The rising demand for electrical energy and decreasing capital cost of photovoltaic (PV) panels led to rapid growth in large‐scale solar PV system penetration in many countries, including Turkey. This article focused on a cost‐effective and efficient decentralized voltage and reactive power (Volt/Var) control approach in distribution networks at the presence of high penetrated solar PV farms utilized as static synchronous compensator (PV‐STATCOM) which has been recently proposed. A proper coordinated control of large number of PV‐STATCOMs suggested to achieve optimal reactive power scheduling for the next day ahead. This article introduced implementation of a modified Lévy flight‐based firefly algorithm (MLFA) to multi‐objective Volt/Var optimization problem, which was employed for minimizing active power loss and cost of energy. The validity and applicability of the proposed method were confirmed by implementing it on a real megavolt (MV) Turkish distribution network for various loading conditions. Simulation results show that the results of MLFA to this problem outperform those of other methods. Furthermore, application of the proposed method offers opportunity to distribution system operators for a large amount of cost savings and loss reduction without compromising voltage regulatory limits.

计入STATCOM的高穿透光伏太阳能场无功贡献的日常伏特/瓦尔计划的技术经济管理：土耳其伊斯坦布尔的案例研究

对电能的需求不断增加以及光伏（PV）面板的资本成本不断下降，导致包括土耳其在内的许多国家的大规模太阳能光伏系统普及率迅速增长。本文重点介绍了在最近提出的高穿透率太阳能光伏发电场用作静态同步补偿器（PV-STATCOM）的情况下，配电网络中具有成本效益的高效分散式电压和无功功率（Volt / Var）控制方法。建议对大量PV-STATCOM进行适当的协调控制，以在第二天实现最佳无功功率调度。本文介绍了针对多目标Volt / Var优化问题的改进的基于Lévy飞行的萤火虫算法（MLFA）的实现，该问题用于最小化有功功率损耗和能源成本。通过在各种负载条件下的实际兆伏（MV）土耳其配电网络上实施该方法，证实了该方法的有效性和适用性。仿真结果表明，针对该问题的MLFA结果优于其他方法。此外，所提出方法的应用为配电系统运营商提供了在不损害电压调节极限的情况下大量节省成本和减少损失的机会。
