Distributed generation in the Dutch LV network - self-supporting residential area -

A self-supporting residential area is seen as an alternative operational approach of power supply in low voltage (LV) networks. The intention of the new approach is to exploit the advantages of distributed generation (DG) and avoid the difficulties, that come with DG when implemented in the distribution network, by balancing power supply and demand efficiently in the area that can easily be controlled and isolated from the upper grid. This case study verifies statements about the alternative operational approach by calculating reverse power flow, voltage levels, system losses, cable and transformer loads of a well-designed self-supporting residential area in the low voltage network containing combined heat and power (CHP), photovoltaic (PV) arrays and storage devices with a simulation program dasiavision network analysispsila. It appeared difficult to create a self-supporting residential area along seasons without being inferior in the parameters as stated above.
