摘要

目前，太阳能是解决能源危机和提高系统质量的极具潜力的替代能源。另一方面，PVGS的穿深可能会造成孤岛问题。本文提出了过欠压法和过欠频法的无检测区(NDZ)，以提高孤岛预防的准确性。除了安全问题外，本文还提出了利用遗传算法(GA)优化来提高系统可靠性的保护装置布置问题。优化还考虑了孤岛预防约束。将该方法应用于Tasine 34总线配电系统，仿真结果令人满意。

Protective device placement for reliability improvement by considering anti-islanding protection of PV generation system

At present, the solar energy is a highly potential alternative for solving the energy crisis and improving system quality. On the other hand, the penetration of PVGS may cause an islanding problem. This paper derives Non Detection Zone (NDZ) of Over/Under voltage and Over/Under frequency method in order to increase accuracy for islanding prevention. In addition to safety issue, this paper proposes the protective device placement for system reliability improvement by using Genetic Algorithm (GA) optimization. The optimization also takes account of islanding prevention as constraint. The proposed method is brought to apply with Tasine 34-bus distribution system, and the simulation results are satisfactory.
