Microgrid Load Prioritization for Reliable Renewable Energy Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Renewable microgrids face challenges in managing electrical energy effectively due to the intermittent nature of renewable power sources, lacking the capability to meet consumer demand without supplemental energy sources and efficient load management.
Innovation Solution
A system comprising computer processors configured to store priorities for consumer loads, forecast energy availability from renewable and energy storage systems, and allocate energy based on priority, directing energy from these systems to consumer loads to ensure reliable energy distribution without the need for supplemental sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If renewable microgrids use supplemental energy sources (fossil fuel generators or grid connections) to ensure reliability, then the reliability of energy supply is improved, but the cost and complexity of the system increases
Solution Approach 1:
The patent extracts the need for supplemental energy sources by implementing a priority-based load management system that curtails non-essential loads when renewable energy is insufficient. Instead of adding fossil fuel generators or grid connections, the system removes the requirement for these supplements by intelligently managing demand side, thereby maintaining reliability while avoiding the complexity and cost of additional generation infrastructure.
Solution Approach 2:
The microgrid system performs self-service through automated priority-based load management. When renewable energy generation is insufficient, the system automatically identifies and curtails lower-priority loads without external intervention or supplemental sources. This self-managed demand response mechanism ensures energy supply reliability while avoiding the need for complex supplemental generation infrastructure.
2Loss of energy
If renewable microgrids implement load management to match consumer demand with available energy, then the need for supplemental energy sources is reduced, but the system complexity and difficulty of implementation increases
Solution Approach 1:
The patent segments consumer loads into different priority categories (critical, essential, non-essential) and manages each segment differently. This segmentation allows the system to implement load management by simply controlling which segment receives power during shortages, rather than implementing complex real-time optimization across all loads. The segmentation approach reduces energy waste while keeping the management system relatively simple and易于 implementation.
3Ease of manufacture
If all-renewable islanded microgrids are implemented without supplemental sources, then the cost and environmental impact is reduced, but the reliability and ability to meet consumer demand deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-establishing priority classifications for different consumer loads before energy shortages occur. This preliminary categorization enables the system to quickly and effectively manage demand during shortages without complex real-time decisions. By preparing the load management framework in advance, the system achieves reliable energy supply at lower cost, as it can curtail appropriate loads automatically when renewable generation is insufficient, without needing expensive supplemental sources.

AI summary
The present disclosure provides systems and methods for managing electrical energy generated by a renewable microgrid. One or more processors of a system may store priorities for one or more consumer loads; forecast an amount of available electrical energy for a time period; allocate a first electrical energy amount to a first consumer load to a first energy limit for the time period; determine more electrical energy is forecast to be available from the RES or the ESS for the time period; identify a second consumer load of the one or more consumer loads; allocate a second electrical energy amount to the second consumer load for the time period; and direct electrical energy from the RES or the ESS to the first and second consumer loads according to the allocations.
