Optimal allocation of renewable enegy resources for minimising emissions in the distribution network
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.
