基于潮流越限量的阻塞费用分摊方案研究

Research on congestion cost allocation based on exceeding power flow

提出一种基于潮流跟踪原理,在双边交易模式下按阻塞线路上各交易导致线路阻塞的潮流越限量占线路潮流总越限量的比例分摊阻塞费用。由于线路潮流在达到线路容量上限之前,不存在阻塞,各交易成交量的变化不对阻塞承担责任。在达到线路容量上限后,交易量的增加使得线路发生阻塞,则这部分潮流增量就应承担阻塞的全部责任。采用该方法分摊阻塞成本,能准确地反映引起阻塞的责任,并公平地对待各市场参与者,消除阻塞对市场的不利影响。4节点系统算例表明该算法可行。

The congestion cost allocated to the bilateral transaction is proportional to the contribution to congestion of each transaction on a flow-tracing basis. Before the power flow reaches line maximum transmission capability,there is no congestion and congestion cost. The exceeding power flow,which results in congestion,should take on whole responsibility. The proposed method reflects exactly the congestion responsibility and treats the market participants fairly to eliminate the impact of congestion on the market. A 4-bus system is presented to show its validity and efficiency.
