A power system analysis model with consideration of environmental factors

Abstract

Power System will be inevitably influenced by the environment during its operations. However, little attention is paid to this aspect in traditional power system analysis methods, which can cause errors in the calculation results and even endanger the security of the system. Through comprehensively analyzing the thermal balance and temperature ascending process, this paper sets up an environment-considering power system analysis model, which can determine the security risk by supervising the temperature of the transmission line during the operation. Finally, a scenario of 5-bus system is provided to test the rationality of the model.
