A control unit manages power sources and energy storage in a hybrid power generation system. The hybrid power generation system is configured to meet a power demand of one or more electrical loads, and has a primary power source with one or more fuel cells to convert hydrogen to electrical power, a secondary power source comprising a combustion engine and a generator to generate to convert fuel into electrical power, and an energy storage system to support the primary and secondary power sources. The control unit monitors the power demand of the one or more electrical loads, and upon detecting a spike in the power demand, connects the energy storage system to support at least one of the primary and secondary power sources.

Method for controlling at least one power source (1), the at least one power source (1) supplying electrical power to at least one power consumer (3) via an electrical power supply grid (2), wherein the following steps are carried out: measuring and/or determining electrical quantities, preferably a frequency and a power disturbance, of the power supply grid (2) during a time period where the electric power supply grid (2) is excited and/or perturbed, such that there is a frequency deviation from a nominal frequency of the power supply grid, deriving at least one parameter (H,D,K.sub.P,K.sub.I,K.sub.D) of a dynamic grid response model from measured values and/or determined values of the measurement and/or determination of the electrical quantities of the power supply grid (2), and adapting a control algorithm defining a control response of the at least one power source (1) depending on the at least one parameter (H,D,K.sub.P,K.sub.I,K.sub.D) of the dynamic grid response model.

A system is disclosed for monitoring a modular electrical power plant, the modular electrical power plant including at least two power generation units and an auxiliary system. The system for monitoring a modular electrical power plant includes a plurality of data collection channels for receiving data describing operating conditions of the at least two power generation units and a processing unit configured to generate a user interface. The user interface includes a single power generation unit view and a multiple power generation unit view. The processing unit is configured to select between the single power generation unit view and multiple power generation unit view based on the data describing the operating conditions of the at least two power generation units.
