Disscussion on Decision Making Mode and Support System of Power Provider Group

It is electricity market, especially regional electricity market marked by opened mainly in generation side, that alters the production mode of power provider from planed mode to bidding mode in order to realize their profit objective. For power provider group, which own many power plants in electricity market and may achieve more market information and production information than one plant, it is of great value to enforce supervision on their power plants and induce them take part in electricity more actively to achieve maximization of profit and reduce interior competition. Considering the intact relationship between bidding decision-making mode and deployment of its supporting technical system, this paper introduced three typical bidding decision-making mode such as decentralized deployment and decentralized decision-making, centralized deployment and decentralized decision-making, and centralized deployment and centralized decision-making mode to meet demands listed above of power provider group. Then analyzed the characteristics of each decision-making mode and correspondent supporting system. The analysis results indicate that the bidding decision-making mode would translate from decentralized deployment and decentralized decision-making to centralized deployment and decentralized decision-making, and to centralized deployment and centralized decision-making mode eventually.
