AI Technical Summary
In existing virtual power plant power regulation, the fixed parameters of the ADMM algorithm make it difficult to adapt to the physical response lag of components and communication delays, resulting in power regulation overshoot or oscillation. This makes it difficult to meet the real-time compensation requirements at the second or even millisecond level, affecting the stability and accuracy of the power system.
A response deviation inertia mapping index and a deviation accumulation dynamic correlation index are constructed. By dynamically adjusting the penalty parameter of the distributed optimization objective function through sensitivity adaptive feedback gain, closed-loop feedback control is achieved, thereby improving the algorithm's adaptability and convergence speed.
It achieves precise power regulation and stable system frequency in virtual power plants, quickly eliminates power deviations, meets real-time compensation requirements, and improves the accuracy of virtual power plant response to superior commands and the stability of system frequency.
