Reactive Power Compensation for Solar Power Plants

Wednesday, December 12, 2018


Andy Leon


About the Topic

FERC Order No. 827 established clear dynamic reactive power requirements for newly interconnecting non-synchronous generators including wind turbines and solar inverters. Some transmission operators (TOs) have adopted these requirements while other TOs require plants to meet more stringent requirements. Industry practices for sizing reactive power compensation at Wind Power Plants are well established. Sizing reactive power systems for utility scale Solar Power Plants presents a new set of challenges. The real and reactive capabilities of solar inverters are significantly influenced by ambient temperature, DC link voltage, AC terminal voltage as well as inverter set points and priority modes. This presentation briefly discusses the history of reactive compensation systems and the fundamental needs of why reactive compensation is required. Various design assumptions and reactive power system options for Solar Power Plants will then be analyzed and compared.
