A system and method for collecting renewable energy includes a solar panel and a down-sun wind turbine that are mounted on a same crossbeam. In this combination, as the crossbeam is rotated on a support pole, the solar panel is simultaneously rotated through a directional arc and an inclination arc in accordance with a predetermined daily schedule that is based on the time of day and the latitude of the system. Also, as the solar panel is moved, the wind turbine is free to follow wind direction and maximize its collection of wind energy. To further maximize the energy collection capability of the system, the wind turbine is located on the crossbeam to remain down-sun from the solar panel and to remain free from wind flow interference that may be caused by the solar panel.

A system and method for an alternative power system that uses a dynamo with a centrifugal fan and solar panel connected in parallel to recharge multiple batteries simultaneously. As the vehicle operates on the Alternative Power System, the power discharging controller utilizes battery A. In parallel, the dynamo with a centrifugal fan and a solar panel recharge battery B and battery C. A charging controller manages this recharging functionality. When battery A, which supplies power to motor, is reduced to a certain level, a power discharging controller automatically switches to battery B, and the charging controller connects automatically to battery A and recharges battery C and battery A. When battery B is reduced to a certain level, the power discharging controller switches to battery C. Then, charging controller connects automatically to battery B and recharges battery A and battery B.

The present disclosure provides a scheduling method, system, electronic device, and medium for addressing power shortages, comprising: step S1: classifying demand-side flexible resources; step S2: constructing a day-ahead-and-intraday optimization scheduling mechanism for demand-side resources to participate in system regulating; step S3: modeling demand-side flexible resources; step S4: aggregating regulating abilities of the Class II load; and step S5: constructing an intraday optimization scheduling model based on a total cost of purchasing electricity from other power grids and a total cost of dispatching load-side resources. The present disclosure classifies demand-side resources and constructs an optimization scheduling mechanism, effectively dispatching different types of regulating resources to participate in optimization scheduling, balancing cost of purchasing electricity from outside the province and dispatching resources within the province, considering uncertainty of adjustability of distributed resources making the model more accurate and practical, thereby reducing cost of scheduling during power shortage.
