Integrating photovoltaic generation into rural electricity networks

The project identified the opportunities and problems associated with integrating power from large numbers of small domestic photovoltaic (PV) installations into a rural electricity grid. A model analysed the technical limits of PV penetration and the benefits and problems for customer and network suppliers. The results will help in network planning when PV becomes a more established technology.

The researchers developed models to simulate the effects of PV integration into a rural electricity grid. The results of the analysis determined technical limits for PV penetration at the distribution level. It also assessed the impact of the presence of many PV sources on the network, in particular identifying the effects on harmonic disturbance. Theoretical analyses and simulation of results identified a limit value for PV penetration of 150 % (the ratio between installed PV capacity and the total load). This limit value could not be tested practically because there are no local grids yet established that have such a high load of PV.
