Optimized Power Distribution Technology for Fast Frequency Response in Photovoltaic Power Stations

The fast frequency response (FFR) function in renewable energy source (RES)-based power stations has proved to be able improve the stability of systems with high RES penetration significantly. However, most current FFR functions photovoltaic (PV) typically show deviations and unnecessary loss issues that are caused by inadequate station distribution strategies. This is particularly important cases where must increased when system shows a downward disturbance. paper proposes new strategy for PV studies related strategies, structures, calculation algorithms, execution effect, active regulation technology. proposed approach uses proportional based on an evaluation real-time potential maximum capability values subarrays or generation regions, which evaluated using few reference inverters located every subarray region. Real-site deployments tests have been completed verify effectiveness this strategy, solution demonstrated strong performance wider application scenarios.
