چکیده

In a deregulated electricity market, market participants use optimal bidding strategies in order to maximize their individual profits, due to the uncertainty and dynamic of electricity market, players’ optimal bidding strategy is not determined easily. Power markets have two objectives. The first which is the Maximization of their profit and the second is their utilization rate. It is essential for players to identify complex behavior by learning through a continuous exploiting and exploring process. Reinforcement learning is a good way to make a decision in these incomplete information markets. In this paper agent-based simulation is employed to study the incomplete power market operation under pay-as-bid pricing market. The market is considered SFE model that players proposed both bids and powers in their suppliers’ functions. Power suppliers are modeled as adaptive agents capable of learning through the interaction with their environment, following a Reinforcement Learning algorithm. The SA-Q-learning algorithm, a slightly changed version of the popular Q-Learning, is used in this Paper. In this paper new state-action definition are proposed. The results of proposed state-action method on five bus power systemare compared with different state-action definitions and the superiority of this definition in two different cases is shown

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.
