论文摘要
{用于求解分配网络（DN）电压和热凝集的可算力且灵活的资源激活框架用于量化有关建模低压网络的三个重要方面。}此框架在没有此类框架的情况下利用网络状态在没有此类灵活或简洁的资源的情况下，作为计算灵活性激活信号的输入（FAS）。 FAS具有一些与最佳功率流二元组的相似之处（与功率平衡约束相关联}。 FAS由于设计下垂，在任何网络限制违规行为之前，{激励纠正灵活性激活}。 {非线性资源调度最佳功率流（RDOPF）利用FAS激活灵活和可限制的资源。解决大型系统的OPF问题是计算密集型的，并且在文献中经常应用二阶锥体（SOC）放松。} {} {first，}我们强调了SOC放松RDOPF的多目标性质。帕累托前调谐机制（提出了选择损失惩罚因素的建议}，同时减少了SOC宽松的RDOPF的最佳差距。 {其次，我们}提出了一种评估DN的时间和位置灵活性需求评估的方法，DSO可以将其用于灵活性计划{在操作时间表和灵活性市场中的采购}。 {最后，我们}量化了具有不同负载功率因子的DN的反应能力灵活性的影响。 {数值模拟表明，具有0.8汇总负载功率因子的测试馈线的活性功率灵活性的存在可将主动功率灵活性需求降低50 \％。}
{A curtailable and flexible resource activation framework for solving distribution network (DN) voltage and thermal congestions is used to quantify three important aspects with respect to modelling low voltage networks.} This framework utilizes the network states in the absence of such flexible or curtailable resources as the input for calculating flexibility activation signal (FAS). The FAS has some similarities with optimal power flow duals {associated with power balance constraint}. FAS due to drooping design, {incentivize corrective flexibility activation} prior to any network limit violations. {The nonlinear resource dispatch optimal power flow (RDOPF) utilizes FAS for the activation of flexible and curtailable resources. Solving the OPF problem for a large system is computationally intensive, and second-order cone (SOC) relaxation is often applied in the literature.} {First,} we highlight the multi-objective nature of SOC relaxed RDOPF. A Pareto front tuning mechanism {is proposed for choosing loss penalty factor} while reducing the optimality gap of the SOC relaxed RDOPF. {Secondly, we} present a methodology for evaluating temporal and locational flexibility needs assessment of a DN, which DSO's can utilize for flexibility planning {in operational timescales and procurement in the flexibility market}. {Lastly, we} quantify the impact of reactive power flexibility for a DN with varying load power factors. {Numerical simulations indicate that the presence of reactive flexibility reduces the active power flexibility needs by 50\% for the test feeder with 0.8 aggregated load power factor.}
