Quantification of emission reduction from electricity network with the integration of renewable resources

Integration of renewable energy resources into the electricity network is one of the strategies for overall emission reduction in the network. The quantification of emission offset from renewable distributed generation (DG) needs to be incorporated in planning to assess the effectiveness of integrating these resources from emission reduction perspective. In this paper, a numerical method is proposed for quantifying the emission reduction from distribution network with the integration of renewable resources by examining the coincident hours between the time varying nature of load and generation. The factors influencing annual emission reduction are also identified along with the use of energy curtailment strategy for emission reduction. Embodied emissions for energy from grid and renewable DG systems are also used for quantification of overall emission reduction. The proposed methodology has been tested on a practical distribution network and results are presented.
