Integration of renewable Distributed Generation (DG) into the
distribution networks is one of the effective ways to ensure
emission reduction with the added benefits of network
support and transmission and distribution system expansion
deferral. Emission reduction by renewable DGs mostly
depends on the generation technology, size and type of DG
units and curtailment of fossil fuel based grid energy. This
paper proposes a strategy for evaluating the size and type of
renewable DG and determining the best mix of different
renewable DG technologies by minimising primary and
operational emissions without violating network constraints.
A methodology based on time sequential optimisation is
proposed for maximising annual emission offset considering
the time varying demand and generation with different
penetration of renewable resources into distribution networks.
The proposed technique is tested on a realistic distribution
feeder with different scenarios and results are presented.
