摘要(Abstract)：

微网中负载与电源类型多样,电能质量指标可能会不完全满足要求,为此提出了一种微源并网逆变器参与微网电能质量控制的补偿策略。给出了一种基于熵Shapely赋权的电能质量综合评估模型,该方法以熵权计算为基础,利用Shapely理论对权重进行调整,针对不同的样本点赋予不同的权值,避免了所有样本点采用统一权重值而无法对具体样本点的突出问题进行重点补偿的问题;提出了以实现并网点电能质量综合指标最优为目标的补偿算法,并给出基于拉格朗日乘子法的求解结果;逆变器除传送有功功率以外,还可根据微网的电能质量情况对负载谐波、无功和不平衡电流进行跟踪补偿。PSCAD/EMTDC仿真结果验证了所提策略的有效性。
