Abstract

As distribution systems move towards being more actively managed there is increased potential for regional markets and the application of locational marginal prices (LMPs) to capture spatial variation in the marginal cost of electricity at distribution level. However, with this increased network visibility can come increased price volatility and uncertainty to investors. This paper studies the variation in LMPs in a section of the south west of England distribution network for current and future installed capacity of distributed generation. It has been shown that in an unconstrained network, spatial LMP variation (due to losses) is minimal compared to the temporal variation. In a constrained network, a significant increase in LMP volatility was observed, both spatially and temporally. This could bring risk for generators particularly if they become stranded in low price areas, or flexible demands facing a drop-off in return when constraints are removed.
