摘　　要：研究了考虑输电阻塞影响的发电商最优报价策略问题,建立了求解该问题的2层优化模型,第1层是基于竞争对手报价的发电商利润最大化模型,第2层是基于灵敏度分析的以阻塞费用最小为目标的发电商出力调整模型,并采用遗传算法对其进行求解。以IEEE14节点系统为算例的分析结果表明,本文提出的方法可用于指导发电商制定报价策略。The authors research the optimal bidding strategy of generation company with transmission congestion considered and build a two layer optimal model to solve this problem. The first layer is a profit maximization model for generation company in which the biddings of competitors are taken into account; the second layer is a sensitivity analysis based output regulation model of power generation company in which the minimum congestion cost is taken as objective, and this model is solved by genetic algorithm. The simulation results of applying the proposed method to 1EEE 14-bus test system show that the proposed method can be adopted to guide the drafting of bidding strategy.
