Source-Grid-Load-Storage Coodination-considered Optimized Safety-constrained Unit Combination
Achieving full potentialof various kinds of power sources is of significance for coping with the uncertainty brought by high-proportion integration of wind and photovoltaic generations.In view of this,the present work made an at-tempt at establishing a multi-flexible-source-entailed security-constrained unit combination model based on the conventional flexible sources,such as thermal power units with rapid rise/fall spinning reserve,and transmission line switching.The model integrates demand response,transmission line switching,and public energy storage into one com-bined scheme.It coordinates and optimizes these flexible sources on the sides of source,grid,load,or storage,thereby fa-cilitates coping with the uncertainties resulted from wind and photovoltaic generations and accidental faults of system com-ponents.Aiming at this large and complex computing problem,a new accelerated decomposition technology was proposed to improve the efficiency of model solving and reduce the number of iterations and CPU computing time.
