基于信号同源的AGC负荷解耦控制和自动寻优研究

Research and Application of AGC Load Decoupling Control and Automatic Optimization Based on Signal Homology

近年来风电、光伏等新能源发展迅速,因新能源随机性强、波动性大,给电网的安全稳定运行带来了挑战。目前我国能源结构中火力发电仍占据主导地位,大型火电机组承担了吸收这些不稳定电力因素,提升火电机组的快速变负荷能力,成为解决新能源规模化并网难题的有效途径。电网调度要求火电机组负荷具备更宽的调节范围和更快速的响应速率,对火电机组的负荷响应性能提出了更高的要求,因此统筹解决大型火电机组的负荷响应以及优化技术具有重要意义。

In recent years,wind power,photo-voltaic and other new energy sources have developed rapidly.Because of the randomness and volatility of new energy sources,they pose challenges to the safe and stable operation of the power grid.At present,thermal power generation still occupies a dominant position in China’s energy structure.Large-scale thermal power units have undertaken to absorb these unstable power factors and improve the capability of thermal power units to respond the rapid variable load,which has become an effective way to solve the problem of large-scale grid connection of new energy.The load response performance puts forward higher requirements,so it is of great significance to co-ordinate the load response,climbing ability and optimization technology of large thermal power units.
