A model-driven approach to Smart Substation automation and integration for Comision Federal de Electricidad

Abstract

Historically, utility substation engineering and protection departments have tended to work independently from grid operations. For example, EMS (Energy Management System) or SCADA systems typically do not fully model substation protection schemes and conversely, substation protection schemes typically have limited knowledge of the power system network topology models of the grid. At CFE -Comision Federal de Electricidad, Mexico, this is exactly the challenge being faced. However the need for a "Smart Grid" or particularly a "Smart Substation" creates new requirements for real-time measurement data and utility model sharing between these two separate worlds. While protection and grid operations traditionally try to work closely to share more detailed information, it is likely that these departments still will not merge easily. Thus, there is a need for the introduction of a unified platform established in CFE that has visibility on merged network models and device models such that new overarching enterprise-wide applications can be developed for the utility. This paper discusses standards for network and device modeling can be leveraged to create an open and flexible development environment.

Model Driven Software Engineering of Power Systems Applications: Literature Review and Trends

“…Subject of studies found using ''strategy 4'' involve automatic generation of simulation models from a standardized power system model [52], deriving test bed configurations for automation systems validation [53] and model transformations for survivability analysis [54]. Study [51] is a survey of promising standards for network and device modeling to be used in a development environment.…”

“…• The use of IEC 61850 SCL in the context of MDE is observed in seven of the reviewed studies (references [33]- [36], [43], [47], [51]). SCL however is focused in the automation level, and its applicability to EMS applications development is questionable.…”

“…In total, 25 out of the 40 reviewed studies mention such concepts. Out of these 25 studies, 20 are closely related to power systems automation or smart grids applications, and just five mention concepts related to energy management (references [4], [17], [46], [51], [52]).…”

Using IEC 61850 GOOSE messages in microgrid protection

“…Furthermore, transmission line power losses are reduced, and energy efficiency is improved because local loads are supplied by DERs. Although the DER systems are gaining popularity, they derive the difficulties of control and protection in power grids …”

“…Although the DER systems are gaining popularity, they derive the difficulties of control and protection in power grids. [5][6][7][8] Centralized generation is the common practice in conventional power systems where protection coordination is relatively simple because the power flow and fault currents in the power lines are unidirectional. However, the situation is quite different from the microgrid operations.…”
