The IEEE definition for interoperability is “the ability of two or more systems or components to exchange information and to use the information that has been exchanged” [78]. The SG is an interoperable system that should be capable of exchanging meaningful, actionable information, addressing safe, secure, efficient, and reliable operations of power systems. The systems will distribute a pre‐defined purpose of the exchanged information, and this information can expect suitable types of responses. The reliability, fidelity, and security of information exchanges among SG subsystems and components should achieve required performance levels [79]. The GWAC (Grid Wise Architecture Council) [80] has looked at, interoperability between components of the same system, or between different systems and suggests several implications to be derived;

1 The infrastructure should permit exchange of data and its transfer from senders to receivers; thus, network connectivity should be assured.

2 The implementations of the participating solutions should be able to make sense of the data given. Therefore, common symbols, protocols, and implementation‐specific interpretations thereof are required.

In the context of the SG, interoperability includes seamless, end‐to‐end connectivity of hardware and software from end‐use devices to the power source, improving the coordination of energy flows with real‐time information and analysis. Interoperability is an essential part of the success of SGs. According to the National Institute of Standards and Technology (NIST) [81] “Once appropriate levels of interoperability are achieved, policymakers, investors, engineers, and other stakeholders can turn their attention to solving a broad set of challenges: improving the efficiency of power delivery, transitioning to cleaner energy sources, and enabling new markets that surround electricity delivery.” The NIST‐coordinated interoperability effort is organized to include a wide set of stakeholders among the industry, and it is examining the purpose of standards across a wide range of SG interoperability areas [79].
