Distributed Energy Resource Interconnection Studies

While distributed energy resources (DERs) can offer societal and utility benefits — by creating an alternative to large generating plants for energy supply, and by providing other grid services such as load shedding and frequency response — their interconnection challenges the traditional planning, construction and operational assumptions that dictate the current distribution system design. Therefore, it is important to carefully and thoughtfully study these interconnections to promote continued safe and reliable operation of the distribution system, and also to properly allocate the cost of any impacts. We have extensive experience modeling and studying DER interconnections and helping our utility clients manage extensive queues of interconnection requests.



HOW WE HELP

Our diverse team, spread across the nation, can be deployed as individual subject matter consultants or as scalable project teams to complete these studies in the required timelines. We help with the modeling and assessment of third-party or utility-owned DER interconnections, with analysis including:

  • Load flow
  • Short circuit
  • Probabilistic flicker
  • Protection coordination
  • Harmonics
  • Time series
  • Control interaction
  • Ground fault overvoltage
  • Load rejection overvoltage
  • Effective grounding
  • Risk of islanding

OUR APPROACH

At 1898 & Co., we believe in planning and analysis grounded in feasibility and engineering knowledge. We strive to simplify the transition from planning to construction by delivering planning results that are constructable and easy to understand. This starts with thoughtful integration with and understanding of your unique criteria, standards and constraints. We license and train our consultants in the use of industry analysis tools such as Cyme, Synergi, WindMil and CymTCC, as well as common data visualization and collection tools such as ArcGIS, Smallworld, Pi Historian and more. This approach allows our consultants to:

  • Quickly integrate with client teams.
  • Limit the client’s oversight burden.
  • Increase responsiveness and reduce project delivery times.
