  Applying distributed energy resources (DERs) to power systems has been promoted as a promising option to meet the growing electricity demand. Despite significant economic, environmental, and resiliency benefits, integrating DER, including power electronic devices, into the existing power networks causes stability and power quality issues. Therefore, to meet stability and power quality standard limits, a sort of compensation using cost-effective and energy-efficient technologies and power electronics-based concepts is needed. This paper presents a novel configuration of compensating type custom power devices (CPDs) and fault current limiters (FCLs) for limiting balanced and unbalanced faults and improving the transient performance of distributed generation (DG) sources in a hybrid power system. Moreover, three power grid operational scenarios are addressed to reflect the impact of the type of fault and variable power generation capacity of DGs on transient stability. Four configurations are implemented using two FCLs (BFCL and SFCL) and two energy compensation devices (DVR and UPQC). The transient performance of involved DGs with and without applying proposed compensation methods is simulated. Simulation experiments were carried out using MATLAB/SIMULINK software. The simulation results indicate that UPQC- BFCL is the best solution in all scenarios that improve the transient stability of the proposed power system under both balanced and unbalanced faults. پرونده مقاله

  With the development of critical loads, power quality problem has become particularly important and poor power quality will be cause many adverse effects and the cost of many deaths will follow. To improve power quality and protection of sensitive loads against grid disturbances have been used new equipment based on power electronics similar FACTs devices, they are Custom Power. One of the most important Custom Power Device is DVR that it is used for compensation Swell and Sag voltage in the distribution network. The DVR injected voltage to compensate for the Swell and Sag voltage in distribution network. Compensation voltage accuracy depends on by its ability to design PWM, the controller and choice of filter parameters. For control of DVR can be used traditional controller, such as PI, PID and intelligent controller, such as fuzzy controller. In This paper, Fuzzy controller is used for controlling DVR in the Distribution Network. پرونده مقاله
