An Algorithm Based on Consensus for Active Power Sharing and Voltage Regulation Within Electrical Distribution Networks

Currently, the integration and coordination of a high quantity of distributed generators (DG) into traditional electrical distribution networks has introduced technical challenges to maintain electrical parameters, such as voltage and frequency, within acceptable levels. Distributed control schemes offer a promising solution to handle the computational demands of coordinating numerous DG units, enabling direct data sharing among DGs and simpler communication structures. This paper proposes a distributed control approach based on a leader-follower consensus algorithm to ensure voltage regulation across all grid buses. By regulating the active power injected by the DGs, the method aims to achieve consensus among the units and adjust power generation to maintain uniform operation. Simulations on the IEEE 34-bus network demonstrate the effectiveness of the proposed method under various load conditions, and in all cases where the proposed method was applied, the voltage was maintained within the allowed limits across all phases.
