The integration of wind power storage systems offers a viable means to alleviate the adverse impacts correlated to the penetration of wind power into the electricity supply. Energy storage systems offer a diverse range of security measures for energy systems, encompassing frequency detection, peak control, and energy efficiency enhancement .
When considering the integration of wind and solar power, increasing the installed capacity of renewable energy while maintaining a certain wind-solar ratio can effectively match the power generation with the user load within a specific range. In engineering design, it is essential to address the issue of ensuring supply from 16:00 to 22:00.
Correspondingly, the wind power output load ratio spans from 68% to 72%, aligning harmoniously with the daily wind power load ratio of 71%. These findings substantiate the equilibrium maintained by our distributed wind power devices in terms of load and output power, thus ensuring a secure and stable power supply.
The wind-to-solar capacity ratio for the maximum installable capacity of the system is around 1.25:1. This indicates that setting the loss of load rate at 3 % during the design phase allows the complementary characteristics of wind and solar power to be fully utilized, making it more suitable for dealing with fluctuations in user load.
At this ratio, the maximum wind-solar integration capacity reaches 3938.63 MW, with a curtailment rate of wind and solar power kept below 3 % and a loss of load probability maintained at 0 %. Furthermore, under varying loss of load probabilities, the total integration capacity of wind and solar power increases significantly.
To sustain a stable and cost-effective transformation, large wind integration needs advanced control and energy storage technology. In recent years, hybrid energy sources with components including wind, solar, and energy storage systems have gained popularity.
