　　基于与公网连接的微网系统，提出了一个功率分担和潮流控制的技术方案。公网配电系统通过一套连续逆变器与微网相连。在此控制策略中，系统可以根据微网中的功率需求，运行在两种不同的模式下。本文还提出了一种微网中分布式电源的配置方法，可以在并网或者孤岛运行方式下实现负载的分担。通过各种运行情况的仿真，考察了所提出的控制策略的正确性和有效性。在PSCAD中完成了微网系统的建模以及仿真。

This paper proposes a power sharing and power flow control technique for a utility connected micro-grid. The utility distribution system is connected to the micro-grid through a set of back-to-back converters. In the proposed control strategy, the system can operate in two different modes depending on the power requirement in the micro-grid. An arrangement between DGs in the micro-grid is proposed to achieve load sharing in both grid connected and islanded modes. The efficacy of the proposed control arrangement has been validated through the simulation for various operating conditions. The model of the micro-grid power system is simulated in PSCAD.
