摘要：

本文提出了自能源(we-energy, WE)这一新的能源互联网基本能源单元,为新能源就地消纳、各类分布式电源的即插即用和产–消–储一体化的多能互补提供了一种能源管理策略.为处理自能源在不同运行条件下的多能协调控制与优化问题,建立了基于信息–物理–能源–经济系统(information-equipment-energy-economical system, IEEES)的四元模型,提出了自能源的4种运行模式.该模型利用自能源中信息、物理、能源和经济4个子系统的耦合特性,根据能源互联网运行态势进行模式转化,建立了对应的自能源状态方程,并进行了自能源分布优化、协同控制等典型应用场景的分析.通过经济优化,获取了多个自能源在市场交易中的最优策略,实现了自能源内部能源的合理分配.通过对自能源内部设备的协同控制,实现了在功率波动情况下并网点系统参数及能源交换的稳定.
