  • 摘要: 增加可再生能源在电网中的占比, 使能源结构更合理, 是加快能源转型实现低碳可持续发展的有效途径. 电网中占主导地位的火电, 辅助消纳可再生能源的能力, 对提高可再生能源在电网中的占比起到重要作用. 为了提高火电机组辅助可再生能源的消纳能力, 本文根据当前系统控制方案, 分析了影响机组灵活性与调峰深度的因素, 包括机炉协调、局部反馈策略下的锅炉控制、系统稳态工作点的规划等. 基于补偿方案的协调策略限制了机组对具有随机性和间歇性的可再生能源的补偿能力; 局部反馈策略下的锅炉控制只是实现了等效热效应的反馈; 非额定工况下的稳态工作点关系到辅助可再生能源消纳的能耗和排放指标. 根据以上分析分别给出了进一步的研究内容.
