Abstract

Expanded integration of wind energy implies technical confronts to maintain system reliability. Thus, comprehensive reliability models for wind turbines and related features are required. Composite and precise wind farms (WFs) reliability analysis includes wind turbine generator (WTG) detailed models besides wind speed (WS) probabilistic variations considering wake effects. This paper is considered as an extension to the proposed multi-state duration sampling model to asses WTG reliability integrated with a comprehensive representation for WF [1]. The paper investigates the impacts of two WTG frequency support operation algorithms on capacity factors and first hierarchical level indices. LOEE is evaluated using a novel method to emphasis the chronological coordination between load and WS attitudes. System and load points' reliability indices are estimated at moderate penetration levels of wind energy using a simplified technique. Results insure the feasibility of the composite WTG reliability model and provide reasonable indicators for WFs integration influence.

风电场容量因子和参与频率支持的影响。可靠性分析

风能的扩大整合意味着维持系统可靠性的技术挑战。因此，需要建立全面的风力发电机可靠性模型及相关特性。复合精确风电场可靠性分析除考虑尾流效应的风速概率变化外，还包括风力发电机的详细模型。本文被认为是对所提出的多状态持续时间抽样模型的扩展，该模型结合WF的综合表示来评估WTG的可靠性[1]。研究了两种WTG频率支持运行算法对容量因子和第一层次水平指标的影响。使用一种新颖的方法来评估LOEE，以强调负载和WS态度之间的时间协调。采用一种简化的方法估计了中等风力穿透水平下系统和负荷点的可靠度指标。结果保证了复合WTG可靠性模型的可行性，为WFs集成影响提供了合理的指标。
