Abstract

Smart grids with interoperability improve grid reliability by collecting system information and transferring it to an energy management system and associated applications through a seamless end-to-end connection. To achieve interoperability, it is required to exchange the semantic information within the different domains. The international electrotechnical commission has established the Common Information Model (CIM) tool, which is a standard application programming interface for the exchange of semantic information in power systems. CIM provides a robust framework for accurate data sharing, merging, and transformation into reusable information. However, as CIM provides a basic framework for information exchange, various practical issues arise in establishing an energy management system capable of exchanging information using CIM. This paper aims to offer a comprehensive understanding by summarizing and categorizing the research on the practical use of CIM for interoperability in smart grids. Many papers are analyzed and the issues are classified into CIM extension, harmonization, and validation to address the issues that arise when establishing an integrated information exchange system.

Highlights

Interoperability refers to the seamless, end-to-end connectivity of hardware and software in domestic appliances through the transmission and distribution system to the power source, enhancing the coordination of energy flows with real-time flows of information and analysis
By analyzing the preprocessing methods for effective validation and the validation concept according to the format in which the model was represented, we summarize the interoperability verification methods using Common Information Model (CIM)
Information exchange interface design is vital for establishing interoperability in smart grids to collect and exchange data between the energy management systems (EMS) and applications

Summary

Introduction

Interoperability refers to the seamless, end-to-end connectivity of hardware and software in domestic appliances through the transmission and distribution system to the power source, enhancing the coordination of energy flows with real-time flows of information and analysis. The interoperability improves the grid reliability by collecting more useful information and transferring it to the operators and equipment to improve and protect the grid operations [1]. To achieve interoperability in a smart grid, it is required to exchange semantic information within the different domains [2]. Information Model (CIM) tool, which the International Electrotechnical Commission (IEC) adopted as IEC 61970-301 [3,4]. CIM provides a powerful and flexible integration technology using standard. The architecture is fundamentally vendor-neutral, as it is based on open standards [5,6]
