Objective: To advance measurement science for the performance of smart meters and associated metering standards and test procedures that will enable accurate and fair electricity metering needed for the smart grid, by 2016.
What is the new technical idea? This project will develop test procedures and protocols that apply real-world waveforms that are dynamically changing and have varying amounts of distortion present along with bi-directional power flows to smart meters. The project will also conduct tests to ensure that meter accuracy is not affected by interference from the communication module in the meter.
What is the research plan? To develop a smart meter testing facility to develop performance test requirements to ensure smart meters are accurate under field conditions.
NIST will develop a smart meter test bed to test meters under real-world conditions and verify meter accuracy, first to 0.2% and then upgrading to an accuracy of 0.05% to support the best commercially available meters anticipated in the near future. In parallel with this testing, an ANSI standard for high accuracy metering will be developed with technical input from NIST. The smart meter testbed will then be utilized to conduct distorted and bi-directional flow testing on smart meters.
