### Theme
- energy trading in the network of Microgrid clusters
### Backound
- Introduction: **Distributed generation** refers to the configuration of smaller generating units close to energy sources (such as wind energy and solar energy) to meet the needs of specific users. In a **Microgrid**, each agent can be a buyer or a seller. The seller can sell the electricity from distributed generation to the buyer with demand.
- Advantages of Microgrid:
- **Reliability**. Microgrid can be connected or disconnected from main grid. When the main power grid is cut off, the Microgrid can rely on distributed generation and energy trading to maintain its operation.
- **Profitability**. For sellers, they can gain profits by selling excess energy to buyers. For buyers, they can buy energy at a lower price than the main grid.
- **Greenness** . For remote areas, traditional power distribution needs to span a long distance, which will waste a lot of energy. Because the geographical distance between generators and users in Microgrid is very close, the energy loss is very small.
### Problem description
- What I'm considering now is that when there is a **mismatch between supply and demand** in the Microgrid, trade between Microgrid and Microgrid will benefit participants more.
- In order to complete the transaction between Microgrids, I think each Microgrid should **elect a leader node**, which can collect information about the energy needed or sold by the whole Microgrid.When there is a problem in the leader node, a new leader node will be automatically elected in the microgrid to prevent single point of failure.
- When trading within the Microgrid, we can consider the establishment of a reputation system to encourage good behavior of agents and prevent malicious agents from damaging the system. I think the trade between Microgrids can also be used to build a **reputation system** to prevent malicious attacks.Considering the energy waste in the distribution process, the closer microgrid should get a higher score in the **score function** of reputation system, so as to encourage the microgrid not to trade with the Microgrid with too far **distance**.
