Abstract

As more and more distributed generation (DG) are added to the distribution network, the safe and reliable operation of the distribution network is challenged. Firstly, in order to quantify the benefits of energy storage improving distribution network reliability, a value model of energy storage improving distribution network reliability is established. Then, in order to calculate the load range that can be supplied by the energy storage when the failure occurs, a probability distribution model of the remaining energy storage when the failure occurs is established, and islands are divided according to the output of wind power and photovoltaic. Then, based on the sequential Monte Carlo simulation method and Latin hypercube sampling, the reliability of wind storage and distribution network is evaluated. Finally, the influence of different energy storage capacity on the reliability of distribution network is obtained through simulation calculation.
