A system and method of power management for a power generation system is disclosed. A method of power management for a hydrogen generation system including one or more electrochemical stacks, the one or more electrochemical stacks receiving power from an electrical grid including at least one power source, includes: receiving a frequency or voltage reference value for the hydrogen generation system; continually monitoring a frequency or voltage of the electrical grid; and varying a load of the hydrogen generation system in response to the frequency or voltage of the electrical grid differing from the frequency or voltage reference value to restore the frequency or voltage of the electrical grid to the frequency or voltage reference value.

Frequency droop to coordinate hydrogen production

An alternating current (AC) impedance spectroscopy method includes providing an AC impedance spectroscopy ripple from power electronics into an electrochemical device, and absorbing the ripple in the power electronics.

Impedance monitoring of a modular electrolysis system

A system for controlling a photovoltaic (PV)-powered hydrogen production plant includes a plurality of PV modules to receive sunlight and output DC power, wherein the plurality of PV modules are combined in series to create a PV string, at least one power cabinet comprising at least one DC-to-DC power converter to receive DC power from the PV string and provide regulated DC power to an electrolyzer stack, the regulated DC power having regulated output current and/or voltage, and at least one controller to control the at least one DC-to-DC power converter to match the regulated DC power to requirements of the electrolyzer stack.

System and methods for controlling photovoltaic-powered hydrogen production plants

The present disclosure relates to circuits for connecting components of a hydrogen plant to a power grid to power the components in an efficient manner. In one implementation, power-side alternate current (AC) to direct current (DC) converters may be connected to a source power grid without the need for an isolation transformer by providing separate buses between the power-side AC-DC converters and load-side DC-DC converters instead of a shared DC bus between the converters. Other implementations for connecting components of a hydrogen plant to a power grid may include an adjustable transformer, such as a tappable transformer or an autotransformer, to connect any number of auxiliary loads of the plant to the power grid. The adjustable transformer may provide for various types of auxiliary load devices to connect to the power provided by the transformer at the same time, including both three-phase devices and one-phase devices.
