Reliability assessment of distribution network considering the randomness of distributed generation

This paper studies the reliability evaluation algorithm of power distribution network with distributed generation. The randomness of the output power of photovoltaic power generation and wind power generation is studied firstly. According to the randomness of the output power of distributed generation. By Latin hypercube sampling, the reliability evaluation model of distribution network which considers the randomness of distributed generation is established. According to the importance of load, this paper builds an optimization model of islanding division in the power distribution network with distributed generation. On this basis, combining with the analysis of network topology, the reliability evaluation algorithm of power distribution network with distributed generation based on Monte Carlo timing simulation method is proposed. Finally, by using the proposed model and algorithm, this paper makes a simulation calculation to the main feeder F4 of IEEE RBTS Bus6 system, and verifies the validity and practicability of the model and algorithm.
