基于数字人民币的智能电表及实时电力交易新模式

Real-time power trading mode based on an e-CNY smart electricity meter

综述分析了现有智能电表及电力交易机制无法真正地实现实时交易-实时结算是限制实时电价电力交易模式的关键因素。以实现电能的实时计量-实时交易-实时结算为目标,依托数字人民币的支付即结算和可编程特性,构建了硬件上由计量芯、管理芯及交易芯构成,软件上基于GlobalPlatform可信框架,内置数字人民币硬件钱包的e-CNY智能电表结构。构思了基于实时电价、销售和上网电价智能合约实时发布、实时结算的发电侧和售电侧实时电力交易新模式。所提出的e-CNY智能电表及实时电力交易新模式可有效激励发电企业及用电方通过跟踪价格信号来响应系统需求,积极参与电网调峰、节能减碳,助力“3060双碳”目标的达成。

This paper summarizes and analyzes the fact that existing smart meters and electricity trading mechanisms cannot truly realize real-time power trading,and real-time settlement is the key factor restricting the real-time electricity price and electricity trading mode.By taking the goal of realizing real-time measurement,real-time trading,and real-time settlement of electricity and also relying on the payment settlement and programmable features of e-CNY,an e-CNY smart electricity meter with an e-CNY wallet built-in is designed.Its hardware is composed of a metering core,management core and transaction core and its software is based on the GlobalPlatform trusted framework.A new mode of real-time power trading on both the power generation and sales sides is conceived.It is based on real-time electricity prices,real-time released smart price contracts of power generation and sale,and real-time settlement.The e-CNY smart meter and the new real-time power trading model proposed can effectively encourage power generation companies and power users to respond to power system commands by tracking price signals,to actively participate in grid peak shaving,energy conservation and carbon reduction,and contribute to achieving the“3060 carbon peak and neutrality goals”.
