Abstract

The higher the penetration level of PVs in distribution networks, the greater the overvoltage issues would be. Due to the extremely high dimension of control variables, the traditional centralized control methods are getting too complex, which would barely satisfy the operational requirements of future active distribution networks. In order to address this crucial issue, this paper presents a voltage control method based on a network partitioning technique. A community detection algorithm based on a reactive/active quality function is introduced to divide a distribution network into reactive/active power sub-networks. For the reactive power sub-networks, a second-order cone programming （SOCP） based model for PV inverters is established with the objective of minimizing the regulated reactive power. For the active power sub-networks, a SOCP based model is also proposed for PV inverters with the objective of minimizing the curtailed active power of PVs. The proposed models in each sub-networks are solved by a parallel way. After the optimization, the results of the optimization are exchanged among each sub-network, and the constraints in each sub-network are then updated accordingly. A new optimization process is then started until the stopping criterion is met. Finally, an actual feeder is employed to verify the feasibility and effectiveness of the proposed approach.
