Hybrid Energy Storage System for Renewable Power Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The variability in renewable energy sources, such as wind and solar, leads to unstable energy output, which does not align with the consistent energy demand, and the limitations of fossil fuel-based energy generation, including environmental concerns and price volatility, necessitate a system to stabilize energy supply.
Innovation Solution
A hybrid energy storage system that integrates multiple energy storage devices, such as batteries and flywheels, with an energy flow controller that senses and controls energy distribution from renewable and non-renewable sources to maintain a stable power output, using adaptive control techniques to select and utilize the most suitable energy storage devices based on capacity, duration, and intake rate thresholds.

Engineering Contradiction Analysis
1Object-affected harmful factors
If renewable energy sources (wind, solar) are used to generate electrical energy, then environmental pollution is reduced and sustainability is improved, but energy output becomes unstable and variable
Solution Approach 1:
The patent combines multiple energy storage devices with different characteristics (batteries for energy storage and flywheels for power stabilization) into a hybrid system. This merging allows the system to simultaneously address environmental concerns by using renewable sources while compensating for their instability through the complementary strengths of different storage technologies.
Solution Approach 2:
The hybrid energy storage system acts as a composite structure combining different energy storage technologies. Each technology contributes its unique properties: batteries provide high energy density for sustained storage, while flywheels provide high power density for rapid response. The composite system achieves stability that individual components cannot provide alone.
2Stability of the object's composition
If fossil fuel-based energy generation is used, then stable energy supply is maintained, but environmental pollution increases and operating costs become volatile
Solution Approach 1:
The hybrid energy storage system serves as an intermediary between renewable energy sources and the electrical load. It decouples the variable output of renewable sources from the steady demand of loads, allowing fossil fuel plants to be reduced or eliminated while maintaining supply stability. The storage system mediates the mismatch between intermittent generation and constant demand.
3Device complexity
If a single type of energy storage device is used, then system complexity is reduced, but the ability to stabilize energy output under varying conditions is limited
Solution Approach 1:
The system dynamically selects and switches between different energy storage devices based on real-time conditions. The control system monitors state of charge, power requirements, and device availability to optimally allocate energy flows. This dynamic operation allows the system to adapt to varying conditions while managing complexity through intelligent control rather than static design.
Solution Approach 2:
The hybrid energy storage system segments the energy stabilization function into distinct components: batteries handle energy time-shifting and flywheels handle power smoothing. This segmentation allows each component to specialize in its optimal function while the control system coordinates them. The segmentation manages complexity by dividing the overall stabilization task into manageable sub-functions.

AI summary
This disclosure generally relates to stabilizing energy provided by an energy source, and more particularly to systems and methods for using multiple types of energy storage devices to selectively capture and provide energy. An energy source provides energy, and the energy storage devices selectively capture energy provided by the energy source in excess of an immediate energy requirement of a load and selectively provide energy when the immediate energy requirement of the load exceeds the energy provided by the energy source.
