摘要
对PJM电力市场进行了研究.PJM能量市场使用基于直流潮流的安全约束经济调度,节点边际电价(LMP)中不考虑输电损失.在PJM方法的基础上增加了关于多条支路传输功率之和的约束,提出了基于支路集的功率传输分配系数矩阵.应用该方法对某电网进行了试算,结果表明,这种方法能为市场各方提供正确的价格信号,可与固定输电权一起很好地管理拥塞成本,值得借鉴.
For the pricing of power transmission/distribution in China, the PJM power market is introduced as a reference and studied, in which the locational marginal price (LMP) with no transmission loss taken into account is calculated according to the security constrained economic dispatch (SCED) based on de-power flow. To adapt the actual need, the constraints on the sum of transmitted power of multiple branches are added to the original PJM model, and the power transmission distributed factor (PTDF) matrix is proposed for branch sets. To test the efficiency of the proposed approach, a calculation trial has been done using a mathematical model of a 500 kV network. The results showed that the approach can provide correct signals to all parties on power market and manage well the costs due to congestion with the fixed transmission right (FTR) used together.
