Collaborative evolution-based grid-connected converter harmonic damping algorithm

The invention relates to a collaborative evolution-based grid-connected converter harmonic damping algorithm, and the algorithm is suitable for coordination and optimization treatment of harmonic waves of each node voltage of a distribution network system with distributed power supply access. The algorithm comprises the following steps of establishing a constraint-containing collaborative evolution algorithm optimization model; solving the constraint optimization problem through the collaborative evolution algorithm, and processing constraint conditions by using a penalty function method; andsolving the optimal harmonic wave resistance of the grid-connected inverter based on a hybrid strategy collaborative evolution algorithm. Based on the collaborative evolution algorithm, the equivalentharmonic wave resistance of the inverter is dynamically adjusted, so that the node harmonic wave voltage level of the whole distributed distribution network system is effectively lowered. 本发明涉及种基于协同演化的并网变流器谐波阻尼算法，适用于对含分布式电源接入
