Abstract

Available transfer capability (ATC) has become an important indicator in the power system operation and planning. In order to better guide dispatchers to make decisions, this paper focuses on improving integrity of the calculation model and robustness of the algorithm. Based on the analysis of power incremental directions, constraints checking and system instable risk on ATC, a fast calculation algorithm for dynamic ATC is presented. Through improving the repeated power flow (RPF) method, this calculation framework is applicable in bulk interconnected grid. The online application of developed software in practical power grid verifies the validity and applicability of the proposed approach.
