    2. Microgrid Maintains Power Supply During Emergency Simulation

      Microgrid Maintains Power Supply During Emergency Simulation

      The Bronzeville Community Microgrid can keep power flowing in an emergency, ComEd recently announced after conducting a test. The “simulated islanding” test checked the resiliency of the microgrid by mimicking events that have the potential to affect power delivery, including weather calamities,  cyber attacks and acts of terrorism. The tests ComEd conducted demonstrated the microgrid’s ability to provide power in island mode while drawing upon distributed energy resources (DER), including battery energy storage and solar photovoltaic PV, to serve customers.

      Flexible Energy Storage Solutions

      Thousands of megawatt-hours of electrical energy squirreled away into utility-scale energy storage plants to cover the spread between generated renewable energy and the lowest reliable operating limit during the 10 a.m. to 3 p.m. “duck curve” period of the day — does this sound like a glimpse into the far future of major utilities across the United States and the world? But the future has already arrived at the Carolina operating companies of Duke Energy. The Duke Energy Progress Company, serving customers primarily in the eastern half of North and South Carolina, managed a whopping 106 GWh of excess energy in 2017, largely generated from utility-scale solar in North Carolina, using pumped hydro energy storage.

      Kilowatt, Kilowatt-Hours Unite

      The Energy Storage Association (ESA) was holding its annual event this year in Charlotte, North Carolina, U.S., and I was feeling the need to catch up with innovations in battery storage. I discovered the ESA is a great gathering place for technologists, startups, mature vendors, utilities and university types — a mosh pit of those who drive the energy storage future. Black & Veatch hosted an awesome evening reception at the NASCAR Hall of Fame, and I had the good fortune of running into my friend Bill Muston. Bill is the technologist at Oncor who toured me about the Oncor microgrid located at their general services headquarters facility a bit outside of Dallas, Texas, U.S. Check out the article in the April 2016 issue of T&D World that provides details of this microgrid, including the installation of photovoltaic panels, Tesla storage batteries and a Capstone turbine.
