Solution Overview
Problem
The existing power grid systems face challenges in efficiently managing intermittent renewable energy sources, leading to curtailment of wind and solar power, which results in wasted energy and increased transmission and distribution costs.
Innovation Solution
A system comprising an energy storage unit and a flexible datacenter that can dynamically modulate power delivery based on monitored power system conditions or operational directives, utilizing behind-the-meter power sources to minimize grid interaction and reduce energy waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If curtailment is applied to reduce transmission congestion, then grid stability is improved, but renewable energy generation is reduced
Solution Approach 1:
The patent introduces a behind-the-meter electrical load as an intermediary component between the renewable energy generator and the grid. This load absorbs excess generated power locally, preventing transmission congestion while allowing the generator to maintain full output. The intermediary load acts as a buffer that decouples the generator from grid constraints, resolving the contradiction between maintaining grid stability and maximizing renewable energy production.
2Loss of energy
If behind-the-meter electrical load is added to absorb excess power, then energy waste is reduced, but device complexity increases
Solution Approach 1:
The behind-the-meter electrical load is designed with multi-functionality to reduce overall system complexity. It serves multiple purposes: absorbing excess power to prevent waste, providing voltage support, and enabling the generator to operate at full capacity regardless of grid conditions. By consolidating these functions into a single component, the patent avoids the need for multiple separate devices while still achieving energy conservation goals.
