Modernization and Optimization of Traditional Substations for Integration in Smart Grid

This paper presents a proposition of an eco-design for the future Moroccan substation. The proposed design can enhance the efficiency of substation, reduce the area of substation construction and be environmentally friendly. The design is based on two technologies: the first one is Disconnecting Circuit Breaker which is a primary disconnecting device, the second one is Non- non-conventional instrument transformers used for measurements. Also, a proposition of retrofit to digitalize existed substations is given with a demonstration prototype.
