Coordination and Optimization Strategy of Distribution Network Loss Based on Dynamic Load Variation

Aiming at the problem of distribution network line loss, a coordinated optimization method of distribution network line loss based on dynamic load change is proposed. UPFC is used to accurately control the power flow distribution and improve the power flow distribution of transmission lines. It effectively reduces the line loss caused by three-phase imbalance, improves the transmission capacity of the line and improves the reliability of the power grid. A new three-phase power compensation circuit is added to the UPFC device, which can automatically collect the voltage and current signals in the power grid circuit and calculate the collected voltage and current signals. The control circuit generates the calculated signal information to generate a driving signal, and sends the driving information to the main circuit. The main circuit compensates the grid current according to the driving signal, and the computer controls the operation process and displays the control results. Experiments show that the designed method significantly reduces the loss in the power grid circuit, improves the utilization of active power, and provides a good environment for the stable operation of the power grid circuit.
