Block Bidding Method for Clean Energy Trading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The intermittent nature of wind and photovoltaic clean energy output hinders the formation of effective market forces and competitiveness in power market transactions, making it difficult to promote clean energy consumption.
Innovation Solution
A block bidding method on a power trading platform that involves dividing clean energy units into trading periods, collecting historical data, predicting monthly electricity generation curves, decomposing annual contracts, determining transaction declarations, and executing time-slot clearing based on 'high and low matching' principles to enhance clean energy market competitiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If clean energy units participate in power trading with intermittent output characteristics, then clean energy consumption is promoted, but market competitiveness and effective market forces are hindered
Solution Approach 1:
The patent segments the power trading process into multiple time slots (e.g., peak, valley, flat periods) and divides clean energy output into block bidding units. This segmentation allows the intermittent clean energy output to be matched with corresponding demand periods, transforming unpredictable intermittent output into structured tradable blocks that enhance market competitiveness while promoting consumption.
Solution Approach 2:
The patent implements preliminary action by requiring clean energy units to declare their output blocks in advance for future time slots. This forward declaration mechanism allows market participants to plan and match demand with clean energy supply ahead of time, creating effective market forces despite the intermittent nature of clean energy generation.
2Productivity
If time-slot clearing based on high and low matching is implemented, then matching efficiency between clean energy output and demand is improved, but trading system complexity increases
Solution Approach 1:
The patent changes key parameters of the trading system by introducing time-slot-based block bidding with high and low matching principles. Instead of traditional continuous bidding, the system uses discrete time slots with declared output blocks, transforming the trading parameters to simplify the matching process while improving efficiency between clean energy output and demand.
3Reliability
If block bidding method is adopted for clean energy trading, then market competitiveness is enhanced, but data collection and processing requirements increase
Solution Approach 1:
The patent extracts essential data elements needed for block bidding by focusing on key parameters such as time slot, output block size, and pricing information. Instead of collecting and processing all possible operational data from clean energy units, the system extracts only the necessary elements for block declaration and matching, reducing data volume while maintaining market competitiveness.
