Utilising observability analysis to cluster smart inverters on secondary circuits for residential deployment

As residential customers continue to connect distributed energy resources (DERs) with smart inverters unto distribution systems, distribution engineers face new challenges of accurately modelling residential smart inverters for distribution system optimisation. Depending on the coordination strategy, the impact of these DERs can represent a positive contribution to the system operation. However, if the coordination strategy does not consider the interaction between DERs and the distribution system for clustering them, the distribution system integrity can be compromised. This study describes an approach to group smart inverter photovoltaics (PVs) deployed within a secondary circuit (low-voltage system) to enable the correct monitoring and control of these smart inverters. It further explains the process used to coordinate clustered smart inverter PVs to enhance distribution operation optimisation.
