考虑电-气-碳综合交易的跨国电网分散式电力调度—以规划的东北亚跨国电网为例 [PDF]
全球能源互联网, 2019 为了实现跨国电网的有序发展与协调运行，跨国层面的电力交易、天然气交易和碳交易的有机结合十分关键。为此，以电力系统为核心，考虑天然气交易与碳交易的相关耦合因素，建立了跨国电-气-碳综合交易模型。在上述综合交易的框架下，建立了跨国电网的动态电力调度模型，以实现全局效益的最大化。进一步地，为了保护各个国家的工业信息隐私，提出了分散式的跨国电力调度算法，将全局优化问题转化为各个国家的子问题迭代求解，得到满足给定精度的全局最优解。最后，对东北亚跨国电网仿真算例进行测试，分析讨论在不同电-气 ...
