Abstract

This paper demonstrates the potential benefits of utilisation of distributed generation (DG) in reducing network losses and of automatic post-fault actions in maximising DG output. A number of quantified examples are presented, based on simulations, for two actual distribution networks in the UK using reconfiguration of normally open points and inter-tripping of generation. The results show that a noteworthy reduction in losses might be achieved, and demonstrate the extent to which the actual results depend on the configuration of the network, the level of demand and the amount of DG in operation. It is argued that the benefits in terms of reduction of losses and maximisation of DG output are significant enough and the automation technology mature enough to justify investment in appropriate metering, communication and control, but that current commercial arrangements often prevent appropriate automation measures from being implemented
