Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Renewable energy generators face challenges due to curtailment, where excess power is wasted as it cannot be transmitted to the grid, leading to economic losses and inefficiencies, especially for wind and solar generators with high capital costs and no fuel costs, while fossil generators have higher variable costs.
Innovation Solution
A system that includes behind-the-meter vehicle charging stations and flexible datacenters capable of dynamically modulating power delivery based on monitored power system conditions and operational directives, utilizing both generated and stored behind-the-meter power to avoid transmission and distribution costs, and allowing for granular ramping up or down of electrical loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If curtailment is implemented to manage grid stability and transmission congestion, then grid stability is maintained, but renewable energy generation is reduced and economic losses occur
Solution Approach 1:
The system performs preliminary actions by notifying users in advance of curtailment events and providing options to pre-charge vehicles or pre-cool buildings before power is reduced. This allows load management to occur before the curtailment takes effect, maintaining grid stability while minimizing impact on renewable energy utilization.
Solution Approach 2:
The system dynamically adjusts power delivery based on real-time grid conditions, user preferences, and load requirements. It modulates power between behind-the-meter sources and grid connections, and adjusts the timing and magnitude of curtailment actions to balance grid stability needs with renewable energy utilization.
2Loss of energy
If behind-the-meter power is utilized locally, then transmission losses are reduced and renewable energy waste is minimized, but device complexity increases
Solution Approach 1:
The control system performs multiple functions including monitoring grid conditions, managing behind-the-meter power sources, coordinating with flexible loads, providing user notifications, and executing curtailment strategies. This multi-functionality consolidates complex power management capabilities into a single integrated system, reducing overall system complexity while maximizing local power utilization.
Solution Approach 2:
The system introduces a control system as an intermediary between power generation sources and flexible loads. This intermediary coordinates power flow, manages curtailment events, and provides user interfaces, simplifying the complexity of directly managing multiple distributed energy resources and flexible loads without centralized control.
3Productivity
If flexible loads are ramped up or down dynamically, then renewable energy utilization is improved, but ease of operation decreases
Solution Approach 1:
The system continuously monitors grid conditions, power availability from behind-the-meter sources, and flexible load status. It provides real-time feedback to users about curtailment events, power availability, and system actions taken. This feedback mechanism automates complex load management operations while keeping users informed, improving renewable energy utilization without requiring users to manually manage flexible loads.
Solution Approach 2:
The system enables flexible loads to self-adjust based on automated control signals and pre-configured user preferences. Loads are ramped up or down automatically in response to curtailment events without requiring manual user intervention. Users simply define their preferences and constraints, and the system autonomously manages the complex operations of coordinating multiple flexible loads with renewable energy availability.
