摘要
基于灵敏度分析与神经网络,提出了一种互联电力系统联络线功率调整的新方法。通过运用BPA软件获取适当的神经网络模型数据样本,不同电厂相对于联络线的灵敏度系数可运用BP神经网络算法进行求导计算。搭建了新的联络线功率调整分析模型,并虑及了与联络线弱联或非联电厂之间的发电功率协调问题。采用含有不同区域电厂的IEEE-30节点系统对新建模型进行仿真,并与采用其他文献研究方法的仿真结果进行比较,验证了该方法的有效性和实用性。
A new method is presented based on sensitivity analysis and neural network to adjust power of interconnected power system tie-line.Suitable data sample of neural network model can be acquired by BPA software,sensitivity coefficients of different power plants relative to the tie-line can be calculated through BP neural network algorithm.A new tie-line power adjustment analysis model has been established with the consideration of power coordination in power plant which has weak or no link with tie line.IEEE-30 bus system including power plants in different areas is adopted to simulate the new model.With comparison to other simulation results,the effectiveness and practicality of the proposed method is testified.
