What is BS EN IEC 61970‑457 about?
BS EN IEC 61970 is a series on energy management system application program interface (EMS-API). Energy Management system application program interface is a computer-aided tool used by power system operators to monitor, control, and carry out optimal energy management. BS EN IEC 61970‑457 specifies a standard interface for exchanging dynamic model information needed to support the analysis of the steady-state stability (small-signal stability) and/or transient stability of a power system or parts of it. The schema(s) for expressing the dynamic model information is derived directly from the CIM.
BS EN IEC 61970‑457 defines the descriptions of the standard dynamic models, their function block diagrams, and how they are interconnected and associated with the static network model. This type of model information is assumed to be pre-stored by all software applications hence it is not necessary to be exchanged in real-time or as part of a dynamics model exchange.
BS EN IEC 61970‑457 supports the exchange of the following types of dynamic models:
- Standard models
- Proprietary user-defined models
Note: The scope of BS EN IEC 61970‑457 includes only the dynamic model information that needs to be exchanged as part of a dynamic study, namely the type, description and parameters of each control equipment associated with a piece of power system equipment included in the steady-state solution of a complete power system network model.
Who is BS EN IEC 61970‑457 for?
BS EN IEC 61970‑457on energy management system application program interface is useful for:
- Human Resources Information Systems sectors
- Facilities Management companies
- Resource Management sectors
- Building Automated Control Systems sectors
Why should you use BS EN IEC 61970‑457?
The purpose of an energy management system application program interface is to determine power generation or power demands that minimize a certain objective such as generation cost, power loss, or environmental effect. BS EN 61968-457 guides you about the format and rules for exchanging dynamic modelling information based upon the CIM (Common Information Model) to accommodate the data requirements that would be exchanged to completely specify the dynamic case.
BS EN 61968-457 enables interoperability among different software vendors used by utilities to help ensure bulk power system reliability and security of supply. BS EN IEC 61970‑457 provides you with information on standard models where models are contained in predefined libraries of classes interconnected in a standard manner that represent the dynamic behaviour of elements of the power system. The exchange only indicates the name of the model along with the attributes needed to describe its behaviour.
BS EN IEC 61970‑457 implementation also specifies information on proprietary user-defined models which is stated as an exchange that would provide users with the ability to exchange the parameters of a model representing a vendor or user proprietary device where an explicit description of the model is not described. The connections between the proprietary models and standard models are the same as described for the standard models’ exchange. The recipient of the data exchange will need to contact the sender for the behavioural details of the model.
BS EN IEC 61970‑457 can be beneficial for you as the energy management system application program interface can be used to develop your own custom solutions for taking data from the energy management system and using it elsewhere, such as another software application, a digital sign, or a web page. You can use our APIs to develop your own custom solutions for taking data from the energy management system and using it elsewhere, to display information on calendars, websites, digital signage, and to integrate with third-party service systems.
