分布式光伏、储能及电动汽车等灵活性资源广泛接入低压台区，对台区可开放容量评估提出了新挑战。为此，提出了一种计及灵活性资源调控的低压台区可开放容量弹性区间评估方法。首先，建立了低压台区灵活性资源的数学模型，分析其可调节潜力。其次，基于灵活性资源优化调度并考虑不确定性因素，构建了信息间隙决策理论（information gap decision theory，IGDT）的低压台区可开放容量弹性区间评估模型。最后，通过不同台区算例仿真，从电源接入与负荷接入两个维度分析了多种灵活性资源组合下的可开放容量弹性区间，验证了模型的有效性。

The widespread integration of flexible resources such as distributed photovoltaics, energy storage, and electric vehicles into low-voltage substations poses new challenges to the assessment of open capacity in substations. Therefore, an open capacity elastic interval evaluation method for low-voltage substation considering flexible resource regulation is proposed. Firstly, a mathematical model is established for the flexibility resources of the low-voltage substation and its adjustable potential is analyzed. Secondly, based on flexible resource optimal dispatch and considering uncertainty factors, an open capacity elastic interval evaluation model for low-voltage substation is constructed using information gap decision theory (IGDT). Finally, through simulations of different station areas, the open capacity elastic interval under various flexible resource combinations is analyzed from the perspectives of power supply and load access, and the effectiveness of the model is verified.
