چکیده

The Imperialist Competitive Algorithm (ICA) has been recently introduced. This algorithm that is based on a socio-politically inspired optimization strategy has shown goodconvergence rate to achieve global optimum for different optimization problems. In a deregulated electricity market, reactive power suppliers as one of six ancillary services areeligible for financial compensation. In this paper, a reactive power market that is decoupled from the active power markethas been solved using the ICA. Minimizing energy losses and total payments to reactive power providers by the systemoperator are considered as the objectives of the introduced reactive power market. The corresponding optimization problem is a non-convex Mixed-Integer Non-LinearProgramming (MINLP) problem. Here, an algorithm is introduced that uses the ICA to change the MINLP problem to aseries of NLP sub problems. The IEEE 30-bus test system is used to demonstrate some aspects of the application of the ICA on the reactive power market problem. The results arecompared with those obtained by Genetic Algorithm (GA) showing that the ICA convergence rate is more than GA

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
