Challenges in Future Distribution Grids - A Review

Abstract

The integration of distributed generation facilities and large loads into the electric grid entails power quality issues. Large scale implementation of renewable and other distributed generation as well as relevant loads like heat pumps into the low and medium voltage grid does not longer allow ignoring the influence of those systems on power quality and stability. Grid codes for different regions started to implement the special re quirements introduced by distributed generation. Distributed generation is able to reduce but also to increase issues regarding network loading and stability or power quality. Optimised grid control, generator control as well as demand and supply side management are identified as suitable solutions for an optimised integration into the distribution grid.
