Abstract

With the increase of dimensionality and uncertainty in modern power grids, the traditional reliability evaluation methods have bottlenecks in computational performance due to the need to repeatedly solve the optimal system tides. In this paper, a reliability evaluation method based on convolutional deep network combined with importance sampling is proposed to improve the computational efficiency of a composite power system containing distributed power sources. The method takes samples consisting of distributed generating units, transmission capacity and total load as inputs, and utilizes the convolutional property for feature extraction of the topology incorporated into the power system. Importance sampling is used to reduce the fluctuation of the reliability evaluation process triggered by the uncertainty in the output power of distributed PV and wind turbines. The convolutional neural network is used to predict load shedding in the sampled system states, and the reliability index consisting of the expected system power shortage supply, probability of power shortage and frequency of power shortage is evaluated with the minimum load shedding. The experimental results on the IEEE RTS reliability test system show that the proposed method is effective in calculating the integrated system reliability index.
