Abstract: Abstract：In the AC/DC distribution network of coal mines with distributed power sources such as photovoltaics, there are factors that cause DC voltage fluctuations, such as uneven illumination and load fluctuations. In order to reduce the influence of these fluctuations on system stability, this paper proposes a control strategy that introduces the photovoltaic output voltage and motor load current as feed-forward links on the basis of the traditional single-loop control structure of photovoltaic system. Attenuate DC link voltage fluctuations caused by these two factors. A simulation model of AC/DC hybrid distribution network in coal mines is built in PSCAD/EMTDC, and the effectiveness of the proposed control strategy is verified by comparing the maximum power point tracking (MPPT) control strategy, MPPT-traditional voltage regulation switching control strategy and the DC bus voltage characteristics under the control strategy proposed in this paper.
