Abstract This paper discusses the impact of the sub-hourly unit commitment problem on power system dynamics. Such an impact is evaluated by means of a co-simulation platform that embeds a sub-hourly stochastic mixed-integer linear programming security constrained unit commitment (sSCUC) into a time domain simulator, as well as includes a rolling planning horizon that accounts for forecast updates. The paper considers different sub-hourly sSCUC resolutions (i.e., 5 and 15 min) and different wind penetration levels (i.e., 25 and 50%). The focus is on the transient response of the system and on frequency variations following different sSCUC strategies, and different sSCUC wind power uncertainty and volatility. The case study consists of a comprehensive set of Monte Carlo simulations based on the 39-bus system.

亚小时机组承诺对电力系统动态的影响分析

摘要 本文讨论了亚小时单位承诺问题对电力系统动力学的影响。这种影响是通过一个联合仿真平台来评估的,该平台将亚小时随机混合整数线性规划安全约束单元承诺 (sSCUC) 嵌入到时域模拟器中,并包括一个滚动规划范围来考虑预测更新。该论文考虑了不同的亚小时 sSCUC 分辨率(即 5 和 15 分钟)和不同的风穿透水平(即 25 和 50%)。重点是系统的瞬态响应和不同 sSCUC 策略后的频率变化,以及不同的 sSCUC 风电不确定性和波动性。案例研究包括一套基于 39 总线系统的综合蒙特卡罗模拟。
