“…The state vector for the PI controller and the UDE-based controller is the same in this article, depending on the LCCL filter. Therefore, it is possible to develop the UDE-based controller for the LCCL type inverter [7] [20][21][22][23][24][25]. In this article, a control strategy of the inverter connected to the network with a LCCL filter centered UCC, whose topology of the inverter is identical to that of [3], is introduced, except that a category of resistance of passive amortization is included.…”

The LCL filter is commonly used as a grid-to-grid interface. Nonetheless, due to the features of LCL filter and process uncertainties, designing a controller with proper parameters is complex. In this paper, with the LCCL filter, the order of the inverter control system can be reduced to first order from third order and a strategy for controlling the inverter connected to the grid based on uncertainty and disturbance estimator is proposed with LCCL filter. The main objective of this paper is to upgrade the efficiency of grid-connected PV inverters with proposed LCL filter.

“…They can be considered as current sources that injectcurrents similar to identified harmonic currents at the network level. A PAPF can beofcurrent source structure type or voltagesource structure type, depending on the type of energy storage type, that achieved by an inductor or a capacitor [6]. The Figure 1 presents the two -level three-phase shunt active power filter connected to balanced power grid (vsi for i = {1, 2, 3}) powering a three phase parallel-connected two diode rectifiers feeding variable series (R, L) loads.…”

“…The feedforward or MLP networks have shown to be useful in replacing the HB controller to generate the IGBTs trigger signals [8,9,17,26,27]. Some authors have applied the MLP [28][29][30] to replace the extended PI control [31] of the DC side capacitor voltage, Vdc, of power converters.…”

Nonlinear Loads Compensation Using a Shunt Active Power Filter Controlled by Feedforward Neural Networks

The shunt active power filter (SAPF) is a widely used tool for compensation of disturbances in three-phase electric power systems. A high number of control methods have been successfully developed, including strategies based on artificial neural networks. However, the typical feedforward neural network, the multilayer perceptron, which has provided effective solutions to many nonlinear problems, has not yet been employed with satisfactory performance in the implementation of the SAPF control for obtaining the reference currents. In order to prove the capabilities of this simple neural topology, this work describes a suitable strategy of use, based on the accurate estimation of the Fourier coefficients corresponding to the fundamental harmonic of any distorted voltage or current. An effective training method has been developed, consisting of the use of many distorted patterns. The new generation procedure uses random combinations of multiple harmonics, including the possible nominal frequency deviations occurring in real power systems. The design of the generation of reference signals through computations based on the Fourier coefficients is presented. The objectives were the harmonic mitigation and power factor correction. Practical cases were tested through simulation and also by using an experimental platform, showing the feasibility of the proposal.
