A power control system that includes a storage cell and a power control apparatus, allowing allocation of predetermined storage capacities to consumer facilities, enabling charging and discharging instructions to be received and managed, thereby optimizing power usage and reducing electricity charges through virtual storage cell utilization agreements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a base-load power source is used to generate power throughout the year, then stable power supply is achieved, but oversupply occurs during late night hours when demand decreases
Solution Approach 1:
The stationary storage cell charges in advance during late night hours when power demand is low and electricity rates are reduced, storing surplus power generated by the base-load power source. This preliminary action prevents energy waste by capturing excess power before peak demand periods occur.
Solution Approach 2:
The system changes the temporal distribution of power consumption by shifting charging operations to late night hours and discharging during daytime peak demand periods. This parameter change in consumption timing resolves the contradiction between stable power supply and energy oversupply.
2Loss of energy
If consumers shift power demand to late night hours to reduce electricity charges, then cost savings are achieved, but the need for stationary storage cells increases initial investment costs
Solution Approach 1:
The stationary storage cell serves multiple functions: it stores power during low-demand periods, supplies power during peak demand periods, and enables consumers to benefit from reduced electricity charges. This multi-functionality justifies the initial investment by delivering diverse value.
Solution Approach 2:
The storage cell autonomously manages charging and discharging operations based on power demand patterns and electricity rate structures, automatically shifting power consumption to achieve cost savings without requiring complex external control systems.
3Productivity
If a stationary storage cell is installed at consumer facilities, then power demand can be shifted to low-rate periods, but initial installation costs increase
Solution Approach 1:
The controller receives information about power demand patterns and electricity rates, then adjusts charging and discharging operations accordingly. This feedback mechanism optimizes power demand management to maximize cost savings and justify the initial installation investment.
Solution Approach 2:
The storage cell system dynamically adapts its operation based on varying power demand conditions and electricity rate structures, shifting charging and discharging timing to optimize economic benefits and productivity.
