Fast Calculation Method for Continuous Power Flow of Microgrid Based on Levenberg-Marquardt Algorithm

There are possible non-convergence problems at load power critical value while using conventional continuous flow methods. Generally, the step control method is used in calculation to perform small steps convergence value, and this sacrifices speed of although accuracy high. In paper, Levenberg-Marquardt algorithm search for firstly, after that designed fast finding with known which takes into account computational efficiency. The case shows microgrid based on proposed paper can guarantee effectively improving speed, suitable online real-time evaluation voltage stability preventive aided decision isolated high requirements real-time.
