BS EN 61970 is a series on Energy management system application program interface (EMS-API). The energy management system application program interface is a system of computer-aided tools used by operators of electric utility grids to monitor, control, and optimize the performance of the generation or transmission system. BS EN 61970-1 provides a set of guidelines and general infrastructure capabilities required for the application of the EMS-API interface standards. BS EN 61970-1 describes typical integration scenarios where these standards are to be applied and the types of applications to be integrated. A reference model is defined to provide a framework for the application of the other parts of these EMS-API standards. This reference model is based on a component architecture that places the focus of the standards on component interfaces for information exchange between applications in a control centre environment. While the primary objective of the EMS-API is to support the integration of applications within the control centre, the reference model is also applicable to information exchanges between control centre applications and systems external to the control centre environment, such as other control centres, ISOs, RTOs, and distribution systems. BS EN 61970-1 describes the role of the other parts of the standard, including the Common Information Model (CIM) in the IEC 61970-3XX series, the Component Interface Specifications (CIS) in the IEC 61970-4XX series, and Technology Mappings in the IEC 61970-5XX series. BS EN 61970-1 also includes general capabilities that are needed by the integration infrastructure to facilitate the exchange of information via the component interfaces specified by the CIS.
Note: BS EN 61970-1 does not specify individual implementations or products, nor does it constrain the representation of information within a computer system application.
BS EN 61970-1 on Energy management system application program interface is useful for:
The energy management system application program interface can be used in small scale systems like microgrids. BS EN 61970-1 defines application program interfaces (APIs) for an energy management system (EMS). This standard is based to a large extent upon the work of the EPRI Control Center API (CCAPI) research project (RP-3654-1). The principal objectives of the EPRI CCAPI project are to reduce the cost and time needed to add new applications to an EMS or other system1, protect the investment in existing applications that are working effectively, improve the capability to exchange information between disparate systems both within and external to the control centre environment. The technical approach is to provide an integration framework for interconnecting existing applications/systems that are based on a common architecture and information model and independent of the underlying technology. The principal task of BS EN 61970-1 is to develop a set of guidelines and standards to facilitate, the integration of applications developed by different suppliers in the control centre environment2 and, the exchange of information to systems external to the control centre environment. The scope of BS EN 61970-1 includes other transmission systems as well as distribution and generation systems external to the control centre that need to exchange real-time operational data with the control centre. Therefore, another related goal of BS EN 61970-1 is to enable the integration of existing legacy systems as well as new systems built to conform to these standards in these application domains. Using BS EN 61970-1 you can provide a set of guidelines and general infrastructure capabilities required for the application of the EMS-API interface standards.
