| 摘要: |
| 当前大规模波动性风电接入给电网安全、有功调度和无功电压控制带来严重挑战，传统能量管理系统（EMS）的集中式架构在网络建模、信息通信、分析的快速性以及控制的敏捷性方面均难以适应抑制风电快速波动的要求。为此，提出了分布集中式EMS框架下的风电场分布式EMS的体系结构，详细阐述了其关键技术，含：风电场网络建模及全状态感知、风功率预测、状态监视、安全分析和自动发电/电压控制等。通过一个风电场EMS自动电压控制的应用实例说明风电场分布式EMS的运行效果。 |

| Abstract: |
| To integrate large-scale intermittent wind power greatly challenges the power system operation on security analysis, active power dispatch and voltage control. The conventional centralized architecture of energy management system (EMS) could not satisfy the requirement to mitigate the wind power’s fluctuations, especially on network modeling, information communication, real-time analysis and flexible control. As part of a new distributed-centralized architecture, a distributed EMS for wind farm is proposed, as well as the key technologies that include network modelling of wind farm grid, state estimation, wind power forecasting, 3-D monitoring, security assessment, AGC and AVC, etc. An application example of wind farm voltage control is presented to illustrate the operation effects of the distributed EMS. |
