Distributed Generation testing and commissioning

Distributed Generation (DG) interconnections with utility systems are becoming increasingly common. After a DG application has been processed, all needed studies completed and any required interconnection facilities constructed to accommodate the safe and reliable parallel operation of the DG facility, testing and commissioning is required. This paper will describe typical inspection, testing and commissioning procedures for a range of DG installation sizes and types. Practical experience gained from real-world installations and best practices for utilities will be shared in the form of a sample check list and procedure for smaller inverter-based systems.
