Abstract: With the development of active distribution networks, the impact of communication conditions on voltage control becomes more significant. The interruption in communication between the main station and photovoltaic inverters will affect the adjustment of inverter reactive power, resulting in voltage violations in the distribution network. This paper proposes a hierarchically coordinated voltage control method for active distribution networks considering the communication conditions which models the cyber side of the distribution network to describe the information interaction during the control process. Then, the reasonable adjustment of the reactive power output for each inverter in different communication conditions is realized through the coordination of the central and local hierarchies. The central hierarchy establishes the droop output constraint for inverters considering communication conditions, the power flow constraints of distribution networks, and the multi-objective function considering both network loss and voltage deviation, and the linear optimization problem is solved. The local hierarchy selects droop parameters decided by the centra hierarchy or pre-set based on the inverter communication conditions. By the simulation analysis on IEEE 118-bus system, it is verified that the proposed method can ensure that the voltage of the distribution network remains within the normal range during communication interruptions, while achieving the global optimization of network loss and voltage distribution.
