Sensitivity Analysis of Distributed PV-fed AC Distribution Network Supported with Distributed Energy Storage Systems

With the severe climatic changes it became essential to reduce greenhouse gas emissions. This can be achieved by substituting fossil fuel-depending energy sources with green renewable energy sources. Despite having lot of merits, the extensive installation of renewable energy at the low voltage grid has led to instability in the grid voltage due to dynamic changes in the generation-consumption relationship. Therefore, dynamic solutions became needed to intervene and restore the grid voltage stability. This paper shows the importance of using distributed energy storage units in the low-voltage grid to restore its voltage stability.
