Abstract

We report the integration of a novel voltage regulation strategy in the
inverter control algorithm for Dispersed Generation (DG) applications.
The adoption of a decentralized voltage control based on local curves al -
lows the voltage profile to be controlled at the Point of Common Coupling
(PCC) of the generators and, therefore, the capacity of existing distribution
networks to host more generation from renewables. The work is focused
on a low voltage distribution network and both the reactive power modu-
lation and the real power curtailment are considered in the proposed lo-
cal strategy. Both numerical and experimental analysis are necessary in
order to test and validate the proposed voltage control strategy. Firstly,
the performances of the proposed control are tested by a numeral analysis
and the impact on both the electrical system and the inverter apparatus
is evaluated. Secondly, the benefit of the control strategy is analysed by
experimental analysis in a test facility to verify the feasibility of voltage
regulation in a real feeder.
