Renewable energy development (RED) impacts power supply reliability (PSR) in China. While RED
Area of Science:
- Energy Systems Engineering
- Environmental Economics
- Power System Reliability
Background:
- The global shift towards low-carbon energy systems necessitates the integration of renewable energy sources.
- Renewable energy development (RED) introduces complexities and uncertainties into power system reliability (PSR).
- Understanding the nuanced relationship between RED and PSR is crucial for sustainable energy transitions.
Purpose of the Study:
- To investigate the impact of renewable energy development on power supply reliability in China.
- To analyze regional disparities in the effects of RED on PSR.
- To identify critical factors influencing the relationship between RED and PSR.
Main Methods:
- Utilized provincial data from China spanning 2012-2020.
- Employed panel data analysis and a panel threshold model.
- Assessed the influence of renewable energy development on power supply reliability.
Main Results:
- The negative impact of RED on PSR has diminished over time.
- Rational RED strategies can enhance PSR.
- Energy-exporting regions face greater PSR risks from RED compared to energy-importing regions.
- Stable coal prices and manageable natural disasters facilitate RED's positive impact on PSR.
- Unstable conditions exacerbate PSR issues with high renewable energy penetration.
Conclusions:
- The relationship between RED and PSR is context-dependent and influenced by external factors.
- Policy interventions are needed to mitigate risks and optimize RED for improved PSR.
- Developing a new power system requires careful consideration of RED's impact on reliability.
