基于上下游市场联动的燃煤电厂两阶段决策模型
A Two-stage Decision Model for Coal-fired Power Plants Based on Upstream and Downstream Market Linkages
摘要
Abstract
With the sharp fluctuations in bulk energy prices and the impact of new energy on the grid,the operation of coal-fired power plants,which are indispensable at this stage,is difficult.While optimizing the management and control of upstream fuel procurement and storage costs,the linkage decision-making for the downstream power market bidding and grid connection can improve the living space of thermal power generation enterprises under the carbon peak and carbon neutrality background to a certain extent.Aiming at the problems of inconsistent decision-making cycles in the linkage between upstream and downstream markets and the fact that the fixed power generation cost quadratic curve cannot reflect the changes in power generation costs,this paper proposes a two-stage optimization decision-making model for coal-fired power plants based on the linkage of upstream and downstream markets.First,the linkage model of upstream and downstream markets of coal-fired power plants is proposed.Then,a two-stage decision-making model of coal purchase and bidding strategy is established,and the influence of conditional value-at-risk on decision-making is discussed.Finally,the coal-fired power plant A is used to analyze an example and verify the validity of the two-stage decision-making model.The calculation example shows that the two-stage decision-making model proposed in this paper can solve the above problems and maximize profits.关键词
