Abstract


In this paper analysis of ANN based active power filter performance for renewable power generation system has been proposed. A four leg VSC is used in this system, and this allows the reparation of current harmonic components, as well as unbalanced current generated by single-phase nonlinear loads. A new ANN controller has been proposed to improve the %THD in the non linear current. Generally the PI controller has more %THD; the ANN controller has more effect and will reduce the %THD. %THD table shows the differences between conventional controller and ANN controller. The simple numerical model of the active power filter, together with the effect of the equivalent power system impedance, is derived and used to design the analytical control algorithm. The simulation result shows the efficiency of the system using MATLAB/SIMULATION software. The reimbursement performance of the proposed active power filter and the associated control scheme with ANN controller have been tested under stable status and transitory operating environment through the simulation results.
