Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in accurately calculating and promoting the consumption of renewable energy, particularly in assigning and utilizing environmental values for power generated from renewable sources, especially when charging and discharging processes are involved.
Innovation Solution
A power management system that includes a power supply system and a power demand-supply management apparatus, which manages transactions of renewable energy by requesting power supply in the generation time zone and issuing certificates for consumed power, enabling accurate tracking and promotion of same-time renewable power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the buyer consumes power generated by energy to which environmental value is not assigned in combination, then the buyer can consume power flexibly, but it becomes difficult to calculate the usage amount of power generated by energy to which environmental value can be assigned
Solution Approach 1:
The patent segments the power consumption into different components: power consumed directly from renewable energy sources, power consumed from other sources, and power supplied to other apparatuses. By dividing the power flow into distinct segments and tracking each separately, the system can accurately calculate environmental values even when multiple power sources are combined, thus resolving the contradiction between consumption flexibility and measurement accuracy.
Solution Approach 2:
The patent introduces a management apparatus as an intermediary that tracks and manages power flow between the renewable energy source, the buyer's apparatus, and other apparatuses. This intermediary system maintains records of power generation, consumption, and transfer, enabling accurate environmental value calculation while allowing flexible power consumption patterns including charging and discharging operations.
2Adaptability or versatility
If the buyer charges a charge/discharge apparatus with power and further supplies a part of the charged power to another apparatus, then the buyer can utilize power flexibly across different time zones, but it becomes difficult to accurately calculate the environmental value
Solution Approach 1:
The patent segments the power transaction into distinct phases: charging phase (when renewable power is stored), discharge phase (when stored power is released), and consumption phase (when power is used by various apparatuses). Each phase is tracked separately with detailed records, allowing the system to calculate environmental values accurately even when power is moved across different time zones and apparatuses.
Solution Approach 2:
The management apparatus acts as an intermediary that oversees the entire charge-discharge-consumption cycle. It maintains a comprehensive record of power flow, tracking which apparatus charged the energy storage device, how much power was stored and discharged, and which apparatus ultimately consumed the power. This intermediary tracking enables accurate environmental value calculation while supporting flexible cross-time-zone power utilization.
3Measurement precision
If the system encourages consumption of renewable power in the same time zone, then environmental value calculation becomes more accurate, but the adaptability of power consumption is reduced
Solution Approach 1:
The patent segments power consumption into same-time consumption (when renewable power is consumed in the generation time zone) and different-time consumption (when power is stored and consumed later). The system prioritizes same-time consumption for accurate environmental value calculation while still permitting different-time consumption through charge/discharge operations, thus balancing measurement accuracy with consumption flexibility.
Solution Approach 2:
The system dynamically adjusts power consumption strategies based on various factors such as environmental value targets, power availability, and user needs. While encouraging same-time consumption for accuracy, the system flexibly allows charge/discharge operations and different-time consumption when appropriate, making the power consumption pattern adaptable rather than rigid, thus resolving the contradiction between precision and versatility.

AI summary
A power management system, which manages a transaction of power generated based on renewable energy, includes: a power supply system capable of supplying power generated based on the renewable energy to a power demand system; and a power demand-supply management apparatus that manages demand and supply of the power. The power demand-supply management apparatus requests the power supply system to supply the power to the power demand system in a power generation time zone of the power, and issues, to the power demand system, a certificate that an amount of supplied power has been consumed in accordance with generation of the power.
