Power Plant Load Distribution and Market Bidding Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power plant operations struggle with efficient load distribution and bidding strategies in response to power supply and demand adjustments, often compromising generator efficiency due to non-optimal load distribution and bidding decisions.
Innovation Solution
A supply/demand adjustment control device and method that acquires power requests, distributes loads to generators based on operation efficiency, and determines bidding strategies to maximize rated load operation and ensure efficient power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load is distributed equally among multiple generators when requested load decreases, then power supply request can be met, but operation efficiency of generators is compromised
Solution Approach 1:
The patent applies local quality by distributing load non-uniformly across generators based on their individual characteristics and current operating states. Instead of equal load distribution, the control device calculates optimal load allocation for each generator to maintain operation efficiency while meeting total power supply requirements, particularly when requested load decreases.
Solution Approach 2:
The patent changes the load distribution parameters dynamically based on requested load conditions. When requested load decreases, the system adjusts load allocation to concentrate power on fewer generators operating near rated load, rather than maintaining equal distribution across all generators, thereby preserving operation efficiency.
2Speed
If bid is made without considering load distribution and operation efficiency, then bidding response is quick, but economic efficiency is reduced
Solution Approach 1:
The patent implements preliminary action by pre-calculating load distribution and operation efficiency assessment before making bidding decisions. The control device determines whether to respond to power supply requests based on anticipated load distribution impacts, ensuring that bidding decisions are made with full awareness of their effect on generator operation efficiency, thus avoiding rushed decisions that compromise economic efficiency.

AI summary
Provided is a control device that calculates load distribution to a generator having excellent operation efficiency and determining whether to make a bid in response to a request for power supply from a power supply and demand adjustment market. A supply/demand adjustment control device includes: an acquisition unit that acquires first power requested for a power plant including a plurality of generators and second power requested from a power supply and demand adjustment market; a load distribution unit that distributes a total load that is a sum of the first power and the second power to the plurality of generators in descending order of operation efficiency, to distribute a load close to a rated load as much as possible to the generators; and a bidding determination unit that determines whether to make a bid for a request from the power supply and demand adjustment market, on the basis of whether the total load is able to be supplied.
