Solution Overview

Problem

The electric power grid faces inefficiencies and instability due to limited energy storage, reliance on peak power, and integration of intermittent renewable sources, necessitating improved methods for dispatching and managing energy distribution, particularly for peak demand and renewable resource integration.

Innovation Solution

A comprehensive operating plan using after-the-fact analysis for performance evaluation and root-cause impact analysis, coupled with a scheduler engine that processes actual system and resource conditions from a relational database to optimize energy dispatch and scheduling, incorporating tools for renewable resource management and demand response.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If distributed electric resources are aggregated to meet medium- and large-scale needs, then productivity and resource utilization improve, but device complexity and system provisioning requirements increase

Engineering Contradiction:
Improveresource aggregation capabilityVSAvoidprovisioning complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a virtual power plant (VPP) as an intermediary layer between distributed electric resources and the utility grid. The VPP aggregation software creates a virtual entity that consolidates control and management of multiple small-scale resources (HVAC systems, water heaters, EV batteries) without requiring physical aggregation infrastructure. This intermediary handles provisioning, coordination, and grid interaction, reducing the complexity burden on individual components while enabling large-scale resource aggregation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If after-the-fact analysis is implemented for performance evaluation, then measurement precision and operational insight improve, but loss of time for data processing and analysis increases

Engineering Contradiction:
Improveperformance metric accuracyVSAvoidanalysis processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by continuously collecting, validating, and preprocessing operational data from distributed resources and grid systems in real-time as events occur. Data is normalized, stored in structured formats, and pre-aggregated into meaningful metrics before analysis is needed. This preliminary data preparation eliminates the need for time-consuming data gathering and cleaning during after-the-fact analysis, enabling rapid generation of performance evaluations and root-cause insights.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If real-time dispatch optimization is implemented, then productivity and cost efficiency improve, but device complexity and computational requirements increase

Engineering Contradiction:
Improvedispatch efficiencyVSAvoidscheduling system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic scheduling through the VPP dispatch software that continuously adapts dispatch decisions based on real-time changing conditions including grid demand, resource availability, weather patterns, and pricing signals. The system uses dynamic optimization algorithms that recalculate optimal dispatch strategies as conditions change, rather than relying on static pre-planned schedules. This dynamic approach enables real-time efficiency improvements while the modular software architecture manages computational complexity through incremental optimization.

Inventive Principle:
Principle #15Dynamics
