Distribution System Studies

The future distribution systems will look different than those of the past. There will be many more distributed resources and both resources and loads will need to be controlled in real time by a coordinated controller. RLC is prepared to help utilities and developers figure out how to make this all work. RLC has performed dozens of distribution system renewable resource interconnection impact studies, including equipment design upgrades. We are proficient with ASPEN, SKM, PSCAD, Synergi, EasyPower,  Power Tools for Windows, and CYME for completing these analyses. RLC understands the issues associated with unbalanced loads and are experienced at solving voltage profile, voltage flicker, effective grounding, anti-islanding, power factor, short circuit, reverse power flow and other interconnection problems. Our strengths are complimented by a strong system protection group.

Distributed Energy Resource Ground Fault Overvoltage Impacts to Rural Sub-Transmission Systems

Reverse power flow caused by increased interconnections of Distributed Energy Resources (DER) result in Ground Fault Overvoltage concerns. This RLC Engineering white paper examines this condition.
