Reliable and scalable communication technologies are required to securely integrate and utilise the flexibility offered by different smart grid solutions. Smart secondary substations can play a critical role in enabling the flexibility services for the DSO with more monitoring and control functions being deployed at these substations. However, there are a number of challenges associated with the deployment and integration of communications to enable future DSO functions. This paper defines the key requirements for future secondary substation communications and provides a number of recommendations to address future operator needs. A case study related to the deployment of a Smart Transformer for better utilisation of network assets and voltage regulation is presented to illustrate the applicability of aforementioned requirements.
