Abstract

The invention belongs to the field of virtual synchronous motor control and particularly relates to a virtual synchronous generator control method based on droop coefficient adaptive adjustment. The problem that electrical equipment is sensitive to the change of a frequency and a voltage amplitude, and a VSG can maintain the balance of the microgrid power facing the change of a microgrid load in an off-grid operation mode, and the no-deviating regulation of the frequency and the Small deviation of phase voltage amplitude adjustment are achieved.

Description

technical field

[0001] The invention belongs to the field of virtual synchronous motor control, and in particular relates to a virtual synchronous generator control method based on droop coefficient self-adaptive adjustment. Background technique

[0002] As energy shortages and environmental pollution have seriously affected social and economic development, economical, clean, renewable wind energy, solar energy and other new energy sources have received more and more attention. With the rapid growth of new energy grid-connected installed capacity, the stability of traditional power system operation is facing a huge threat due to the nonlinear and random fluctuations of distributed power generation. Distributed power supply is a static device because there are no rotating components in its circuit. Compared with traditional synchronous generators, distributed power supply lacks the rotating reserve capacity and moment of inertia to maintain the overall energy balance of the g...
