An integrated control for overvoltage mitigation in the distribution network

Increasing share of distributed renewable energy sources (DRES) in the distribution network raises new operational and power quality challenges like overvoltage in the network feeders. Such power quality challenge limits the penetration of DRES in the distribution network. This paper addresses a communication independent droop control, a communication dependant fast control and proposes an integrated control for mitigating overvoltage in the LV distribution network. The two layer integred control consists of droop control and fast control. Proposed integrated control tries to equalise power curtailment, among inverters in a radial networ
