Power generation method using multiple dc power sources
A recently granted patent (Publication Number: US11689049B2) describes a power generation method and system that allows for efficient power delivery to a load. The method involves providing power from a first DC power source to the load through a combination of an electromechanical connection device and a diode. The level of electric energy of the source bus is monitored and compared to a load threshold to determine if the first DC power source can meet the load demand. If the first DC power source is unable to satisfy the load power demand, the second DC power source is electrically connected to the load through another combination of an electromechanical connection device and a diode.
In this method, both the first and second DC power sources can be connected to the load for a period of time, ensuring a smooth transition of power supply. Additionally, a storage system can be activated to provide power to the load if the output voltage from the first DC power source drops below the load threshold. The storage system supplies power through a load bus, maintaining a voltage equal to the base voltage.
The system includes a controller that manages the power generation process. It turns on and off the electromechanical connection devices and diodes to control the flow of power from the DC power sources to the load. The controller also determines if the first DC power source can meet the load power demand based on the level of electric energy of the source bus and the load threshold. If necessary, the controller activates the second DC power source and deactivates the storage system accordingly.
The power generation system described in the patent utilizes fuel cell power generators as the first and second DC power sources. This technology allows for efficient and reliable power delivery to the load, ensuring that the load power demand is met.
Overall, this patent presents a method and system for power generation that optimizes power supply to a load by utilizing multiple DC power sources and a storage system when needed. The controller plays a crucial role in managing the power flow and ensuring a seamless transition between power sources. This technology has the potential to improve the efficiency and reliability of power generation systems in various applications.
