As modern grids shift towards renewable energy (RE), new challenges arise with higher penetration of inverter-based distributed energy resources (DER). The variability and intermittency of RE also pose significant challenges for grid operation. Therefore, DER standards are updated/revised with new grid support functions to ensure proper grid operation with higher penetration of renewable energy. This paper presents an assessment of the frequency-droop function from the recently revised IEEE 1547-2018 standard. The function is assessed using high-resolution solar photovoltaic (PV) system production data from commercial PV inverters of a 5 MW solar farm. Several issues with the current droop function implementation is discussed. In addition, PV energy curtailment with different settings of the droop function is also assessed. The results are presented using the datasets of five days with different levels of solar variability. The daily energy curtailment can be as high as 4.1% and 13.2% with IEEE 1547 and CSA C22.3 No. 9 standards respectively. |
