Ameren is the first investor owned utility to use a microgrid to island customers on an active feeder. This is one of the few microgrids in the world that operates at utility-scale voltages and has multiple levels of control. This presentation by will discuss their decision making process and strategy for deploying a highly complex system.
This provides multiple sources of distributed generation, solar and wind power, energy storage, and advanced automation to support customer load. In the event of a power outage, the microgrid islands from Ameren’s grid and use the available generation resources and energy storage to reform the grid and provide stable, long-term power to residents and businesses. During normal operation, the microgrid uses various generation resources to optimize the efficiency of the power system and allow Ameren to demonstrate how microgrids can help their 2.4 million customers incorporate more distributed energy resources.
