摘要：
Active distribution networks will meet new challenges in voltage and congestion control due to the high penetration levels of distributed generations (DG). Optimal voltage control techniques are mainly based on the relation between the network voltages and control variables (i.e. power injection). Thus, in this paper, a centralized real time scheme using a fast method for computing the sensitivity coefficients is presented to control congestion and voltage problems. The sensitivity coefficients of network voltages as well as the branch line currents are obtained via direct analytical derivation. A 11KV, 75-bus distribution system including several DGs is used to validate the proposed method. Simulation results show that the proposed method is able to maintain the network voltages and line currents within acceptable limits.
