Abstract

Wind power is growing at a very fast pace as an alternative generating resource. As the ratio of wind power over total system capacity increases, the impact of wind on various system aspects becomes significant. This paper presents a methodology to study the future impact of wind on BPA power system load following and regulation requirements. Existing methodologies for similar analysis include dispatch model simulation and standard deviation evaluation on load and wind data. The methodology proposed in this paper uses historical data and stochastic processes to simulate the load balancing processes in the BPA power system. It mimics the actual power system operations therefore the results are close to reality yet the study based on this methodology is convenient to perform. The capacity, ramp rate and ramp duration characteristics are extracted from the simulation results. System load following and regulation capacity requirements are calculated accordingly. The ramp rate and ramp duration data obtained from the analysis can be used to evaluate generation fleet ramp requirement and regulating unitspsila energy requirement, respectively.

未来风对双酚a电力系统负荷的影响及调控要求

风能作为一种可替代的发电资源正在以非常快的速度发展。随着风电占系统总容量的比例增加，风对系统各方面的影响变得显著。本文提出了一种研究未来风对双酚a电力系统负荷跟随和调节要求影响的方法。现有的类似分析方法包括调度模型仿真和负荷与风力数据的标准差评估。本文提出的方法是利用历史数据和随机过程来模拟双酚a电力系统的负载均衡过程。该方法模拟了电力系统的实际运行情况，结果与实际情况较为接近，且便于进行研究。从仿真结果中提取了容量、斜坡速率和斜坡持续时间特征。据此计算系统负荷跟随和调节能力需求。通过分析得到的匝道率和匝道持续时间数据可分别用于评估发电机组的匝道需求和调节机组的能源需求。
