Item Optimization- and Rule-based Energy Management Systems at the Canadian Renewable Energy Laboratory microgrid facility(Elsevier, 2021-03-05) Restrepo, Mauricio; Cañizares, Claudio A.; Simpson-Porco, John W.; Su, Peter; Taruc, JohnThis paper presents the development, implementation, and commissioning of two different Energy Management Systems (EMSs) for the Canadian Renewable Energy Laboratory (CANREL), a microgrid testbed located in Guelph, ON, Canada, for the existing hardware, software, and communication infrastructure, which constrained the implementation options. A Rule-based EMS (RBEMS), which is typically found in microgrid controllers nowadays, and an implementation of an Optimization-based EMS (OBEMS), which is not usual in today’s controllers, are proposed, tested, and demonstrated in the microgrid testbed. The RBEMS consists of a state machine that represents the commitment of different genset units in the system and the curtailment of load and renewable generation. The OBEMS is based on a unit commitment model for microgrids that minimizes the generation and curtailment costs, while operating the microgrid equipment according to technical limits. Both EMS systems are integrated into a Python application which integrates various open-source packages and solvers, making it affordable, flexible and easy to replicate and upgrade. The successful implementation and performance of the EMS is discussed, showing that the components of the microgrid follow the dispatch commands, with the OBEMS yielding better overall results than the RBEMS, as expected, using the existing communications links and maintaining the stability of the microgrid.Item The Canadian Renewable Energy Laboratory: A testbed for microgrids(Institute of Electrical and Electronics Engineers (IEEE), 2020-03-04) Nasr-Azadani, Ehsan; Su, Peter; Zheng, Wenda; Rajda, Janos; Canizares, Claudio; Kazerani, Mehrdad; Veneman, Erik; Cress, Stephen; Wittemund, Michael; Manjunath, Manoj Rao; Wrathall, Nicolas; Carter, MikeThis 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.
