Abstract
To investigate the economic impact of wind power output volatility on the operation of power systems, this study constructs a low-carbon dispatch model for power systems that takes into account the volatility of wind power output. By setting different levels of volatility to alter the wind power output, the study ultimately examines the influence of wind power volatility on the overall cost and carbon emission cost of the system. The experimental results indicate that as wind power volatility increases, the on-off states of conventional power generation units change. This not only affects the secure and stable operation of the power system but also leads to increased start-up and shutdown costs for the units, along with an increase in carbon emission costs. Consequently, the total system cost rises, impacting the economic efficiency of system operation. Therefore, in future research, measures should be taken to reduce the numerical value of wind power volatility in order to reduce overall costs and improve the economic efficiency of system operation.
