研究目的
To analyze the impact of wind and solar energy resources integration on the load frequency control of a two-area power system, focusing on frequency deviation, maximum overshoot, and settling time under different loading conditions.
研究成果
The integration of wind and solar resources increases maximum overshoot and settling time in the power system frequency response, with wind having a greater impact than solar. An optimal loading condition exists (around half the system capacity) where these parameters are minimized. Beyond this, additional energy reserves are needed for effective load frequency control. The findings highlight the challenges of renewable integration and the necessity for enhanced control strategies.
研究不足
The study uses simulation-based analysis, which may not fully capture real-world complexities. The time series data resolution is fixed at one-fifth of a second, and nonlinearities are considered, but other factors like weather variability in renewables are not deeply explored. The system is limited to a two-area model, and results may not generalize to larger or more complex systems.
