The global mega trends are changing the industries including the power sector. The rapidly growing technology is a key megatrend impacting all the industries. In power sector, among other technological advances, smartening the grid is a hot topic. Searching the literatures, several definitions can be found for smart grids. They can be summarized as: Adding intelligence over energy chain to generate, distribute and consume energy in more efficient and secure way. In fact, smart grid is multidimensional actor. A wildly used illustration for this multi-dimension is the Smart Grid Architecture Model (SGAM) defined by EU Smart Grid Coordination Group. In this paper, we review this model and enhance the reader’s insight by providing a mapping of these dimensions to the known power systems. The operation and control systems for energy transmission and distribution will be classified and state-of-art technologies in each area will be highlighted. In continuation the market trends and advances in Distributed Energy Resources (DER) and Smart Meter Infrastructure (AMI) will be reviewed. The paper will conclude with the challenges and opportunities that smart grids stakeholders such as TSO and DSO companies and end users are facing with the aim of providing futuristic guidelines.
