AI Technical Summary
Existing technologies cannot reasonably allocate reserve capacity when determining the peak-shaving capacity of wind and solar power systems, making it difficult to balance the economic efficiency and security of power system operation.
Spearman's rank correlation coefficient was used to calculate the peak-shaving demand of the wind and solar system. Through correlation analysis of hourly load data and wind and solar power output data, typical reverse peak-shaving scenarios were identified, and the net load value was calculated to determine the reasonable peak-shaving capacity.
It simplifies the calculation complexity of peak-shaving capacity demand, rationally allocates reserve capacity, balances the operation economy and security of the power system, and reduces the cost of reserve capacity.
