Advanced smart grid distribution testing

This paper will present the design of SCE's Smart Grid Test Facility (SGTF) and equipment test. This facility can be used to test, demonstrate, and validate utility distribution equipment performance before, during, and/or after their installation in the grid. This test facility's voltage, frequency, real power, and reactive power will be completely controlled where the equipment's automation, protection, and communications performance can be fully evaluated. This paper will provide the following additional information. First, it will provide a layout of the two distribution circuits in this facility with the equipment that will be installed to support the testing. Additionally, this paper will provide an overview of various tests that will be performed at SGTF to assess equipment performance. Furthermore, it will provide the ability to test automation and protection schemes that are otherwise prohibited to perform in the field. Finally, it will provide recommendations on additional uses of this facility such as training, installation procedures, volt/VAR control schemes, and communications. This facility will provide us the ability to pre-test pilot or new equipment without adversely affecting or disturbing customers.
