1Object-affected harmful factors
If distributed renewable energy systems are used to reduce carbon emissions and pollution, then environmental sustainability is improved, but the ability to meet variable consumer demand deteriorates due to variable power output
Solution Approach 1:
The patent introduces a microgrid controller as an intermediary system that coordinates between renewable energy sources, energy storage devices, and consumers. The controller predicts power generation and consumption using time-series data, then optimizes energy distribution to ensure reliable supply while maintaining environmental benefits of renewable energy.
Solution Approach 2:
The system performs preliminary actions by predicting future power generation and consumption patterns using historical time-series data. This advance prediction allows the microgrid controller to proactively adjust energy storage charging/discharging schedules and distribute power before demand fluctuations occur, ensuring reliability without fossil fuel backup.
2Reliability
If conventional power plants with constant output generators are used to ensure power availability, then power supply reliability is improved, but energy waste increases due to inability to scale output
Solution Approach 1:
The patent implements dynamic power output adjustment by using energy storage devices that can rapidly charge and discharge to match varying consumer demand. The microgrid controller continuously adjusts the operating state of the system based on real-time predictions, enabling the renewable energy system to dynamically scale output without the energy waste associated with constant-output conventional generators.
3Device complexity
If microgrids are designed without precise methodologies to use off-the-shelf storage devices, then design complexity is reduced, but system stability and performance deteriorate
Solution Approach 1:
The patent changes the approach from selecting specific storage device models to selecting time-series data parameters for prediction models. The microgrid controller uses configurable prediction timeframes and optimization parameters that can be adjusted without changing hardware, allowing precise control of stability and performance while maintaining design simplicity through software-based customization.
