Shut off the main power supply.
The paper deals with controlling an autonomous electric power system that comprises of a primary source of power supply, Proton Exchange Membrane fuel cell (PEMFC), DC DC boost power converter as a power conditioner, and the ultracapacitor for an auxiliary power supply.
The combination of PV generation and a BE system, called a PV/BE station, is considered as the primary energy resource for the island power supply in this paper.

The upper level problem of the proposed bi level model represents a microgrid planner whose goal is to minimize its planning and operational cost, while the lower level problem represents a DSO whose primary duty is to ensure reliable power supply.
Similarly, the Advanced Camera for Surveys (ACS) main camera primary electronics failed in June 2006, and the power supply for the backup electronics failed on January 27 , 2007
Thus, factors such as inaccessibility to replenish power and constrained power supply have made energy consumption one of the primary issues in sensor networks.
The inference of the above routine electronic circuit behaviour is that an electrical power supply system, at the national grid level, should function adequately with intermittent renewables acting as the primary power sources, provided the supply side is buffered from the demand side by massive energy storage (MES) plants, such as pumped hydroelectric schemes.
Electric power security relies on the security of primary energy supply, whereas, the production, transportation, control and some other aspects of other energy systems are affected by the electric power supply.
