Embodiment Construction

[0027] Since the active distribution network contains renewable energy (wind power, photovoltaics, gas turbines, diesel units), energy storage elements, and electric vehicles, the number of states in the active distribution network increases sharply compared with the traditional distribution network. The Monte Carlo simulation method cannot be applied to the reliability analysis of active distribution networks. A method for reliability analysis of active distribution networks based on pseudo-sequential Monte Carlo simulation is proposed. This method uses non-sequential sampling simulation method to Reduce the time and memory used in the simulation, and use the sequential simulation method when sampling to the fault, which improves the accuracy of the reliability data obtained; and flexibly use the system state transition sampling during the sequential simulation to treat the system as a whole, The complicated process of sampling every component is avoided. At the same time, th...
