Wind and Renewable Energy Studies

The growth of solar, wind and battery renewable energy sources has been brisk
the last few years and is likely to continue its high penetration of both small-
and large-scale projects. We analyze the integration of these resources onto
both transmission and distribution systems through interconnection studies or
fatal flaw assessments. We have analyzed interconnections of small and large
resources, performed siting and interconnection studies and most recently
performed studies for emerging technologies. In addition, we perform
congestion analyses to study moving large quantities of renewable energy over
long distances.
Software Applications: RLC Engineering personnel are proficient, competent
and knowledgeable users of ASPEN, CYME, EasyPower, PSCAD/ATP, PSLF,
PSS/E, SKM Power Tools, Synergi, TARA, as well as our own developed and
specialized programs.

Experience

RLC has performed hundreds of distribution system studies for utilities
throughout the Northeast, with a wide breadth of industry software
knowledge including CYME, PSCAD, Synergi, SKM, WindMil, ASPEN
OneLiner, PSS/E, SKM, TARA, EasyPower and Arc Pro.

A large portion of these have been interconnection projects ranging
from 250 kW to 35 MW. Our engineers are experienced with Smart
Inverter Technology and leveraging DER inverter capabilities to
assist in mitigating interconnection impacts. RLC is experienced with
steady-state (thermal, voltage, reactive power), short-circuit (fault
contribution, effective grounding), protection (protective reach,
coordination), time-series (IEEE1453/1547-2018 flicker), Volt/VAR
inverter setting design, Coefficient of Grounding (COG), and Risk
of Islanding (ROI) and Temporary Overvoltage (TOV) screenings.
Where ROI and TOV screenings indicate the need for time-domain
analyses, PSCAD studies are performed to ensure system
reliability while avoiding unnecessary upgrade costs.
In addition, RLC distribution system studies engineers performed
Python characterization and modeling of Switched Source’s
Tie Controller and Phase Equalizer power electronics devices
in CYME, hosting capacity analyses for Maryland utilities, arc
hazard analyses per NFPA 70E, subtransmission analyses for
ISO-NE approval, functional testing of manufacturer PSCAD
inverter models, and PSCAD-to-PSS/E model benchmarking
according to ISO-NE Planning Procedure No. 5-6.
RLC has also provided interconnection program
management services for Western Massachusetts.
