考虑运行风险的含储能综合能源系统优化调度
摘要：为解决综合能源系统（integrated energy system，IES）中供需双侧不确定因素对运行调度带来的风险问题，提出了一种考虑运行风险的含储能IES优化调度模型。在目标函数中，用设备调整费用、失负荷惩罚费用和弃风弃光惩罚费用来量化系统运行风险。在约束条件中，区分了电能和热能的时间尺度差异，并计及储能的时间耦合性，建立了储能多时段耦合约束。然后提出了一种基于Benders分解的算法进行求解。最后通过算例分析了置信水平、储能功率及容量对IES运行费用及运行风险的影响。
Abstract:In order to solve the risk problem brought by uncertainties of supply and demand in integrated energy system (IES), an optimal dispatch model of IES with energy storage considering operational risk was proposed. In the objective function, the cost of equipment adjustment, penalty for loss of load and penalty for curtailment of wind and solar power was used to quantify the operational risk of the IES. In the constraints, the time-scale differences between electric energy and thermal energy were distinguished, and the multi-period coupling constraints of energy storage were established considering the time coupling of energy storage. Then an algorithm based on Benders decomposition was proposed to solve the problem. Finally, an example was given to analyze the influence of confidence level, energy storage power and capacity on IES operation cost and operational risk.
