Abstract

Reducing technical energy losses in the distribution grid has a direct economic benefit for the distribution system operator and furthermore it can increase the grid hosting capacity. Part of the technical losses is due to reactive power in the distribution grid. The approach in this paper is to centrally calculate optimized configurations for local Q(V) control of grid-connected inverters, with the target to reduced technical losses in the low voltage grid. The preliminary assessment in this short paper shows that there is a potential of up to 19.8% loss reduction for a realistic low voltage feeder.
