The adoption of nanogrids by electricity consumers has been increasing in many countries. Consumer units have been deploying small-scale renewable energy generation with or without energy storage systems (ESS). Electrical distribution system (EDS) operators will have to adapt their networks in order to fulfill the needs regarding a rising insertion of grids in nano scale. In this context, knowing the effects of a massive nanogrid penetration is fundamental for proper power system planning and operation. In the light of such need, this paper presents a methodology to model the massive integration of different nanogrid topologies into distribution systems. Considering seasonality and different penetration scenarios, nanogrids are allocated on a secondary distribution system which are connected to a primary system. Results show that the primary feeder may have a daily consumption reduction of up to 15% while its technical losses may decrease by 23 %.
