In order to make full use of the distributed photovoltaic reactive power regulation ability to participate in the voltage coordination control of active distribution network and to improve the effectiveness and stability of voltage regulation
a voltage control strategy of active distribution network considering distributed photovoltaic reactive power margin is proposed in this paper. Firstly
based on the voltage sensitivity matrix
the interaction mechanism between distributed photovoltaic power control and node voltage change is clarified in detail
so as to determine the compensation priority of each node. Secondly
based on the reactive power regulation ability and voltage regulation sensitivity of distributed photovoltaic
the reactive power regulation margin index of distributed photovoltaic is established. Then
considering the reactive power regulation margin index and the compensation priority of the node
the voltage control model is established
and the voltage control model is solved efficiently by the particle swarm optimization algorithm with the precoding technology. Finally
the feasibility and effectiveness of the proposed method are verified by the simulation of the modified IEEE33-node system.
