As UPQC based on super capacitor energy storage costs a long time to compensate the power, the optimum energy control strategy is proposed in this paper. This strategy obtains the injection angle of the compensation voltage by PSO by analyzing the optimal stable power of UPQC. This strategy uses bi-direction DC/DC circuit to reduce the capacity of UPQC devices, which can extends the compensation time without increasing energy storage capacity and enhances operation economy. The control method is verified possible and effective by theoretical analysis, simulation and experiment results.
