摘要:
由于风能具有随机性、间歇性与波动性等特点，致使当大规模风电场接入电力系统后，会给系统造成不可忽视的负面影响，从而给电网的安全稳定运行带来风险。本文基于运行风险评估框架理论体系，建立了相应的运行风险评估指标体系，分别从局部级和系统级两个层面反映系统的短期运行风险水平。最后，基于IEEE-RTS79验证上述所建评估框架理论体系的正确性。Due to the randomness, intermittent and fluctuation characteristics of wind energy, the negative effects brought by large-scale wind farms when they are connected to the power system cannot be neglected. Large scale wind farm connected to power grid will bring operational risk to the grid. Based on the theoretical framework of operational risk assessment, this paper established the corresponding operational risk assessment index system, which reflects the system’s short-term level of the operational risk from the local and system level respectively. At last, the accuracy of the established assessment index system is proved based on the IEEE-RTS79 system.
