Difference between requirements for reactive power in a traditional and a restructured power system using monte carlo method

Due to importance of requirements of reactive power in a power system, by using probabilistic load flow with Monte Carlo method we can gain the exact value of requirement reactive power of system in a traditional and a restructured power system. In this paper the main object is the examination of effect of random changes in load, generation and price on all requirement reactive power of system and also the amount of reactive power of each bus. Effective parameters in reactive power distribution are determined and an effective probable model for each of parameters is presented. The simulation results are used by network management for reactive power and voltage control service contracts.The results of analysis in two environment (traditional and restructured power system ) are shown. In order to arrive to the aim, Monte Carlo method that is quite practical and useful method for engineering problems, and MATLAB software is used, and studies are done on 30 buses IEEE system that is modeled by MATPOWER software.
