Abstract

The three-dimensional model of failure possibility is established based on operation state of elements, utility theory and probability theory, considering the dispatchers´ operation experience and sensitivity to the weather. Using this model, the risk indices of power system can be simulated and calculated. The online risk analysis software of power supply(RAPS) for regional grid has been developed, using AC-DC hybrid algorithm, by introducing some advanced technology, including parallel computing, dynamic node ordering optimization, matrix inverse optimization, etc. The software can supply dispatchers with real-time decision information.
