Decentralized P2P Electricity Trading Model for Thailand.

Area of Science:

• Electrical Engineering
• Energy Systems
• Smart Grids

Background:

• Thailand's power system is undergoing a significant energy transition.
• Increased integration of renewable energy (RE) and the rise of prosumers are key drivers.
• Digitalization and local energy markets (LEM) are reshaping energy business models.

Purpose of the Study:

• To introduce a decentralized business model for electricity trading in Thailand's micro-grids.
• To propose a Hybrid P2P trading platform combining fully P2P and community-based trading.
• To validate the model's effectiveness in managing energy transition challenges.

Main Methods:

• Developed a Hybrid P2P trading model for micro-grids.
• Implemented a decentralized price mechanism using Auction Mechanism (AM), Bill Sharing (BS), and Traditional Mechanism (TM) for community-based trading.
• Validated the model through a case study with 75 consumers and 25 PV rooftop prosumers.

Main Results:

• The decentralized trading model significantly reduced community energy import and export during daytime.
• Hybrid P2P trading demonstrated superior performance compared to centralized approaches.
• Both community and individual levels benefited from the decentralized model.

Conclusions:

• Decentralized business models are effective for managing energy transitions in micro-grids.
• Hybrid P2P trading offers a viable solution for electricity exchange with prosumers.
• The proposed model enhances energy efficiency and economic benefits within local energy markets.
