| 摘要: |
| 从共享经济的角度出发，提出一种基于区块链技术的去中心化的车辆到电网(V2G)新模式。利用区块链技术和V2G技术天然的互补性，挂网的电动汽车以合理的价格将多余的电量包装成期货商品，通过点对点技术将售电信息扩散到整个网络；同时，需要紧急充电的电动汽车购买充电期间最低价位的期货商品并达成临时合约，待电网对其进行安全校验后正式达成交易，并以智能合约的形式存储电力交易信息，到期时完成价值的自行转移，实现电动汽车电力市场交易双方自行匹配、双边交易直接达成的目的。基于此，建立可行的交易理论模型。基于2个社区共150辆电动汽车的仿真分析验证了所提交易模式的经济性和可行性。 |

| Abstract: |
| From the perspective of sharing economy, a new decentralized V2G(Vehicle-to-Grid) mode based on blockchain technology is proposed. Taking advantage of the natural complementarity between blockchain technology and V2G technology, the electric vehicles connected to the network package the surplus electricity into futures goods with reasonable price, and spread the electricity sales information to the whole network through point-to-point technology. Meanwhile, the electric vehicles that need emergency charging buy the futures goods with the lowest price during the charging period and reach temporary contracts, the transactions will be formally reached after the security check of power grid, the power transaction information is stored in the form of smart contract, and the value is transferred automatically when it is due, which realizes the purpose of self-matching and direct bilateral transaction between the two parties in the electricity market of electric vehicles. On this basis, a feasible transaction theoretical model is built. The simulation and analysis based on 150 electric vehicles in two communities verify the economy and feasibility of the proposed transaction strategy. |
