Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device directly uses electric energy from the power station through the power grid, then the device can maintain continuous power supply, but the power costs become huge due to peak hour pricing
Solution Approach 1:
The power storage device charges during off-peak hours when electricity prices are low, storing energy in advance for use during peak hours. This preliminary energy accumulation allows the device to avoid high peak hour pricing while maintaining continuous operation
Solution Approach 2:
The power storage device acts as an intermediary between the power grid and the device, buffering the direct connection. It absorbs price fluctuations by charging during low-price periods and discharging during high-price periods, mediating the power supply to reduce overall costs
2Reliability
If the power station maintains stable power generation capacity, then the power supply is reliable, but the redundant power generation capacity cannot be utilized during off-peak hours
Solution Approach 1:
The power storage device recovers the redundant power generation capacity that would otherwise be wasted during off-peak hours by charging during these periods. This recovered energy is then utilized during peak hours, transforming the loss into a useful resource
3Productivity
If the power grid increases electricity price during peak hours to balance load, then the load balancing is achieved, but the power costs for devices increase significantly
Solution Approach 1:
The device performs preliminary energy accumulation by charging the power storage device during off-peak hours when electricity prices are low. This advance preparation allows the device to operate during peak hours without incurring high electricity costs, effectively bypassing the price increase mechanism

AI summary
This application provides example methods and systems for supplying power to a device, and example related devices, and relates to the field of energy technologies. One example method includes predicting power load of the device in a first electricity price interval, where the first electricity price interval is a continuous time period in which electricity prices are the same. A power supply policy can then be selected for the device based on the power load of the device in the first electricity price interval, a quantity of stored electric charges of a power storage device at a first moment, and an electricity price at the first moment. Power can then be supplied to the device based on the selected power supply policy.
