【摘要】：多个微电网互联成微电网群运行,在提高微电网可靠性及降低发电成本方面有巨大潜力,然而传统比例下垂控制未考虑不同类型分布式电源的发电成本差异,易导致系统高发电成本。提出计及线路损耗的自治型微电网群分布式经济控制方法,通过实现各分布式电源线损边际成本一致,有效降低系统发电成本,并提出利用虚拟边际成本将节点电压控制在合理范围内。该方法不存在中心控制器,基于邻居控制器间的信息交流,通过一致性算法迭代获取控制所需全局状态信息,可靠性高。利用Matlab/Simulink以及OPNET仿真平台验证了所提方法的有效性。
[Abstract]:It has great potential to improve the reliability of microgrid and reduce the generation cost, but the traditional proportional droop control does not take into account the difference of generation cost of different types of distributed generation. This paper presents a distributed economic control method of autonomous microgrid group considering line loss. By realizing the consistency of marginal cost of distributed power line loss, the generation cost of the system can be reduced effectively. The node voltage is controlled within a reasonable range by using virtual marginal cost. There is no central controller in this method. Based on the information exchange between neighbor controllers, the global state information of the control is obtained iteratively by the consistency algorithm. The reliability of the proposed method is high. The effectiveness of the proposed method is verified by using Matlab/Simulink and OPNET simulation platform.
