Smart grid communication: Requirements and SCADA protocols analysis

Nowadays, several smart grid solutions have been proposed to improve electrical power systems. These solutions are based on a stronger, faster and more reliable network communication. Analyzing communication requirements is one of the first step in deploying a smart grid solutions, such as new applications and systems. However, this is normally not taken into account as electrical power systems and communication networks are treated as two separate fields. This paper therefore relates smart grid communication requirements and the need to make the deployment possible. The most used SCADA protocols, such as MMS and DNP3, are discussed. The most important points are highlighted aimed at providing resources to a smarter choice for smart grid communication.
