摘要
Abstract
From the perspective of entropy theory, the transfer entropy of power flow model was improved by taking the distribution of transfer power flow and loading rate of transmission lines into consideration. An algorithm of ice-melting preventive control was proposed for power system with the consideration of improved transfer entropy of power flow. This method added the improved transfer entropy of power flow into the preventive control model as constraint condition, regarding the adjustment of generator output as the key control measure. The simulative result of IEEE 30-bus system verifies that by taking the preventive control strategy from this method, the impact of breaking line to power system is greatly decreased, and the system comprehensive severity is down to a relatively low level. The security of power system in ice disaster is improved.关键词
