Power Filter

As the share of renewable energy sources (RES) in distribution grids increases, several power quality challenges arise. Due to its intermittent nature, RES lead to voltage and frequency fluctuations in the grid that affect power quality. Moreover, as RES are connected via power converters, there is also a higher harmonic distortion pollution introduced by the switching power electronics involved, (Liang, 2017). A proven solution is the implementation of Active Power Filters (APF), which are able to compensate the unbalanced, harmonic, and reactive components of a load under different supply conditions. In order to achieve the desired compensation characteristics, the selection of an appropriate control strategy is critical, (Kumar & Mishra, 2016). Classic APF control strategies achieve said goals, although with struggles under changing load scenarios with limitations on their operational modes, (Weihe, Cateriano Yáñez, Pangalos, & Lichtenberg, 2018).This paper proposes the use of an advanced model-based control method, i.e. Model Predictive Control (MPC), to improve the performance of APF devices. Model-based control methods allow for better performance when the model of the plant is known before hand or through measurements, the MPC extends this further by introducing a cost function that ensures optimal operation even under constraints, (Maciejowski, 2002). References Kumar, P., & Mishra, M.

The Impact

This paper presents the simulation-based study and results of a three-phase shunt active power filter (SAPF) for power quality improvement. The power quality of the power systems is degraded because of the presence of non-linear loads at the consumer end. The SAPF can reduce the impact of harmonics caused by the non-linear loads. The analyzed SAPF system is modeled and simulated using MATLAB-Simulink workspace. The ultimate goal of this study is to improve the total harmonic distortion of the system as per the standards defined by IEEE-519.

ABSTRACT:  According to development of power electronics device, harmonic distortion spread on the network. Thus harmonic is a threat for instrument, network, decreasing of line capacity and etc. Active power filter (APF) can be employed for harmonic compensation in power systems. In this paper a distorted distribution feeder is considered and analyzed from power quality viewpoint using power analyzer device and simulated in MATLAB-Mfile. Then the size and place of active power filters are determined by use of Biogeography Based Optimization (BBO). The goal of this optimization is minimizing of losses and total harmonic distortion (THD) in feeder by considering economical cost.  The performance of the approaches are assessed and appreciated by a case study on the Ghaemshahr-Iran Distribution network. Measurement is done on the city network by power analyzer CA8310. All data was collected on Computer. Then researcher algorithm BBO, it is selected the best place and size for Active power filter. The results show a good performance.

Hybrid Renewable Energy System

Increased usage of combined PV-Wind renewable energy sources is seen as a positive step toward reducing air pollution and carbon emissions. However, since non-linear loads have increased dramatically, voltage quality and harmonic distortion concerns have arisen, affecting the operation of combined PV-Wind RES and smart-grid electrical transmission structures. This study shows how a Shunt active power filter may improve energy quality in a microgrid structure at the distribution level. The major goal of this article is to find an appropriate controller approach for improving the shunt active power filter's compensating capacity. This paper simulates a PV-Wind hybrid renewable energy system that operates in the presence of unpredictably variable solar and wind energy resources. The objective is to allow the construction of an electrical control structure that produces the right duty cycle. It will aid in the regulation and stabilization of voltages at dc/dc energy conversion plant. Simulation is used to assess the proposed control system's ability to enhance power quality. The device's compensating capability is mostly determined by the DC link capacitor voltage control. The closed loop functioning of a proportional integral controller is used to attain this voltage regulation in the past. To increase the functioning of a shunt active power filter, the MOPSO procedure approach has been presented. The performance of suggested approaches and the comparison of different pulse generating strategies have been validated in the SIMULINK/MATLAB model environment. The suggested technology successfully improves power quality on the grid and maintains a steady voltage on the grid despite variations in RE output and load.

With the modernization of loads using power electronic components and dynamic loads diminishes the power quality of the system. Integration of renewable energy sources is the best solution to meet the additional power demand and also to improve the power quality problems like low power factor and harmonics distortions. In this paper, an adaptive dynamic shunt active power filter is proposed to alleviate the power quality problems like current harmonic distortions and reactive power compensation. The proposed control strategy performance is examined under different source voltage conditions under IEEE standards. Photovoltaic system is integrated at DC link of the Adaptive dynamic shunt active power filter. Proposed system performance is studied by using MATLAB/SIMULINK Environment.
