新型电力系统不确定性显著增强,自动发电控制(AGC)系统面临新挑战。首先,系统梳理了AGC系统架构和运行机制,分析了调节需求、调节资源和控制环节中三重不确定性的来源,并梳理了现有针对不确定性研究的局限性。然后,深入剖析了调节需求在平稳波动、斜坡变化与阶跃扰动多模态耦合下的非高斯随机分布特征,阐明了新能源等调节资源响应不确定性增强,以及控制环节中指令可靠性、传输时延和响应惯性不确定性加剧等的具体表现和影响。最后,结合已有应对措施的不足,从攻克面向非高斯随机扰动的新型控制理论、建立针对资源响应不确定性的精准量化评估方法、强化适应新型资源接入的安全防误技术和构建融合AGC系统的高保真验证平台4个方面,探讨了未来需进一步深入研究的重点方向。
Uncertainties in new power systems increase significantly
bringing new challenges to the automatic generation control (AGC) system. First
this paper systematically sorts out the architecture and operating mechanism of the AGC system
analyzes the sources of triple uncertainties existing in regulation demand
regulation resources and control links
and summarizes the limitations of existing research on uncertainties. Then
this paper thoroughly analyzes the non-Gaussian stochastic distribution characteristics of regulation demand under the multimodal coupling of steady fluctuations
ramp variations and step disturbances
and illustrates the specific manifestations and influences of rising response uncertainties of regulation resources including renewable energy
together with aggravated uncertainties of command reliability
transmission delay and response inertia in control links. Finally
combining the deficiencies of existing countermeasures
this paper discusses the key directions worthy of in-depth follow-up research from four perspectives
i.e.
developing novel control theories targeting non-Gaussian stochastic disturbances
establishing accurate quantitative evaluation methods for resource response uncertainties
strengthening safety and error prevention technologies suitable for new-type resource grid integration
and building high-fidelity verification platforms integrated with the AGC system.
