Incorporating Stochastic Dynamics into Real-time Simulation of Power Systems

随着可再生能源并网程度的不断提高，将其固有的随机动力学特性纳入电力系统建模中，以获得真实、准确的状态估计、稳定性评估等安全分析结果已势在必行。OPAL-RT TECHNOLOGIES是电力系统和电子实时仿真领域的全球领导者，提供从同步发电机、励磁系统到输电线路、电容器组、负载等全面的模型。然而，该公司目前的模型并没有纳入可再生能源发电机的随机特性。该项目旨在将电力系统组件的内在不确定性纳入公司的实时模拟器中。该项目的成果将为现有库增加更真实和准确的风力涡轮机、光伏和负载模型，从而为现代电网提供更准确的安全分析。

As the integration of renewable energy sources continues increasing, it is imperative to incorporate theirintrinsic stochastic dynamics in power system modelling to achieve realistic and accurate security analysisresults such as state estimations, stability assessments, etc. OPAL-RT TECHNOLOGIES is a world leader inpower system and electronics real-time simulation offering comprehensive models from synchronousgenerators, excitation systems, to transmission lines, capacitor banks, loads, etc. However, the current modelsof the company have not incorporated the stochastic characteristics of the renewable generators. The proposedproject aims to incorporate the intrinsic uncertainties of power system components into the real-time simulatorof the company. The outcomes of the project will add more realistic and accurate models of wind turbines,photovoltaic and loads to the existing library leading to more accurate security analysis for modern powergrids.
