This paper presents the details of exhaustive investigations on a typical Saudi distribution network showing the effectiveness of various control techniques to mitigate the voltage rise issues due to high penetration of solar photovoltaic (PV) systems. One of the major goals of Saudi Arabia future economic plans is to expand on renewable energy installations throughout the Kingdom. It is planned to generate 9.5 GW of electric power from renewable energy sources by 2023. Further, energy regulators in the Kingdom have announced policies and regulations govern the integration of small- and large-scale solar PV. However, distributed solar PV systems come with technical challenges, especially during high level of integration including grid stability, voltage rise, flickering, frequency fluctuation, and protection and coordination schemes. One issue is that the voltage profile is expected to change and rise to unacceptable level, especially with high solar PV penetration. Various voltage rise mitigation techniques investigated include active power curtailment, reactive power injection, and also a hybrid combination of these two methods. The paper reports the results of both steady-state and dynamic analyses of the Saudi distribution network at various load levels. The investigations reveal that the hybrid approach is more effective in the voltage rise mitigation.

缓解因沙特配电网太阳能光伏渗透率高而导致的电压上升

本文详细介绍了对典型沙特配电网络的详尽调查，展示了各种控制技术在缓解太阳能光伏 (PV) 系统高渗透率引起的电压上升问题方面的有效性。沙特阿拉伯未来经济计划的主要目标之一是在整个王国扩展可再生能源装置。计划到 2023 年从可再生能源中产生 9.5 吉瓦的电力。此外，王国的能源监管机构已经宣布了管理小型和大型太阳能光伏发电整合的政策和法规。然而，分布式太阳能光伏系统面临着技术挑战，特别是在电网稳定性、电压上升、闪烁、频率波动以及保护和协调方案等高度集成的情况下。一个问题是电压分布预计会改变并上升到不可接受的水平，尤其是在太阳能光伏渗透率高的情况下。研究的各种电压上升缓解技术包括有功功率削减、无功功率注入以及这两种方法的混合组合。该论文报告了沙特配电网络在不同负载水平下的稳态和动态分析结果。研究表明，混合方法在缓解电压上升方面更有效。该论文报告了沙特配电网络在不同负载水平下的稳态和动态分析结果。研究表明，混合方法在缓解电压上升方面更有效。该论文报告了沙特配电网络在不同负载水平下的稳态和动态分析结果。研究表明，混合方法在缓解电压上升方面更有效。
