基于市场报价的阻塞管理模型及内点法实现

提出了一种电力市场下解决阻塞问题的新方法，它可以根据市场报价同时调整实时平衡市场下的发电机出力和削减部分短期双边合同量。建立了阻塞管理的非线性数学模型，应用改造的非线性原对偶内点法最优潮流求解以上模型，计算出的节点实时电价体现了如何在各用户中分摊阻塞管理费用。算例表明，该方法可以根据市场参与者的报价得到最优的调度方案，利用节点电价指导用户调整用电计划，从而有效地解决了阻塞问题。

A BIDDING BASED MODEL OF CONGESTION MANAGEMENT AND ITS ALGORITHM VIA INTERIOR POINT METHODS

A new approach of real- tim e congestion management under deregulation environm ent is presented in this paper,in which resources in both balancing m arket and forward markets can be efficiently dispatched.The nonlinear m odel of a modified optim al power flow OPF is proposed to implement such an approach and a prim al- dual interior point nonlinear programm ing method is applied to solve the optim ization problem.Nodal price for the real- time congestion m anagem ent is analyzed to show how to allocate the cost of congestion management among the m arket participants.Num erical exam ples illustrate that the approach can optimize the re- dispatching according to the bids subm itted by the markets participants,and instruct the consumers to adjust their dem ands with the spot prices.Therefore the transmission congestion can be efficiently reduced through the proposed approach.
