A Load-Shedding Model Based on Sensitivity Analysis in on-Line Power System Operation Risk Assessment

摘要: The traditional load-shedding models usually use global optimization to get the region, which will cause multiple variables, huge computing scale and other problems. This makes it hard meet requirements of timeliness in on-line power system operation risk assessment. In order solve problems present models, a model based on sensitivity analysis is proposed this manuscript. By calculating each branch bus, collection buses have remarkable influence reducing flow over-load branches obtained. way, turned local optimization, can narrow solution range. comprehensively considering importance load bus adjacency principle regarding electrical coupling relationship, established minimum value reduction from different kinds buses, solved by primal dual interior point algorithm. end, cases IEEE 24-bus, 300-bus multi-node systems are simulated. correctness effectiveness demonstrated simulation results.
