Solution Overview
Problem
Existing microgrids do not account for individual consumption habits, leading to inefficiencies in power distribution and increased reliance on fossil fuels, resulting in potential power outages and high energy costs.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If energy sources and storage means are shared in existing microgrids, then power distribution is simplified, but individual consumption optimization is lost and fossil fuel consumption increases
Solution Approach 1:
The system segments the microgrid into individual building-level energy management units, each with its own domestic module that independently calculates and optimizes energy distribution based on local consumption patterns. This segmentation allows each building to optimize its energy usage without being constrained by centralized sharing arrangements, thereby reducing overall fossil fuel consumption while maintaining system simplicity through modular architecture.
2Device complexity
If centralized power distribution is used, then infrastructure is simplified, but individual building energy optimization is prevented
Solution Approach 1:
The system implements dynamic energy distribution by enabling real-time calculation and adjustment of energy flows at each building level. The domestic modules continuously monitor consumption patterns and dynamically optimize power distribution based on current needs, allowing the system to adapt to changing conditions while maintaining a relatively simple centralized infrastructure through the local network and public network connections.
3Reliability
If fossil fuel generators are used to avoid power outages, then power supply reliability is improved, but energy costs and environmental impact increase
Solution Approach 1:
The system employs feedback mechanisms where domestic modules continuously monitor power availability, consumption patterns, and battery status. This feedback enables the system to proactively manage energy resources, optimize the use of renewable energy and battery storage, and only resort to fossil fuel generators when absolutely necessary, thereby maintaining power supply reliability while minimizing energy costs and environmental impact.
4Productivity
If individual building energy management is implemented, then energy optimization is improved, but system complexity increases
Solution Approach 1:
The system introduces a local network as an intermediary layer between individual building management systems and the public network. This intermediary facilitates coordinated energy management across multiple buildings, allowing individual buildings to optimize their energy usage while sharing resources and information through the local network, thereby achieving energy optimization without proportionally increasing overall system complexity.

AI summary
A system for managing the distribution of electrical power between at least two distinct buildings each comprising a domestic network connected to a local network is provided, said local network being connected to a public network. Each building comprises a power source, an inverter connected to said power source, a battery supplied with power by the inverter, and at least one apparatus operating using the power from the domestic network. The system comprises, in each building, a domestic module for regulating the power flow through the domestic network. The system comprises a central module connected to each domestic module making it possible to regulate the power flow between the local network and the public network, said central module being arranged so as to regulate the power flow between the buildings in order to allow an exchange of power between a domestic network in excess and a domestic network in deficit.
