CERTS Microgrid Test Bed Battery Energy Storage System Report: Phase 1

This document is a report on testing conducted with a Battery Energy Storage System (ESS) connected to the CERTS Microgrid Test Bed, located at American Electric Power’s Walnut Test Site in Groveport, OH. The testing is designed to demonstrate the ESS’s conformity to the CERTS control methodology and to properly interact with the existing CERTS compatible distributed energy resources.

A CERTS microgrid utilizes a set of control algorithms common to distributed energy resources which allows for system wide stability within rated conditions without a requirement for direct communications between devices.  This type of network, peer-to-peer and plug and play, creates no dependencies as in master-slave control architectures allowing for high system flexibility and reliability.
