中文摘要：

针对未来高渗透率的微网结构中，大量民用单相负荷的供电会导致微源本地不平衡问题，分别利用跟踪法、补偿法和滑模控制3种控制策略进行研究。选择每种控制策略的控制传递函数，并进行相关理论推导，根据其控制策略搭建各系统模型，调整控制参数得出每种控制的理想控制结果。针对每种控制策略，在相同的硬件结构和控制参数情况下．进行了微源本地带平衡负荷和不平衡负荷的研究。根据结果分析比较得出：3种控制方法均能实现在平衡负荷和不平衡负荷情况下的理想控制；从控制效果看，补偿法有较好的控制性能：从控制方法上看．滑模控制方法更加简单实用。

英文摘要：

Large single-phase load may cause load imbalance in future micro-network structure with high penetration,which is studied by three control strategies：tracking method,compensation method and SMVSC （Sliding Mode Variable Structure Control）. The control transfer function is selected for each strategy,the related theory derived and the system model set up. The ideal control result is obtained by adjusting control parameters for each strategy. The micro- source load,balanced and unbalanced,is researched with every control strategy with same hardware structure and control parameters. Results show that,all three control methods achieve a good control effect for both balance and imbalance loads. However,compensation method has better control performance while SMVSC is more simple and practical.
