The invention provides a load balancing method. The method comprises the following steps: step one, acquiring a current value and a voltage value at each of a power source end and a load end; step two, computing the corresponding active factor, inactive factor, power factor and load rate according to the current value and the voltage value; step three, controlling a static var compensator to perform the current compensation according to the power factor; step four, computing the optimal output power through an optimal control algorithm according to the active factor, the inactive factor, the power factor and the load rate; step five, controlling a voltage regulator to output the optimal output power; step six, repeating the steps one to five. The invention further provides a load balancing device and an electricity driver. Through the adoption of the method provided by the invention, the input power of a motor can be dynamically adjusted, the capacity of a transformer is reduced, the required input power of t
