Abstract The ultra-strong solar irradiance conditions in Qatar area have natural benefits for large-scale solar photovoltaic (PV) farm deployment. However, climate issues such as soiling, extremely high temperatures and sand storms are real challenges for stable performances of solar PV farms. The integration of an energy storage system to the solar farm can be used to smooth the intermittency of the PV power generation. A 500 kW/500 kWh hybrid solar power generation/storage micro-grid system has been installed in the Solar Test Facility (STF) near Doha, Qatar. In this work, we describe the main elements that constitute the hybrid micro-grid, and the Supervisory Control and Data Acquisition (SCADA) system that has been developed to monitor the different elements of the micro-grid. We give a brief summary of the solar PV performance, analyze the impact of power fluctuations on the quality of the grid and present the data generated from the micro-grid system. We demonstrated a significant improvement of the power quality of the grid with the introduction of an energy storage system to the micro-grid.

卡塔尔气候条件下混合太阳能发电/储能微电网系统示范研究

摘要 卡塔尔地区超强太阳辐照度条件对大规模太阳能光伏发电场部署具有天然优势。然而，污染、极端高温和沙尘暴等气候问题是太阳能光伏发电场稳定性能的真正挑战。储能系统与太阳能发电场的集成可用于平滑光伏发电的间歇性。卡塔尔多哈附近的太阳能测试设施 (STF) 已安装了 500 kW/500 kWh 混合太阳能发电/存储微电网系统。在这项工作中，我们描述了构成混合微电网的主要元素，以及为监控微电网的不同元素而开发的监控和数据采集 (SCADA) 系统。我们简要总结一下太阳能光伏的性能，分析功率波动对电网质量的影响，并呈现微电网系统产生的数据。通过在微电网中引入储能系统，我们展示了电网电能质量的显着改善。
