Power Source Distribution Ratios for Grid Adjustability Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power control systems face challenges in proportionally distributing required adjustability during planning periods to absorb forecast errors and demand response, which can disrupt regional power supply and demand balance.
Innovation Solution
A distribution apparatus and method that acquires information on costs or carbon dioxide emissions for various power sources, sets a distribution ratio for each power source to optimize adjustability, and outputs setting values by time period, allowing for proportional distribution of required adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a facility operation plan is developed to cover electrical energy shortfall and minimize costs, then power supply and demand balance is maintained, but forecast errors and demand response disruptions cannot be effectively absorbed
Solution Approach 1:
The required adjustability is segmented and proportionally distributed to multiple power sources based on their characteristics and capabilities. This allows the system to maintain overall balance while enabling individual power sources to contribute differently to absorbing forecast errors and demand response, thus resolving the contradiction between maintaining balance and providing adaptability.
2Adaptability or versatility
If required adjustability is concentrated in single power source, then forecast errors can be absorbed, but system complexity and operational difficulty increase
Solution Approach 1:
The adjustability requirement is divided and distributed across multiple power sources rather than concentrated in one. This segmentation reduces the burden on individual components and simplifies operational management while maintaining the overall adaptability needed to absorb forecast errors.
3Ease of operation
If traditional power control is used without proportional distribution, then operational simplicity is maintained, but cost efficiency and carbon emission reduction are insufficient
Solution Approach 1:
The system changes the operational parameters of power sources dynamically based on real-time conditions such as cost factors and carbon emission intensities. By adjusting the distribution ratio of required adjustability according to these parameters, the system achieves improved cost efficiency and emission reduction while maintaining operational simplicity through automated control.
