On-grid/off-grid seamless switching control method and device for renewable energy hydrogen production system |
| abstract |
The invention discloses a method and a device for seamless switching control method and device of a renewable energy hydrogen production system considering harmonic suppression. Firstly, according to the different harmonic characteristics and control objectives of the renewable energy hydrogen production system in the two operating modes, an impedance adjustment control strategy suitable for the island mode and a harmonic compensation control strategy suitable for the grid-connected mode are proposed. Subsequently, the methods of improving the voltage outer loop and improving the phase-locked loop were introduced to the energy storage converter with the isolated grid voltage and frequency, so as to realize the smooth transition of the bus voltage of the renewable energy hydrogen production system during the switching process. The method can realize seamless switching between grid-connected/islanding operation modes of the renewable energy hydrogen production system under the nonlinear hydrogen production load and harmonic power grid, and can work in both grid-connected/islanded operation modes for the renewable energy hydrogen production equipment. Provide a reference for safe operation in mode. |
