本研究依赖于一种实验方法，利用真实的数据从多个光伏（PV）位于美国东北部地区的网站，检查不同的逆变器无功和有功功率设置如何影响电网电压调节和逆变器的预期寿命。这些电压调节方案对操作者来说是有代价的。分析了来自不同太阳能发电站的数据，这些发电站的逆变器在不同的无功和有功功率设置下运行，以比较运营权衡。这些权衡的范围从生产损失到缩短逆变器的使用寿命。分析电压与无功功率图以显示生产损失，而热分析用于与逆变器预期寿命相关。
This study relies on an experimental approach, utilising real data from multiple photovoltaic (PV) sites located in the US Northeaster region, to inspect how different inverter reactive and active power settings impact gird voltage regulation and inverter life expectancy. These voltage regulation schemes come at a cost for the operator. Data from different solar sites with inverters running at different reactive and active power settings were analysed to compare operational trade‐offs. These trade‐offs range from production losses to shortening the lifetime of the inverters. Voltage versus reactive power plots were analysed to show production losses, while the thermal analysis was used to correlate with the inverter life expectancy.
