This paper presents a decentralised control scheme of a distributed generator to actively respond to voltage and thermal issues in a distribution network. An operation scheme providing a local voltage control by adjusting the reactive power output of the generator is proposed. Generation curtailment is employed to relieve overloaded lines as well as to support the voltage regulation scheme. These control mechanisms do not require sophisticated communication links and hence can avoid high investment costs that would be required for a centralised measurement and communication system. Results show that the proposed schemes respond effectively to the voltage and thermal constraints, allowing further penetration of generation capacity.
