摘要(Abstract)：

为实现电力低碳化、促进可再生能源并网消纳,需要考虑大规模波动性电源的不确定性对电网运行调度的影响。在分析碳捕集机组及光热电站工作原理的基础上,引入模糊理论,将风电和负荷用模糊参数表示,使确定性的系统约束变为基于可信性理论的模糊机会约束,构建了考虑源荷不确定性的风电-光热-碳捕集虚拟电厂协调优化调度模型。通过优化各机组出力,在提高风电并网消纳量的同时降低碳排放量,该调度模型综合考虑碳捕集机组发电成本、风电和光热并网消纳的运行维护成本、碳交易市场收益以及电网安全运行约束等因素,并应用梯形隶属度参数的清晰等价类,将机会约束清晰化,以对模糊机会约束进行求解。算例基于西北某省风电、负荷实测数据,通过CPLEX优化软件求解模型,仿真结果验证了所提调度模型可有效促进风电消纳、实现电力低碳化。
