电力系统规划工程师目前基于代表典型系统操作点的几个快照（也称为基本潮流情况）执行规划研究。然而，这还不足以充分理解和评估当前和未来电网的运行影响，特别是在高度不确定性和极端事件中。必须考虑时间序列分析。我们开发了一个程序，使用生产成本模型（PCM）模拟数据的风力，光伏发电和负载水平，以产生时间顺序，每小时的潮流情况。由于PCM使用无损、线性、直流潮流解决方案进行仿真，因此交流潮流必须收敛，以便进行可靠性规划研究。本文介绍了一个程序来处理损失和无功功率规划的大型，互联系统。以西部电力协调理事会（WECC）2028锚数据集（ADS）作为PCM和WECC 2028高夏季潮流情况（22，000母线系统）作为参考的示例来说明该过程。该过程可应用于具有任何电网拓扑的多个AC和DC电网的系统。
Power system planning engineers currently perform planning studies based on a few snapshots representing typical system operating points, also known as base power flow cases. However, that is not enough to fully understand and evaluate operational impacts of the current and future grid, especially in high uncertainty and extreme events. Time-series analysis must be considered. We developed a procedure for using production cost model (PCM) simulation data for wind, photovoltaic, and load levels to generate chronological, hourly power flow cases. Because the PCM uses a lossless, linear, DC power-flow solution for simulations, AC power flow must be converged to enable reliability planning studies. This paper describes a procedure to handle losses and reactive power planning for large, interconnected systems. The procedure is illustrated with an example using the Western Electricity Coordinating Council (WECC) 2028 Anchor Data Set (ADS) as a PCM and the WECC 2028 High Summer Power Flow case (22,000 bus system) as references. This procedure can be applied to systems with multiple AC and DC grids of any grid topology.
