大规模电动汽车(EV)可以聚合为高效、灵活的调频资源。然而
电动汽车聚合商(EVA)的调节潜力易受EV用户行为与调频市场价格随机性的影响,增加了电网频率控制的复杂度和风险。为此,提出一种考虑EV用户偏好和电价随机性的EVA参与调频市场的分层随机优化控制。其中,上层以调频成本为优化目标,频率偏差为概率约束,构建机会约束规划模型得到EVA和火电机组等不同调频主体的调度功率;下层采用多元高斯Copula函数构建考虑EV用户偏好和电价随机性的EVA调度指令优化分解控制模型。以15 000辆EV参与区域电网调频为例,采用实时数字仿真系统(RTDS)搭建IEEE 39节点模型,对比了3种类型EV用户偏好、荷电状态和里程价格对EVA系统调节功率、调频经济和技术性能的影响,同时所获得的结果可为含EV的电力系统调频风险决策提供技术支撑。
Large-scale electric vehicles (EVs) can be aggregated into efficient and flexible frequency regulation resources. However
the regulation potential of electric vehicle aggregators (EVAs) is susceptible to the individual behavior of EVs and the randomness of the price of the frequency regulation market
increasing the complexity and risk of power grid frequency control. To this end
a hierarchical stochastic optimal control of EVA participation in the frequency regulation market considering the EV user preference and the randomness of electricity prices is proposed. Among it
the upper layer takes the frequency regulation cost as the optimization objective and the frequency deviation as the probability constraint
and constructs the chance constrained programming model to obtain the scheduling power of various frequency regulation entities
such as EVAs and thermal power units. The lower layer adopts the multivariate Gaussian Copula function to construct an EVA dispatching instruction optimal decomposition control model considering the EV user preference and the randomness of electricity prices. Taking 15 000 EVs participating in regional power grid frequency regulation as an example
an IEEE 39-bus model is built by using a real-time digital simulation system. The influences of three types of EV user preferences
state of charge
and mileage prices on the regulated power
frequency regulation economy and technical performance of the EVA system are compared. Meanwhile
the obtained results can provide technical support for frequency regulation risk decision-making in power systems with EVs.
