • Small scale hydro
    • Small steam turbines
    • Cogeneration technologies
    • Energy storage devices
  • DG Power Converters and Operating Behavior
    • Inverters
    • Synchronous generators
    • Induction generators
    • Loading
    • Dynamic response
  • DG Power System Impacts
    • Voltage regulation
    • Flicker
    • Impact on fault levels
    • Relay and fuse coordination issues
    • Ground fault overvoltage
    • Islanding issues and protection
    • Harmonics, power quality, ferroresonance
  • Interconnection Practices, Requirements and Standards
    • Relays and settings
    • IEEE, UL and other standards
    • Typical interconnection configurations
  • Strategies and Emerging Technologies to Handle Higher Penetrations of DG


Each topic is taught from the perspective of both the theory and practical application based on proven industry experience. Informal quizzes and problem solving are utilized to enhance the instructional experience. A sample problem or set of problems will be worked through for most sections of the class. Students should be proficient with a scientific calculator and bring one to the class so that they can work through the exercises.

Problem exercises include:

  • Calculating fault contributions from generators
  • Calculating the voltage influence of a generator on the power system
  • Screening for voltage flicker due to DG energy sources
  • Calculating life-cycle cost of energy from various DG sources
  • Determining if protective relaying setting adjustments are needed
