大量分布式发电机组接入导致电网强度弱化
进而造成光伏集群输出电流谐波谐振,威胁系统安全稳定运行。为此,考虑谐波谐振约束,基于系统源网阻抗聚合模型及稳定性指标,构建了新能源并网功率一定情况下系统稳定裕度最优的目标函数,将牛顿数值迭代融入拉格朗日条件极值求解过程之中,实现阻抗灵敏度趋于一致的快速调节。面向固定功率及并网功率最大分配应用场景,提出了基于牛顿迭代型灵敏度协同的新能源并网功率优化分配方法,并与常规集群功率分配方法及同类优化分配方法进行对比,所提功率优化分配方法求解效率高、算力需求较小。最后,基于硬件在环实时数字仿真平台搭建IEEE 33节点算例,对所提方法进行了验证。
The integration of a large number of distributed power generation units results in weakening power grid strength
which in turn causes harmonic resonance of output current of photovoltaic cluster
threatening the safe and stable operation of power system. Therefore
considering the constraint of harmonic resonance
based on the source and grid impedance aggregation model and stability index of the system
the objective function of the optimal stability margin for the system under a certain grid-connected power of renewable energy is constructed. The Newton numerical iteration is integrated into the solving process of Lagrange condition extremum to achieve rapid adjustment of impedance sensitivity towards consistency. Aiming at the application scenarios of constant power and the allocation of maximum grid-connected power
an optimal allocation method of grid-connected power based on Newton iterative sensitivity collaboration is proposed. Compared with conventional cluster power allocation methods and similar optimal allocation methods
the proposed optimal power allocation method has high solving efficiency and low computing power requirements. Finally
an IEEE 33-bus case is built on the real-time hardware-in-the-loop digital simulation system to validate the proposed method.
