Dynamic economic emission dispatch with loss heat optimization for a micro-grid smart Micro Grid

摘要

This paper presents a comprehensive formulation for dynamic economic emission dispatch with loss and heat optimization scheme of a MicroGrid (MG) with utility participation. The projected problem is framed as a nonlinear inhibited multi-objective optimization problem. The proposed problem takes into consideration the process and upkeep cost, loss, heat as well as the emission reduction of noxious gases which are harmful to nature. With the rapid depletion of fossil fuel energy resources, increasing cost and universal emphasis on reducing emissions, impetus is being given for significant contribution of renewable energy sources. The MG technology is hence taking pace with the objective of improvement in efficiency & reliability and enabling incorporation of distributed energy resources (DER). Multi-objective optimization problem is a multifaceted task and traditional methods do not work fit in real-world ambiguous situation. This paper presents a technique based on Weighted SumTime-Varying Differential Evolution (TVDE) for simultaneous optimization of two of the four objectives i.e. Cost, Emission, Heat and Loss, in a micro-grid. The suggested approach is applied on a 5-Distributed Energy Resources and 14-Bus radial micro network with utility participation.
