Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electricity supply apparatuses for industrial sites, particularly telecommunication sites, do not optimize battery usage, leading to potential damage and inefficient energy storage, as discharge and recharge conditions are determined by peak shift or load-levelling functions without considering hourly energy price variations.
Innovation Solution
An electricity supply apparatus with a control device that classifies hours into peak, off-peak, and neutral hours based on energy prices, adjusting the current drawn from the mains and battery usage to minimize peak hour consumption and optimize battery charging and discharging, using probes to monitor current and voltage, and a control signal to regulate the energy station's current draw.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the batteries are used for peak shift function without considering optimal charge/discharge conditions, then the current draw during peak hours is reduced, but the batteries may be damaged and energy storage efficiency is reduced
Solution Approach 1:
The control device monitors battery parameters (charge level, temperature, voltage, current) in real-time and dynamically adjusts charge/discharge parameters based on optimal conditions stored in a database. This ensures batteries operate within safe and efficient parameter ranges, preventing damage while maximizing energy storage efficiency.
Solution Approach 2:
The system implements continuous feedback by monitoring battery status through probes and adjusting charge/discharge operations accordingly. The control device uses real-time battery information to modify operational parameters, ensuring optimal conditions are maintained while preventing battery damage during peak shift operations.
2Productivity
If the energy station draws current from mains without control, then the telecommunication apparatuses are supplied, but the current draw during high-priced hours is not minimized
Solution Approach 1:
The control device dynamically adjusts the energy station's current draw from the mains based on real-time battery charge level and operational requirements. This dynamic control ensures continuous supply to telecommunication apparatuses while minimizing current draw during high-priced hours by utilizing battery discharge when appropriate.
Solution Approach 2:
The system performs preliminary charging of batteries during off-peak hours when energy prices are lower, preparing stored energy for use during peak hours. This advance action reduces the need to draw current from the mains during high-priced periods while ensuring continuous supply to telecommunication apparatuses.
3Quantity of substance
If the batteries are charged during peak hours, then the energy is stored for later use, but the cost of energy storage increases
Solution Approach 1:
The control device implements periodic charging and discharging cycles based on energy price variations and battery optimal conditions. Batteries are charged during off-peak hours when prices are lower and discharged during peak hours, creating a periodic pattern that reduces energy storage costs while maintaining adequate energy levels for peak demand.
