AI Technical Summary
The existing technology is difficult to quickly and effectively obtain and control the minimum power generation cost increment λ in the power system, especially when the total load of the system changes, resulting in the required λ not meeting the actual situation.
The minimum power generation cost increment acquisition method based on the decentralized relaxation factor power flow model is adopted. By establishing the decentralized relaxation factor power flow calculation model and the minimum power generation cost increment calculation model, the Lagrangian function and the dual interior point method are used to solve the control system λ The number of iterations is small and fast.
It makes the required λ more consistent with the actual situation, maintains efficient convergence and robustness, the system λ is controllable, the number of iterations is small, and the acquisition speed is faster.
