This invention relates to a modular voltage regulator and its control method, as well as a DC power supply system for new energy power. The voltage regulator circuit of the voltage regulator adopts a modular design, and the voltage regulator modules are switched on and off in priority according to the predicted or measured load of the control bus. The voltage regulator controller controls the output of the voltage regulator circuit through the feedback control parameters of the DC / DC converter unit. When the charging circuit is in floating charging or equalizing charging state, the corresponding set feedback control parameters are used. When the charging circuit is in a locked state, the feedback control parameters are determined by the predicted results of the DC bus load or the DC bus load and load change rate, as well as the real-time energy storage of the energy storage circuit. This invention achieves dynamic optimization of the control model and control function, which is beneficial to improving output characteristics, extending product life, and is suitable for applications with limited space and relatively harsh environmental conditions, such as offshore wind power. It can mainly be used as an uninterruptible DC power supply for new energy power systems.
