摘　　要：考虑到多区域互联系统中信息交流可能存在障碍,传统潮流计算方法不再适用,本文提出一种基于边界节点灵敏度信息的分解协调潮流计算方法,对多区域互联系统在量测点处进行撕裂,切分为能够单独分析的多个子区域,基于边界节点灵敏度信息构建电压幅值协调方程和电压相角协调方程,且虑及子区域间固有角度差。该方法仅依据子区域内部信息和部分边界节点信息即可进行潮流计算,算例1和算例2证明了该方法的准确性和对大规模互联系统的有效性。Considering that the traditional power flow calculation method is no longer applicable due to the possible obstacles to information exchange in multi-area interconnected power system,a decomposition and coordination power flow calculation method is proposed based on the sensitivity information of boundary nodes.The multi-area interconnected power system is torn at the measurement points and divided into multiple sub-areas which can be analyzed separately.The voltage amplitude coordination equation and the voltage phase angle coordination equation are constructed based on the sensitivity information of boundary nodes,and the inherent angle difference between sub-areas is taken into account.The proposed method can calculate the power flow only based on the internal information of sub-areas and partial boundary node information.Example 1 and example 2 demonstrate the accuracy of the method and its effectiveness for large-scale interconnected power system.
