Abstract
Distributed generator (DG) has several advantages over the large-scale power plant and is expected to complement the power system. In this paper, we focused on the locational flexibility and short lead time as advantages of DG, and examined the influence of uncertainty of demand growth on the optimal locational configuration of DGs in the transmission network and on the amount of installed DG.
The results indicate that the total capacity of installed DGs is greater under uncertain demand growth than under certain growth. And it is also indicated that under the uncertainty, the installed DG capacity is distributed generally in proportion to the growth of the local loads. The latter finding suggests that the expected load growth at each point could be a useful indicator for screening candidates of locational configurations of DGs.
