Case studies on multi-agent systems for microgrid control and optimization showing communication structure between layers in a multi-microgrid setup.

Proposed Multi layered multi agent Network for smart connected community within a Multi-Microgrid

Background:

In the case studies on multi-agent systems for microgrid control and optimization like power instability, intermittent load integration, and inefficient communication. These issues become more complex when multiple decentralized units must coordinate effectively. This blog explores case studies on multi-agent systems for microgrid control, showcasing how intelligent, multi-layered frameworks can solve these issues using real-time decision-making and energy optimization.

Solution:

In the case studies on multi-agent systems for microgrid control and optimization.Our research proposes an intelligent, multi-agent-based system (MAS) with advanced algorithms to optimize power, price, and comfort across hierarchical community microgrid structures:

1.Multi-Layered Control Framework for Microgrid Systems:

We present a hierarchical architecture for multi-microgrid (MMG) environments using home, local, and global controllers. This structure leverages multi-agent systems (MAS) to process real-time (RT) and day-ahead (DA) signals. As demonstrated in our case studies, this ensures seamless coordination between energy resources, consumers, and grid components.

2. Implementation of Intelligent Algorithms Based on Specific Scenarios

Algorithms like Prioritized Plug and Play (PPnP), Prioritized Particle Swarm Optimization (P-PSO), and Knapsack were used in Python and MATLAB (PADE framework). These were tested in simulated community setups. Each case study illustrates how MAS improves power dispatch, optimizes pricing models, and maintains comfort levels.

3. Smart Devices and Real-Time Signal Integration:

Smart thermostats and HVAC control systems were integrated into each test scenario. RT and DA signals were used to dynamically adjust performance based on consumer needs. The multi-agent system effectively ensured energy savings and consistent user satisfaction in each case study.

Results:

  • RES Integration: These results from the case studies on multi-agent systems for microgrid control and optimization show that  Renewable energy generation improved by 1.4% in Case 2 and 1.9% in Case 3, illustrating the benefits of renewable integration in community microgrids.
  • Cost and Comfort Balance: Cost and Comfort Balance: High-income households experienced minimal price increases (1.0064% in Case 2, 1.1154% in Case 3) while maintaining optimal comfort levels, demonstrating the system's ability to balance cost-efficiency with user satisfaction.
  • Efficiency Gains: Power dispatch efficiency improved by 1.2564% in Case 2 and 1.7939% in Case 3, compared to the baseline, showcasing the optimization potential of multi-agent systems for microgrid control.
  • Practical Scenarios: Our case studies demonstrated the effectiveness of the MAS approach in addressing community microgrid challenges, including energy optimization and user comfort.

Energy management in microgrids is a growing field. For instance, Renewable Energy World discusses the importance of renewable integration in modern microgrids, noting that improvements in optimization can increase energy efficiency.
