Real-time simulation on a multi-core PC platform for model-based power system harmonic study

It is typically time-consuming to obtain the time-domain responses of power system from conventional off-line simulation. With the advanced development in computer technologies, the applications of real-time simulations are introduced to power system studies for enhancing the capabilities of traditional off-line simulations. This paper presents a PC cluster-based real-time parallel simulator developed on a multi-core PC platform which is capable of speed up the execution time of simulation while the solution accuracy is maintained. A numerical example, five-bus power network, performed on MATLAB/SIMULINK is offered to illustrate the effectiveness of the used simulator.
