Energy Control Center (ECC) microgrids with EcoStruxure Microgrid Operation (EMO) and EcoStruxure Microgrid Advisor (EMA) are compelling examples of the EcoStruxure Power architecture.

Connected products like SE’s Smart Breakers operate autonomously in milliseconds to provide essential protection functions.
The EMO edge controller makes decisions in seconds to provide resiliency for the building. For example, if the utility grid goes down, the edge controller senses the loss of energy and disconnects from the utility grid by commanding the Energy Control Center’s main breaker to open. The ECC then starts the genset and restores power to the loads.
The EMO edge controller also manages multiple Distributed Energy Resources (DERs). Solar power is an interesting example: When the utility is operating, solar inverters generally produce as much power as possible because sunlight is free. The ECC can even facilitate exporting excess PV power onto the utility grid if permitted by the local utility.
- When a utility outage occurs, most solar PV systems do not operate during a utility outage (many people are shocked to hear this). However, an ECC can utilize solar PV systems during a utility outage.
- The EMO edge control enables PV to operate during an outage by using an alternate “anchor resource” (e.g. a genset or Li-ion storage system). The solar PV inverters connected to an ECC will see the stable voltage and frequency from the anchor resource and will resume normal power production.
- During a utility outage, if there is too much solar PV power, the EMO edge controller will automatically reduce PV power output in order to prevent backfeeding a genset or a storage battery that is full. Conversely, if there is not enough power available from the DERs, the EMO edge controller will shed load(s) intelligently.
The EcoStruxure Microgrid Advisor maximizes the ROI of the DERs. For example, for a site with a Battery Energy Storage System (BESS), the EMA system can autonomously instruct the Energy Control Center to charge, discharge or idle the battery depending on the optimal use of energy throughout the day. Utility tariffs, peak demand charges and load spikes can all factor into the decisions that EMA will make regarding the best use of the BESS.
