Substation Smartizing: An IEC Based Approach for Utility Smart Analytics Development

Abstract

Recognizing that to survive in 21 th century, utilities must take advantages of smart platforms, IEC has provided a homogeneous IT landscape based on CIM/XLM standardized data format for source data. It allows utilities to vitally combine their large number of autonomous IT systems, with great potential for optimizing their core processes. But this landscape itself will not be enough, unless utility actually and smartly connects IEDs and systems at that surviving critical level. This article presents an approach that tries to make easier the utility improve core processes, based on substation "smartizing", by means of creating in smart substations, key-value operating and functional data, information and knowledge, in a continuous upstream add-value process, making them suited to each IED, System and decision maker at every utility level. "Smartizing" architecture is fully IEC compliant. The approach is being applied in a 25 MVA distribution substation in Brazil, in a 10 GW demand peak utility group.  

Visualization Techniques for Electrical Grid Smart Metering Data: A Survey

“…The integration of smart substations in smart grid architecture supporting intelligence aggregation in utility operation and management is addressed in [8]. Complying with IEC CIM standards supports substation analytics and system integration with enhanced value adding information exchange.…”

“…This model facilitates exchange of power system network data between companies and allows data exchange between applications within a company; thus, easier implementation of data analytics. Its purpose is to increase reliability and reduce expenses in smart grid infrastructures, as shown in [8].…”
