Abstract

The Ultra High Voltage power system plays an important role in alleviating the energy crisis. However, due to the high voltage level and complex operation, it will bring disaster to the system once the power grid fails, causing cascading failures and large area power outages. In this paper, we study the stability analysis method of AC/DC Ultra High Voltage power system. Based on setting fault scenarios and BPA simulation, we introduce risk assessment model and set up a series of indexes, including the low voltage risk, the unit angle difference risk and frequency instability risk, to assess the system stability. Compared with the traditional reliability analysis method, this paper combines the probability of the accident and its consequences, and links the risk and benefits, which can quantitatively reflects the safety index of the system. Therefore, it is more applicable in stability analysis for complex AC/DC Ultra High Voltage power system.
