Network configurator and simulator system based on CIM standard and node-depth encoding

Abstract

The extensive automation envisaged for smart networks brings challenges related to the difficulty of integrating a great deal of data from sensing, metering, actuating, control and protection devices. Application tools developed for smart grids rely on standardized and open data formats for data exchange. Effective communication depends on a common model of infor-mation about the power grid. The Common Information Model (CIM) of IEC 61970 provides a consistent definition and data structure using object-oriented modeling. In the topological modeling of distribution networks, the network data structure given by Node-Depth Encoding (NDE) has been widely used for its computational efficiency. This paper aims to present a Network Configurator and Simulator System (NCSS) capable of generating metadata of the electric network in CIM standard and con-verting them into NDE metamodels integrated to power flow and short-circuit calculation tools. The NCSS was designed for the development, testing and validation of automation systems for electric power distribution systems.
