Microgrid Expansion Required with Zero Disruption in Service
A major utility company needed to increase the capacity of a microgrid supporting more than 3,000 residential customers located at the end of a transmission line in an area that commonly has severe weather conditions. They needed to add two 1.8MW diesel generators and battery storage without disrupting service to their customers. The utility-owned microgrid is also connected to distributed energy sources owned by customers making it even more important that there be no disruption. This project required an experienced team and best-of-breed equipment to facilitate the appropriate test, with an accurate load.
Resistive/Reactive Load Bank Package
With the customer’s mandate for no service disruption, the team engaged ComRent’s load bank specialists to carefully plan the project. Based on ComRent’s recommendation, the final decision was made to design the solution using a resistive/reactive load bank that could mimic motor loads, electromagnetic devices, and complex protective relay functions within a power system.
ComRent’s technicians coordinated the site logistics, setup specialty cables, installed a 200 KVA generator to power the load bank controls and executed the test in a safe, clean environment.
Successful Commissioning Enabled Microgrid Expansion with No Service Disruption
ComRent delivered a load bank solution that isolated and successfully commissioned the microgrid. By using a resistive/reactive load bank, ComRent easily confirmed the paralleling switchgear performance and device settings, providing a meaningful and timely test for the utility customer. Importantly, all load bank testing was completed without any disruption to the distributed energy sources.
