Abstract For radiation distribution networks with distributed photovoltaic access, combined with the photovoltaic local voltage-var control strategy, a fast power flow calculation method is proposed. This method has a concise linear expression and could approximated power flow solutions. In this paper, through compression mapping theorem and matrix theory, it is rigorously demonstrated that the power flow solutions obtained by the proposed method is the practical feasible solutions to the system. The method was tested by a 56-node system and compared with the existing calculation method of distribution network. Moreover the influence of network parameters on the establishment of the proposed rapid power flow calculation method and the accuracy of the calculation results are analyzed. The simulation results indicated that the proposed method could be well applied to the analysis of the radiation distribution networks with distributed photovoltaic access.

Key words： Distributed photovoltaic radiation distribution network fast power flow calculation compression mapping theorem matrix theory
