摘要:Renewable generation affects power quality due to its nonlinearity, since solar generation plants and wind powergenerators must be connected to the grid through high-power static PWM converters. This paper presents active power filterimplemented with a four-leg voltage-source inverter. A Novel predictive control scheme is implemented to control the inverter.The main features of this control sceme is 1) To predict the future behavior of the variables to be controlled. The controller usesthis information to select the optimum switching state that will be applied to the power converter. 2) To control power converter toinject power generated from RES to the grid, and 2)To act as a shunt APF to compensate current unbalance, load currentharmonics, load reactive power demand and load neutral current The compensation performance of the proposed active powerfilter and the associated control scheme under steady state and transient operating conditions is demonstrated through simulationsresults.
