The Canadian Renewable Energy Laboratory: A testbed for microgrids

This article presents a test facility for design validation of microgrids with high penetration of renewable energy, developed as a joint effort with industry, government, and academia. The Canadian Renewable Energy Laboratory (CANREL) described here is a physical simulation tool for the design, development, and performance testing of islanded and grid-connected microgrid projects. CANREL is equipped with a diesel generator, different renewable energy sources, various renewable energy generation simulators and physical systems, a bidirectional power-flow grid simulator, a battery- based energy-storage system, and controllable resistive?inductive?capacitive and electronic test loads for the design and testing of a variety of microgrid solutions. The test facility provides project performance demonstration and validation services at each stage of a microgrid project development to help utilities and project developers reduce risks. It is also a physical simulation tool for benchmarking microgrid equipment and controllers for research and development purposes. Some facility test results are presented in this article to demonstrate the capabilities of CANREL for simulating a wide range of scenarios.
