OpenADR vs IEEE2030.5

Both OpenADR and IEEE2030.5 are having advantages and use cases for controlling the DER (Distributed Energy Resources) and Demand Response based programs. Below are the just Insights on the what all are functional requirements being served by both of them.

Rule 21 and the underlying Common Smart Inverter Profile (CSIP) reference the functionalities of the IEEE 2030.5 protocol to communicate with the inverter or point of aggregation, although other protocols are permitted. The IEEE 2030.5 protocol supports a wide range of DER applications, with inverter control representing a subset of that functionality. The major California IOUs created the Common Smart Inverter Profile Working Group to define the formal CSIP guidelines targeted at supporting the Rule 21 requirements. The CSIP Guidelines lay out a set of general requirements defined by Rule 21 and a set of IEEE 2030.5 protocol-specific requirements defining how the general requirements can be achieved within the context of IEEE 2030.5. The latter, however, assumes that utilities want to deal directly with millions of customer-owned inverters, creating challenges for customer service, data analysis, communication infrastructure, and many more.

OpenADR and IEEE 2030.5 have distinctly different target use cases. OpenADR typically relies on a gateway device, building EMS, or aggregator to translate utility DR/DER requirements into specific device behaviors, while IEEE 2030.5 is designed primarily to directly control devices. OpenADR does not intend to duplicate or replace 2030.5 in the context of Rule 21.

Functional Requirements of OpenADR and IEEE2030.5

? Supported – means the protocol gets the message there, end to end

? * Not Supported – means the protocol doesn't get the message there at all

? *** Supported in Combination - means the protocol can transmit the message with some support from other protocols and/or implementation of specific programming.
