Performance Improving Of Active Power Filter In Microgrid System By Using Fuzzy Controller
Shaila Chhatrabhuj Jadkar,  Varsha Jain
In the distribution system load has been sudden changes and it is like a non-linear loads the use of nonlinear loads creates the problems in the power system such as load harmonics, reactive power and excessive neutral currents. This paper presents an Active Power Filter implemented with a four leg voltage source inverter using dq (synchronous reference frame) based current reference generator scheme is presented. the use of a four-leg voltage source inverter allows the compensation of current harmonic components and also unbalanced current generated by single phase non-linear loads. the grid interfacing can thus be utilized as i)power converter to inject generated power from rest of the grid, and ii)shunts APF to current unbalance, load current harmonics and load reactive power demand the compensation, performance of the active power filter using an fuzzy controller and the associated control scheme under steady state and transient operating condition is demonstrated through simulation results.
Keywords- Active power filter, Four leg converter, fuzzy controller, RES(renewable energy sources).
