This paper suggests a method based on stochastic multi-objective modelling for optimally siting and sizing
of distributed generations and capacitors and simultaneously network reconfiguration, in order to take
more advantages of recent developed technologies. With respect to the widespread effect of uncertainties
of load forecasting and market price, some strategies must be devised so as to well incorporate them into
the problem. The mentioned problem can be regarded as a multi-objective optimisation problem for which
NSGA-II accompanied by fuzzy set theory are chosen. The main aim of DisCo is to provide highly reliable
power at the lowest possible costs. Besides, voltage deviation and voltage stability as the criteria of power
quality in distribution networks and emission pollutant reduction are treated as independent objective
functions. Eventually, to validate the effectiveness of the proposed scheme, simulations are carried out
and the results are compared to the initial configuration.
