With these DER assets located near the substation, integration to existing SCADA could certainly allow the DER to be manually dispatched by a system operator. The issues with this integration is that it fails to provide fast automated continuous dispatch responses that can not be provided with existing SCADA systems that are tied to a central Energy Management System (EMS). Central generation dispatch over 20 seconds or so are done automatically and continuously, but that’s not fast or reliable when dealing with local protection and local equipment issues like contingency overloads. Automated intelligent dispatch at the local level provided by the CALM Power Broker considers the reliability required and the Energy Storage levels and DER abilities at the substation to maintain tie-flow reliability, while enabling monetization of non-reliability reserved energy storage and other DER through passive or active market participation.
SCADA is just not fast enough to deal with responses that revolve around relay protection and other inverter based systems. The model of leveraging the existing EMS and SCADA systems or relying on third party cloud systems is ineffective when counting on milliseconds for proper decision making and dispatch responses that effect the substation and its feeders. CALM Power Broker’s proven technology enables this level of intelligent response.
