摘　　要：蓄热电采暖因其用电时段可调、运行经济灵活,已经成为西北地区冬季取暖期重要的灵活性调节资源。合理地规划蓄热电采暖容量可以有效提高风电消纳水平,提升系统的运行经济性。为此,该文提出一种考虑热舒适度弹性和提升风电消纳的蓄热电采暖双层优化配置方法。通过引入热感觉平均标度预测(predicted mean vote,PMV)指标来量化用户的热舒适度,根据热舒适度弹性的限定范围确立热平衡区间约束。在分别分析系统风电消纳以及热舒适度弹性对蓄热电采暖容量配置的影响的基础上,建立兼顾风电消纳和热舒适度弹性的蓄热电采暖双层优化配置模型。上层以风电供热系统年化总成本最小为目标,下层以系统典型日运行成本最小为目标,通过上下层迭代求解蓄热电采暖最优容量配置以及系统运行方案。最后,基于实际算例验证了所提的蓄热电采暖配置方法可在保证供暖舒适度的基础上提升风电消纳水平和系统整体经济性。Thermal storage electric heating has become an important flexible regulating resource for the winter heating period in Northwest China because of its adjustable power consumption period and economic and flexible operation.Reasonable thermal storage electric heating capacity planning can improve wind power consumption and enhance the system's operating economy.Therefore,this paper proposes a dual-layer optimization configuration method for thermal storage electric heating that considers thermal comfort elasticity and enhances wind power consumption.By introducing the predicted mean vote(PMV)index to quantify user thermal comfort,the thermal balance interval constraint is established based on the limited range of thermal comfort elasticity.Based on the analysis of the impact of system wind power consumption and thermal comfort elasticity on the configuration of thermal storage electric heating capacity,a dual layer optimization configuration model for thermal storage electric heating that considers both wind power consumption and thermal comfort elasticity is established.The upper layer uses wind power consumption and thermal comfort elasticity as the basis,and the upper layer establishes a thermal balance interval constraint.The goal is to minimize the annual total cost of the heating system,and the goal is to minimize the typical daily operating cost of the system at the lower level.The optimal capacity configuration and system operation plan for thermal storage electric heating is iteratively solved at the upper and lower levels.Finally,based on actual examples,the proposed thermal storage electric heating configuration method is verified to improve wind power consumption and overall system economy while ensuring heating comfort.
