An efficient bi-objective approach for dynamic economic emission dispatch of renewable-integrated microgrids

Abstract To overcome the challenges of conventional power systems, such as increasing demand, requirements stability and reliability, integration renewable energy sources, concept microgrids was introduced is currently one most important solutions for solving mentioned problems. Generally, have two operating modes, namely grid-connected islanded modes. Based on literature its unique characteristics, mode more challenging than other one. In this paper, a new self-adaptive comprehensive differential evolution (SACDE) algorithm proposed economic load dispatch (ELD) combined emission (CEED) problems, achieving optimal consumption in isolated microgrids. Initially, SACDE employed ELD problem single-objective function, meaning that operational cost just considered objective thereby, resources are scheduled accordingly. Then, multi-objective platform based also to solve CEED problem. It means functions, including emission, simultaneously optimized. For evaluating performance method, three different scenarios under various cases considered. According results, when single function (cost minimization) problem, it has better methods. terms bi-objective scheme minimization), significantly superior price penalty factor technique which frequently used previous studies.
