As the output power of distributed photovoltaic(PV)has the characteristics of intermittent

fluctuant and uncertain because of environmental impact

its dispersion and high-penetrating integration into distribution network has raised the problems of high dimension and high complexity. Thus a multi-level dispatching and control of active distribution network based on distributed PV virtual cluster is proposed. Firstly

the concept of virtual cluster is clarified

and a dynamic method for distributed PV virtual cluster partition based on community theory is proposed. Then considering the operation characteristics and control requirements of distribution network with high penetration of distributed PV

the specific studies of control model and implement method including global optimal scheduling

cluster optimal control strategy and local consumption control are given. Finally

a simulation model is built and a case study is analyzed in MATLAB/Simulink. The simulation results show that the proposed method can adapt to the dynamic operating state of distribution network with high-penetrated distributed PV and improve the speed and efficiency of dispatching and control for distribution network.
