Abstract:  This paper proposes a new reliability evaluation method for distribution system considering demand response. Firstly, we divided the peak-valley periods based on improved membership function and established a customer response model integrating time-of-use price and incentives. To improve the reliability assessment efficiency,  a clustering method based on threshold and minimum distance was proposed to generate annual load multi-state model. We applied the correlation coefficient matrix, Latin hypercube sampling and Cholesky decomposition to get the correlation sample of wind turbine generator output. Finally, the reliability analysis of active distribution network considering demand response can be realized by correcting the traditional reliability index based on island stable operation probability. Applying the proposed method to the reliability evaluation of example, the results show that the demand response strategy can improve the reliability and energy efficiency of grid.
