摘要 间歇性电源的并入给电网带来了显著的经济效益和减排效益,同时其出力的不确定性给电网动态经济调度带来新问题。针对上述问题,建立考虑节能减排的含有间歇性电源多目标模糊机会约束动态经济调度模型。首先,分析预测误差在不同功率预测值区间的模糊特性,并拟合出分布参数,进而获得间歇式电源出力和负荷的模糊隶属度函数。其次,基于模糊集理论对不同的系统约束形成不同测度的模糊机会约束,建立考虑运行费用、SO2排放量和CO2排放量的多目标模糊机会约束动态经济调度模型。在模型求解上,通过定义目标隶属度函数和凸模糊决策将多目标问题转换为单目标问题,采用清晰等价类将机会约束清晰化,并提出改进的萤火虫算法对模型进行求解。算例分析验证所提模型和算法的可行性和有效性。

Abstract:Intermittent powers connected to the grid bring about significant economic and emission reduction benefits.But their uncertainty outputs cause new problems to the grid dynamic economic dispatch.In order to solve this problem,a multi-objective fuzzy chance constrained dynamic economic dispatch model with intermittent powers considering energy saving and emission reduction is proposed.Firstly the fuzzy characteristics of the prediction errors in different power prediction regions are analyzed and then the distribution parameters are fitted.Thus the fuzzy membership functions of the intermittent powers’ output and the load are obtained.Secondly,different fuzzy chance constraints with different measures for different system constraints are considered with the fuzzy theory.A multi-objective fuzzy chance constrained dynamic economic dispatch model considering operating expenses and CO2 and SO2 emissions is then established.To solve the model,the multiple objectives are transformed into a single objective through defining the objective membership function and the product convex fuzzy decision,the chance constraints are turned into their clear equivalent forms using clear equivalent,and an improved firefly optimization algorithm is used.The feasibility and the effectiveness of the proposed model and algorithm are verified by the analysis of the case.
