In this paper an object-oriented model for an electrical grid based on the IEEE 34 node test feeder and the integration of this grid with photovoltaic systems on residential level; i.e. 230 V; is presented. The goal is to demonstrate the flexibility of using Modelica to simulate a grid model and to show how this model can be used to simulate the influence of a household power demand and photovoltaic generation on this electrical grid. The idea is to clarify the voltage problem that might occur when implementing a large amount of photovoltaic (PV) systems into a residential grid.
