Research On Stability Predictive Control Of Power System Based On WAMS

The influence of China’s economic and social development,the power system has developed very rapidly,so the power system there are many methods of predictive control,and with the wide area measurement system and the implementation of popular,stable control how efficient into the electricity sector,the main research direction,this article on the relevant predictive control the problem of inquiry.First of all,this paper introduces the related concepts of wide area measurement system and predictive control,analyzed the method of predictive control of power system,introduces the generalized predictive control technology in the application and effect of unit length of M time domain and explore value on the stability and sensitivity of power system.Then,the simulation model is set up in MATLAB to analyze the result.Finally,the seven node model selection by using the simulation software PSASP,calculated voltage stability,respectively in various components of input parameters,and the system of regulation,the system voltage stability criterion.The simulation results are analyzed and the following conclusions are obtained.When the load reaches the maximum value,the high voltage value coincides with the low voltage,and the derivative between P and V is zero.This is the judgment of voltage stability.
