Maximum charge station evaluation mathod in microgrid and system thereof

The present disclosure provides a maximum charge station evaluation method in a microgrid. The method comprises inputting system parameters of the microgrid; setting an initial value of the maximum number of charge stations to be the upper limit of binary search, and performing analysis of power flow; determining whether the maximum number of charge stations exceed the restrictions according to the limits of variation in voltage, loading, and three-phase voltage unbalance; when the maximum number of charge stations exceeds the restrictions, setting the present maximum number of charge stations as the upper limit, and updating the maximum number of charge stations according to binary search; when the maximum number of charge stations does not exceed the restrictions, setting the maximum number of charge stations as the lower limit of binary search, and updating the maximum number of charge stations, for performing analysis of power flow.
