Impact of distributed generation capacity on losses

The introduction of distributed generation (DG) onto distribution networks has a significant effect on losses. This effect cannot be characterised as detrimental or beneficial but is dependent on the allocation of DG on each distribution network section. Here the impact of DG on losses has been modelled, facilitating a unique approach to the allocation of DG. This approach has been implemented and tested on sample sections of distribution network and results are presented showing the optimal allocation of DG which improves the efficiency of energy delivery on the distribution network. The temporal variations of load and generation are simulated, illustrating that the allocation improves the efficiency throughout a year. The effect of different plant mixes is also simulated showing that the efficiency of energy delivery is dependent on the load factor and operating characteristic of the plant
