Abstract:
In order to improve the ability of the distribution network to absorb distributed photovoltaics, a distribution system including distributed photovoltaics and centralized energy storage was established in the DIgSILETN platform, and distributed photovoltaics were developed from the aspects of distribution network voltage distribution and coordinated control. Operational adaptability analysis of access to distribution network. The data modeling of a 10kV feeder of a distribution network in Dali, Yunnan was selected, and the voltage distribution characteristics in steady-state operation mode and the voltage, current, active and reactive power characteristics in transient operation mode were simulated and calculated, and the proposed model was verified. Correctness and effectiveness of active distribution network operation strategies.Finally, the effect and characteristics of two controllers are verified by simulation.
