Distributed Resource Interconnection Studies

RLC has performed numerous Distributed Resource (DR) Interconnection Studies for utilities throughout New England. Distributed Generation (DG) Interconnection Studies are performed to determine modifications to the distribution feeder and project to comply with State Tariff requirements, IEEE 1547, and Utility Standards. These potential modifications are determined by several different analyses:

  • Short Circuit analysis
  • Effective Grounding analysis
  • Steady State analysis to include voltage profile, thermal capacity analysis, and reverse powerflow
  • Voltage Flicker assessment
  • Anti-islanding determination of Direct Transfer Trip (DTT)
  • Design Review
  • Special Studies (Long term dynamic, transient analysis)

Distributed Resource Interconnection Studies Performed:

  • Over 80 solar photovoltaic project interconnection impact studies
  • CHP and anaerobic digester synchronous generator impact studies
  • Juniper Ridge landfill gas powered synchronous generation
  • 98 MW Solar photovoltaic project
  • Voltage Needs Assessment of a distribution system with impacts of DR
