基于PMU及和声搜索算法的新能源配电网负载模型研究
发布时间：2018-08-22 13:26
【摘要】：文章提出了一种基于同步相量测量(PMU)数据并用于估算配电网负载模型的和声搜索算法(HSA)改进分布式测量。由于近年来分布式发电的发展,燃料电池和风力涡轮机等的接入使得配电网的拓扑结构进一步复杂。因此,需要通过改变传统的分布荷载模型来克服这个问题。估算模型不仅要在网络正常条件下和真实模型作出相同的反应,而且在网络故障和瞬态条件下是有效的。本中,负荷模型及其相应的方程已被修改。双反馈感应电机(DFIM)的参数估算以及在网络频率变化情况下负载电源的可靠性都包含在模型中。该模型在Matlab/Simulink环境下进行仿真验证该算法的有效性。
[Abstract]:In this paper, a harmonic search algorithm based on synchronous phasor (PMU) data and used to estimate the load model of distribution network is proposed. (HSA) is used to improve the distributed measurement. Due to the development of distributed generation in recent years, the connection of fuel cell and wind turbine makes the topology of distribution network more complicated. Therefore, it is necessary to overcome this problem by changing the traditional distributed load model. The estimation model should not only react the same as the real model under the normal condition of the network, but also be effective under the fault and transient conditions of the network. In this paper, the load model and its corresponding equations have been modified. The estimation of (DFIM) parameters and the reliability of load power supply in the case of network frequency change are all included in the model. The model is simulated in Matlab/Simulink environment to verify the effectiveness of the algorithm.
