Voltage instability is a major problem facing power utility companies due to a lack of maintenance and financial support to maintain the existing power system networks (PSN). Lack of maintenance occurs when PS fails to replace the aging equipment and services and upgrades existing networks. Also, the lack of financial support occurs when there is insufficient financial capital to carry out the above maintenance activities, which has incurred greater power loss in the systems. There is a need to eliminate the loss incurred in the system to avoid voltage collapse. The best way to increase the lifespan of a PSN and improve voltage stability is the optimum allocation of distributed generation (DG). The most common DG are solar photovoltaic (PV) and wind turbines. This review discusses the economic, environmental, and technical benefits of non-traditional DG technologies over a traditional system. However, this work reviewed different DG technologies that can be incorporated into PSN for better loss reduction. Detailed descriptions of energy loss, power loss, and multi-objectives for optimal DG planning were also discussed, along with comprehensive methods used in the sizing and placement of DG for voltage profile improvement (VPI). The findings recommend that the hybrid meta-heuristic algorithm be used for DG placement has it significantly improves voltage profile and lowers power loss. The present study concluded that with proper DG placement, the advantage of DG can be maximally accomplished, the voltage profile is improved, and losses are minimized.
由于缺乏维护和资金支持来维持现有的电力系统网络（PSN），电压不稳定是电力公司面临的一个主要问题。当电力系统未能更换老化设备和服务以及升级现有网络时，就会出现维护不足的情况。此外，当没有足够的资金来开展上述维护活动时，就会出现资金支持不足的问题，这会导致系统中更大的功率损耗。有必要消除系统中产生的损耗，以避免电压崩溃。增加电力系统网络寿命并提高电压稳定性的最佳方法是优化分布式发电（DG）的配置。最常见的分布式发电是太阳能光伏（PV）和风力涡轮机。本综述讨论了非传统分布式发电技术相对于传统系统在经济、环境和技术方面的优势。然而，这项工作回顾了不同的分布式发电技术，这些技术可以纳入电力系统网络以更好地降低损耗。还讨论了能量损耗、功率损耗以及分布式发电优化规划的多目标的详细描述，以及用于确定分布式发电的规模和位置以改善电压分布（VPI）的综合方法。研究结果建议使用混合元启发式算法进行分布式发电的布局，因为它能显著改善电压分布并降低功率损耗。本研究得出结论，通过合理布局分布式发电，可以最大程度地实现其优势，改善电压分布并将损耗降至最低。
