New-energy reserve capacity can aid primary frequency recovery

What the study found: The study found that giving new energy sources an appropriate reserve for primary frequency regulation can help system frequency recover quickly. It also reports that reserve capacity, response speed, and regulation rate together shape the frequency trajectory after a disturbance.
Why the authors say this matters: The authors say the work matters because power systems with a high share of new energy need rapid frequency response, and the findings indicate that reserve configuration should consider both system frequency response performance and new energy consumption demand.
What the researchers tested: The researchers compared the primary frequency regulation control performance of wind power generation, photovoltaic power generation, and thermal power generation. They analyzed how frequency distribution, regulation rate, frequency regulation capacity, and frequency deviation affect primary frequency regulation, and proposed an optimization method for reserve configuration using simulation on a simplified actual power system.
What worked and what didn't: The simulation results showed that an appropriate reserve from new energy helped the system frequency recover quickly. The abstract does not report which specific reserve settings worked best beyond that general conclusion.
What to keep in mind: The abstract refers to a simplified actual power system, so the results are based on simulation rather than a full real-world deployment. Other limitations are not described in the available summary.
