摘要
建立合理、有效的微电网电力市场交易机制来激励分布式清洁能源并网,是实现微电网运营多方共赢、经济环保的重要途径。针对微电网交易环境中的现有问题,提出了基于区块链技术的电力交易模式以改进微电网电力市场。介绍了微电网电力交易模式及其数学模型,以量化区块链技术对交易主体决策的影响。由于系统内部主体存在产权独立性,且市场中电价、电量竞标存在先后行动次序,应用Stackelberg博弈理论求解市场各主体在追求目标最优时电价和电量的交互策略。仿真结果表明:微电网基于区块链技术整合利用了分布式资源和设备,促进能源结构清洁化转型;供需双方都作为独立节点参与电力市场,区块链交易平台信息的公开透明提高了参与主体用电决策的精准性和经济效益。
Establishing a reasonable and effective trading mechanism for microgrid electricity market to encourage the integration of distributed clean energy is an important way to achieve the multi-party win-win,economy and environmental protection in microgrid operation.In view of the existing problems in the microgrid trading environment,a power trading mode based on the blockchain technology is proposed to improve the microgrid electricity market.The microgrid power trading mode and its mathematical model are introduced to quantify the impact of blockchain technology on the decision-making of trading entities.Due to the independence of property rights of the system internal entities,and the existing order of action in the electricity price and power bidding in the market,the Stackelberg game theory is used to solve the interactive strategy of electricity price and power when the market entities pursue the optimal target.The simulation results show that the microgrid integrates and utilizes distributed resources and equipment based on blockchain technology to promote the clean transformation of the energy structure,both the supply and demand parties participate in the electricity market as independent nodes,and the open and transparent information of the blockchain trading platform improves the accuracy and economic benefits of the electricity decision-making by the participating entities.
