GPU Parallel Processing for Demand Response Scalability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing demand response management systems face scalability challenges as the number of participants grows, leading to increased costs and resource constraints due to the inability to efficiently execute participant-specific DR logic on a single server.
Innovation Solution
The use of graphical processing units (GPUs) to parallelize the processing of demand response information and rules across multiple participants, allowing for concurrent execution of DR logic and significant performance increases at a fraction of the cost of additional servers.

Engineering Contradiction Analysis
1Productivity
If traditional central processing units (CPUs) are used to process demand response logic for each participant, then system reliability is maintained, but processing speed and throughput decrease significantly as the number of participants grows
Solution Approach 1:
The patent replaces traditional CPU-based sequential processing with GPU-based parallel processing. The GPU's architecture with thousands of smaller cores enables simultaneous execution of multiple participant-specific DR logic operations, transforming the processing mechanism from sequential to parallel, thereby dramatically increasing throughput and reducing processing time.
Solution Approach 2:
The patent segments the demand response processing workload into individual participant-specific logic executions that can be distributed across multiple GPU cores. Each core independently processes a portion of the participant data, allowing concurrent execution and eliminating the bottleneck of sequential CPU processing.
2Productivity
If additional servers are added to handle more participants, then processing capacity increases, but system cost increases proportionally
Solution Approach 1:
The patent makes a single server with GPU capability perform multiple processing functions simultaneously by leveraging the GPU's parallel architecture. Instead of requiring separate servers for different participant groups, the GPU can concurrently handle logic for all participants across multiple cores, making one server universally capable of handling the entire participant load.
Solution Approach 2:
The patent merges the processing capabilities of multiple potential servers into a single server equipped with GPU technology. The GPU consolidates the computational power that would otherwise require multiple separate server units, combining resources to achieve the same or greater processing capacity with fewer physical units.
3Ease of operation
If participant-specific DR logic is executed sequentially on a single server, then device complexity is minimized, but processing speed decreases
Solution Approach 1:
The patent introduces dynamic parallel processing capabilities to the previously static sequential execution model. The GPU architecture dynamically allocates multiple cores to handle different participant logic simultaneously, transforming the system from a static single-threaded approach to a dynamic multi-threaded parallel approach, thereby increasing speed without significantly increasing operational complexity.

AI summary
A system and approach for utilizing a graphical processing unit in a demand response program. A demand response server may have numerous demand response resources connected to it. The server may have a main processor and an associated memory, and a graphic processing unit connected to the main processor and memory. The graphic processing unit may have numerous cores which incorporate processing units and associated memories. The cores may concurrently process demand response information and rules of the numerous resources, respectively, and provide signal values to the main processor. The main processor may the provide demand response signals based at least partially on the signal values, to each of the respective demand response resources.
