Control Platform for Passenger Transport Power Demand Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of renewable energy sources and increasing electricity demand poses challenges for maintaining power grid stability, particularly due to the volatility of passenger transport systems' power demand, which requires more reserve capacity from grid operators.
Innovation Solution
A control platform coordinates and optimizes power demand management across multiple passenger transport installations by determining activation orders based on available flexibility capacity and external data, transmitting specific activation signals to manage frequency regulation, and adjusting load or energy feedback to the grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If passenger transport installations operate independently with high power demand flexibility, then power consumption can be adapted to grid needs, but power demand becomes highly volatile with peaks up to 30 times average demand
Solution Approach 1:
The patent aggregates multiple independent passenger transport installations into a single controllable entity. The control platform combines power demand signals from numerous installations to create a stabilized collective load profile that smooths individual volatility while maintaining overall flexibility for grid participation.
Solution Approach 2:
The control platform acts as an intermediary between passenger transport installations and the power grid. It receives individual power demand signals, processes them through aggregation and coordination algorithms, and outputs a stabilized collective signal that can be reliably used for frequency regulation and demand response while shielding individual installations from direct grid volatility.
2Reliability
If grid operators purchase more reserve capacity to maintain grid stability, then grid stability is maintained, but costs increase and pressure on grid operators intensifies
Solution Approach 1:
The patent converts the previously harmful volatile load profile of passenger transport installations into a beneficial resource for grid stability. By aggregating and coordinating these installations, the system transforms unpredictable power demand into a controllable demand response asset that can provide frequency regulation services, thereby reducing the need for additional reserve capacity while maintaining or improving grid stability.
3Ease of operation
If passenger transport installations are controlled independently, then operational autonomy is maintained, but coordination for frequency regulation becomes inefficient
Solution Approach 1:
The patent implements a segmented control architecture where individual passenger transport installations retain operational autonomy through local control units, while a higher-level control platform coordinates them for collective frequency regulation. This hierarchical segmentation allows independent operation at the installation level while enabling efficient coordinated control at the system level for grid services.
