Solution Overview

Problem

Existing systems struggle to effectively aggregate distributed energy resources (DERs) to provide a coordinated response to electricity providers, as they do not consider site-specific activities, DER sizes, and operating costs, leading to inefficient utilization and high costs in peak demand situations.

Innovation Solution

A centralized aggregation engine coordinates with site controllers to optimize the aggregation of DERs, adjusting benefits and participation levels to achieve a target power change while minimizing total electricity-related costs, by communicating participation opportunities and adjusting benefits based on commitment levels to ensure efficient and economic operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional VPPs aggregate DERs without considering site-specific factors, then coordination capability is improved, but cost efficiency deteriorates

Engineering Contradiction:
Improvecoordination capabilityVSAvoidcost efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system transitions from uniform aggregate control to site-specific optimization by considering individual DER characteristics, site constraints, and local operating conditions. Each DER is evaluated and controlled according to its unique properties, enabling cost-effective aggregation while maintaining coordination capability.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The aggregation system dynamically adjusts DER participation based on real-time factors including DER size, site-specific activities, operating costs, and grid conditions. This dynamic optimization allows the system to adapt to changing conditions and minimize costs while maintaining coordination.

Inventive Principle:
Principle #15Dynamics

2Reliability

If centralized control is implemented to coordinate DERs, then grid stability is improved, but system complexity increases

Engineering Contradiction:
Improvegrid stabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system introduces an aggregation layer that acts as an intermediary between individual DERs and the utility provider. This intermediary coordinates DER participation, manages complexity, and enables centralized control benefits while abstracting the complexity from both the utility and individual DER operators.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of energy

If DER participation is optimized based on site-specific factors, then cost efficiency is improved, but coordination difficulty increases

Engineering Contradiction:
Improvecost efficiencyVSAvoidcoordination difficulty
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms that provide real-time information about DER status, site conditions, and cost factors to the aggregation layer. This feedback enables the system to continuously optimize DER participation based on current conditions while maintaining coordination through automated decision-making algorithms.

Inventive Principle:
Principle #23Feedback

AI summary

Apparatuses, systems, and methods of apportioning an aggregate maneuver is disclosed. An aggregation engine receives aggregation opportunity information requesting an aggregate change in power of one or more sites. The aggregation engine transmits participation opportunity information to a plurality of site controllers. The participation opportunity information indicates a site benefit for providing a site change in power. The aggregation engine also receives commitment information from the plurality of site controllers, the commitment information indicating levels of commitment of the plurality of site controllers to contribute site change in power to a target change in power of the aggregation opportunity. The aggregation engine, as appropriate, further transmits updated participation opportunity information including an adjusted proposed site benefit, an adjusted proposed site change in power, or both to the plurality of site controllers, until an aggregate change in power of the one or more sites is within a threshold level of the target change in power.
