Trusted Metering Terminal and Application Design for Distributed Power Supply

This chapter delves into the design and implementation of a trusted metering terminal tailored for distributed power supply systems, with a particular emphasis on renewable energy sources like wind and photovoltaic power. The terminal is designed to ensure reliable and secure measurement of power generation, which is crucial for settlements between power suppliers and consumers. The chapter explores the integration of blockchain technology to enhance data security and reliability, addressing issues such as measurement accuracy and privacy disclosure. It also discusses the modular architecture of the terminal, which includes metering, management, blockchain, and communication modules. The design aims to be low-cost, lightweight, high-efficiency, and low-power, making it suitable for widespread adoption. The chapter provides detailed test results that validate the terminal's performance in terms of voltage and current accuracy, as well as blockchain functionality. Additionally, it outlines practical applications of the trusted metering terminal in scenarios such as distributed source self-provisioning allowance and grid access, and participation in the power market. The conclusion highlights the terminal's role in supporting the efficient use of distributed power supply and contributing to the rapid development of clean energy.
