Coordinated Voltage Control Using Tiered Weight Coefficients of Optimization Targets
Considering the locality feature of voltage control problems, This paper proposes a coordinated voltage control method with tiered weight coefficients of optimization targets, the optimization problem is formulated and solved based on the model predictive control method. At the initial control time, the correlation degree between buses is obtained based on the dynamic voltage response feature and fuzzy clustering method and the weak buses are identified according to the predicted system trajectory. In the optimization objective function, the higher correlation degree between the controlled buses and the weak buses leads to lager weight coefficients of the corresponding voltage deviation terms. In a fault scenario, the weight coefficients of the optimization targets are tiered-distributed, and the simulation results of the Nordic32 52-bus test system shows that the proposed method remarkably reduces optimization scale under the premise of a global control performance.
