Networked Renewable Power Plants for Stable Load Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Renewable energy power plants (REPPs) face challenges in providing consistent and reliable power due to intermittent output, which is incompatible with real-time load and grid balancing requirements, necessitating more reliable power delivery.
Innovation Solution
A method and system that combine the power outputs of multiple REPPs with varying output capabilities to achieve a combined output with lower variability, allowing for more consistent and reliable power delivery to loads, utilizing a controller to allocate and direct the combined power output to specific loads via a grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual REPPs operate independently, then each plant can be sized to meet specific load requirements, but the power output variability remains high and reliability is insufficient
Solution Approach 1:
The patent combines multiple independent REPPs into a networked system where their power outputs are aggregated and coordinated. By merging the capabilities of multiple plants with varying output characteristics, the system achieves higher overall reliability while managing complexity through centralized control algorithms that optimize power allocation across the network.
2Stability of the object's composition
If REPPs are networked together, then power output variability is reduced and reliability improves, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the control system continuously monitors power output from each REPP and adjusts allocation decisions in real-time. This feedback loop enables the system to maintain stable power delivery by dynamically responding to variations in individual plant outputs, thereby achieving stability without requiring overly complex predetermined control schemes.
Solution Approach 2:
The control system employs dynamic power allocation strategies that adapt to changing conditions in the networked REPPs. Rather than using fixed allocation rules, the system dynamically adjusts power distribution based on real-time output capabilities of each plant and current load requirements, enabling stability maintenance with adaptable rather than rigid control mechanisms.
3Reliability
If excess capacity is built into individual REPPs to ensure reliable power delivery, then reliability improves, but construction and operation costs increase
Solution Approach 1:
By merging multiple REPPs into a networked system, the patent eliminates the need for each individual plant to have excess capacity built in. The combined output of multiple plants with varying generation patterns provides the reliability buffer that would otherwise require expensive excess capacity in single plants, thereby reducing total quantity of generation resources needed while maintaining or improving reliability.

AI summary
A method described delivers power to a first load and a second load from networked power plants. The method may include receiving a power delivery profile for the first load, receiving a power delivery profile for a second load, determining a power output capability of a first renewable energy power plant (REPP), and determining a power output capability of a second REPP. The method may also include setting a power output for the first REPP and a power output for the second REPP based on the power delivery profile for the first and second loads and the power output capabilities of the first and second REPPs. The method may also include allocating a combined power output of the first and second REPPs to the first and second loads and delivering the allocated combined power output to the first and second loads.
