In order to solve the voltage violation problem in a distribution network that integrates multiple distributed generators, this paper proposes a method based on distributed model predictive control for coordination of PVs and energy storage systems and for dynamic voltage regulation in a distribution network containing distributed energy storage systems. Firstly, we analysis dynamic characteristics of distributed PVs, energy storage systems and voltage sensitivity model of the distribution network, and construct the whole distribution network model considering dynamic characteristics. Considering large scale and numerous devices of distribution network, we divide it into several subsystems through ε decomposition. Then, this paper designs distributed model predictive controller containing various limits of PVs and energy storage systems and transfers this into solving a QCQP problem to optimize control instructions, and then restoring from voltage violation fast in distribution network. Finally, the simulation result in IEEE 33-node network verifies the validity of proposed method.
