为适应智能电网能量管理系统(energy management system,EMS)从集中式走向分散式的发展趋势,建立了一种分散自治的自动发电控制(automatic generation control,AGC)功率分配框架。把传统区域电网分成若干个领地电网,结合了多智能体一致性协同理论,分别以调节费用和爬升时间为一致性状态变量,提出基于虚拟发电部落一致性的功率动态分配方法。标准两区域模型仿真表明,虚拟发电部落协同一致性方法能有效解决未来智能电网AGC功率分配的分散自治问题。
To adapt the trend in development of energy management system (EMS) from centralized to decentralized, a decentralized and autonomous framework of automatic generation control (AGC) for generation dispatch was constructed. The area power grid was divided into several territory grids, and by selecting the regulation cost of each territory and ramp time of each unit as the consensus variables respectively, the virtual generation tribe (VGT) based consensus algorithm for dynamic generation dispatch was proposed. Simulation of the two-area load frequency control model shows that the consensus algorithm based VGT can effectively solve the decentralized autonomous problem of generation command dispatch for future AGC in smart grid.
