Technical Strategies for Voltage Power Regulation in LV Distribution Networks
DOI:
https://doi.org/10.13052/dgaej2156-3306.3041Abstract
We report the integration of a novel voltage regulation strategy
in the inverter control algorithm for Dispersed Generation (DG) appli -
cations. The adoption of a decentralized voltage control based on local
curves allows the voltage profile to be controlled at the Point of Common
Coupling (PCC) of the generators and, therefore, the capacity of exist-
ing distribution networks to host more generation from renewables. The
work is focused on a low voltage distribution network and both the re-
active power modulation and the real power curtailment are considered
in the proposed local 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 in-
verter apparatus is evaluated. Secondly, the benefit of the control strategy
is analysed by experimental analysis in a test facility to verify the feasibil-
ity of voltage regulation in a real feeder.
