Simulation Technology of Sequential Production of New Energy Power System Based on Linear Power Flow

随着电力系统中新能源占比的不断攀升,为了准确评估地区电网新能源消纳能力,提出了基于线性潮流的电力系统时序生产模拟技术,在传统时序生产模拟模型基础上,进一步考虑线性化后的输电网潮流约束,同时采取电力时序生产模拟与线性潮流计算的迭代关联法对模型进行求解。最后以改进的IEEE 30节点系统作为算例,进行新能源消纳分析,结果验证了模型的可行性和有效性。

With the increasing proportion of new energy in the power system,in order to accurately evaluate the new energy consumption capacity of the regional power grid,a simulation technology of power time series production based on linear power flow is proposed.On the basis of the traditional time series production simulation model,the linearized power flow constraints of the transmission network are further considered,and the model is solved by the iterative correlation method of power time series production simulation and linear power flow calculation.Finally,taking the improved IEEE 30-node system as an example,the new energy consumption analysis is carried out,and the results verify the feasibility and effectiveness of the model.
