Battery Charge-Discharge Planning for Grid Quality and Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing storage batteries struggle to balance the usability of consumer batteries for both grid power quality and individual consumer needs, as the remaining power must be maximized to handle charge/discharge commands, leading to reduced consumer flexibility and efficiency.
Innovation Solution
A charge/discharge plan creation device that determines constraint conditions based on predicted charge/discharge amounts and computes plan values to manage the variation in remaining power, allowing for dynamic adjustment of battery usage to meet both grid demands and consumer needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remaining power of storage batteries is maximized to handle charge/discharge commands for securing power grid quality, then the reliability of power grid quality securing is improved, but the usability of storage batteries for consumers deteriorates
Solution Approach 1:
The patent applies dynamics by making the charge/discharge control strategy adaptable and changeable based on real-time conditions. The system dynamically switches between different control strategies (prioritizing grid quality vs. prioritizing consumer usability) depending on the state of storage batteries and power grid needs, rather than using a fixed control approach. This allows the system to optimize between reliability and usability at different times.
Solution Approach 2:
The patent changes the control parameter from a fixed 'maximize remaining power' approach to a flexible parameter that can be adjusted between prioritizing grid quality and consumer usability. By introducing a controllable parameter that determines the degree of charge/discharge control, the system can adapt to different operational requirements and balance the contradiction between grid reliability and consumer convenience.
2Reliability
If a margin is set for the chargeable/dischargeable amount to cope with maximum possible commands, then the reliability of responding to power grid requests is improved, but the productivity of storage battery usage for consumers deteriorates
Solution Approach 1:
The patent applies partial action by implementing selective control over charge/discharge operations. Instead of always maintaining maximum margin for grid requests, the system applies control only when necessary for power grid quality, allowing consumers to utilize their storage batteries fully during periods when grid support is not required. This partial application of control resolves the contradiction by avoiding excessive restriction on consumer productivity.
3Adaptability or versatility
If the chargeable/dischargeable amount is secured with margin in both charge and discharge, then the adaptability of storage batteries to power grid requests is improved, but the ease of operation for consumers deteriorates
Solution Approach 1:
The patent implements periodic evaluation and adjustment of charge/discharge control based on varying power grid conditions and consumer needs. The system periodically assesses whether grid quality securing is currently prioritized or consumer usability is prioritized, allowing consumers to experience periods of full control over their storage batteries when grid support is not urgently needed, thus improving ease of operation while maintaining adaptability when required.
