【摘要】：结合我国电网近年来运行实践,对复杂互联电网特性进行了深入分析,概括当前电网主要特点,包括:故障影响呈现全局化、电网调节能力不断下降、电网抗扰动能力持续恶化、电力系统稳定形态更加复杂。对电网支撑可再生能源发展面临形势与存在问题进行了深入思考,包括关于未来电力系统构建、提升大电网仿真能力、优化系统运行控制策略和技术支撑手段、研究解决电力电子装置大规模并网引发的新稳定问题。文章旨在为新能源高比例接入情况下电力系统运行、分析、控制等研究提供思路和方向。
[Abstract]:Combined with the operation practice of China's power grid in recent years, the characteristics of complex interconnected power network are analyzed in depth, and the main characteristics of the current power grid are summarized, including: the global effect of the fault, the decline of the power grid regulation capacity.The stability of power system becomes more complex because of the deterioration of power network anti-disturbance ability.The situation and existing problems in the development of grid supporting renewable energy are deeply considered, including the construction of power system in the future, the enhancement of power network simulation ability, the optimization of system operation control strategy and technical support means.To solve the new stability problem caused by large-scale grid-connected power electronic devices.The purpose of this paper is to provide ideas and directions for the study of power system operation, analysis and control under the condition of high proportion access to new energy sources.
