Power Systems Engineering
The grid and its controls. Engineered together.
Distributed energy resources, battery storage, EV charging, data centers, and grid-edge controls are making the distribution grid more active and operationally complex: changing power flow, fault response, and system visibility. Integrating them takes more than a stand-alone study: the electrical system and its digital control infrastructure must be engineered together, from planning through operations.
Offerings
OES engineers the electrical system and its control infrastructure as one: system studies, protection settings, automation logic, and communications — from problem definition through lab validation, commissioning, and operational support.
Solar, battery storage, and grid-forming or grid-following inverters — grounding, voltage regulation, protection impacts, and controller interactions across every operating mode.
Power flow, short-circuit, and feeder studies that quantify voltage performance, equipment loading, and fault duty for new resources, data centers, and EV fleet charging.
Relay-settings and coordination review, RTAC and automation logic, and end-to-end functional testing of the complete scheme rather than isolated devices.
IEC 61850, DNP3, Modbus, and OpenFMB integration with point mapping, timing, data-quality, and failure-response verification across field devices, gateways, and operational applications.
Operating-mode design and verification for grid-connected, islanded, transition, and return-to-grid operation, with protection and controls validated against the full switching sequence.
Factory and site acceptance testing, energization readiness, and root-cause resolution across settings, logic, wiring, networks, protocols, and data quality.
OES keeps power systems at the center. Controls, communications, and software are judged against actual electrical behavior rather than treated as separate layers. New concepts are written as testable requirements and proven on hardware before they reach the field. And the same engineers carry the work from analysis and simulation through commissioning, troubleshooting, and operations.
