本文提出了一种长期影响评估算法，用于评估分布式发电有意孤岛配电系统中先进的低频减载方案。该算法基于离散-连续相结合的仿真模型，验证了方案对系统平均中断频率指标、系统平均中断持续时间指标和未供电能量等可靠性指标的影响。此外，为了说明评估的适用性，我们还实现了一种基于多项式神经网络的超前减载方法来支持DG孤岛。模拟结果强调了使用UFLS支持使用巴西南部实际网络的DG孤岛的长期效果。
This paper presents a long-term impact evaluation algorithm to assess advanced under frequency load shedding (UFLS) schemes on distribution systems with intentional islanding of distributed generation (DG). The algorithm is based on a combined discrete-continuous simulation model which is utilized to verify the effect of the schemes on reliability indices such as the system average interruption frequency index, system average interruption duration index, and energy not supplied. Moreover, a polynomial neural network-based approach to advanced load shedding is implemented to support DG islanding in order to illustrate the applicability of the evaluation. Simulation results highlight the long-term effect of employing UFLS to support intentional islanding of DG using an actual network from the South of Brazil.
