考虑网损和输电约束的发电竞价交易方法

采用非线性规划方法解决电力市场中机组多时段报价与发电计划问题。建立了考虑抽水蓄能电站的多时段发电计划模型，在排序的基础上考虑输电约束和网损对发电计划的影响，用非线性优化方法进行计算，得到满足报价和电网约束的最优发电计划。对一个6节点母线系统进行了多时段发电交易计划分析，结果显示电网输电约束和传输损失对发电计划产生影响，多时段发电计划优化能带来更大的全局经济利益。

A METHOD FOR GENERATION BIDDING AND TRANSACTION CONSIDERING TRANSMISSION LOSSES AND TRANSMISSION CONSTRAINTS

A new model for multi-period generation bidding and transaction in the electricity market is described based on thenonlinear formulation. Pump station is considered in the multi-period model. The effect of security constraints and1transmission losses on generation schedule is considered. Nonlinear programming is used to get the most profitable valueaccording to the power flow and the bids offered by plants. The transaction schedule for a 6-bus system with a pump stationis calculated to demonstrate the effectiveness of the proposed model. The results show that the security constraints andtransmission losses have important impact on transaction schedule, and by multi-period model the transaction schedule mayobtain more profitable value.
