适于多种电源接入的分散协调AGC控制方法

Decentralized Coordinated Automatic Generation Control Method Adapted to the Accessing of Multi energy Sources

  • 摘要: 以风电、径流式小水电为代表的间歇性能源已在电网大规模接入,此类能源发电的不确定特性使得电网在调频方面临新的挑战。本文提出了一种适应于多种能源接入的分散协调自动发电控制方法,该方法在AGC控制的过程中考虑多种电源及负荷分布特点,通过不同类型机组在部分局部区域协调配合,以改善电网频率控制性能,同时减小集群间歇性电源有功波动造成的影响。文章从分散协调控制方法、协调控制策略等方面介绍了针对多种能源接入后AGC控制的适应性方案。采用某省级电网的实际模型及数据进行仿真,验证所提方法的有效性。

     

    Abstract: With the accessing of intermittent energy represented by wind and small hydropower in large scale, the power grid will face the new challenges in frequency regulation and peak load regulation due to the uncertainty of energy generation. If original automatic generation control is still applied to provincial power grid, it will be difficult to solve such problems as increasing pressure on frequency regulation in the whole power grid, AGC control performance degradation and transmission congestion. In this paper, a decentralized coordinated automatic generation control method is presented, in which the characteristics of multi energy sources and load distribution are considered during AGC control, and different type units are coordinated in local areas to improve frequency control performance of power grid, and to reduce the impact caused by the active power fluctuation of intermittent energy sources. The adaptive scheme of the AGC control for power grid with intermittent energy sources accessing is introduced from the aspects of the decentralized coordinated control method, coordinated control strategy and so on. The real AGC model and data of a provincial power grid are taken as example case, and the results verify the validity of the proposed method.
