Recently, as wind energy has increased considerably in the electric power generation system, the wind turbines must maintain connected to the grid and improve the system stability during and after the grid faults. The enhancement of fault-ride through (FRT) capability of permanent magnet synchronous generator (PMSG) based on wind energy conversion system (WECS) is a vital issue. An active crowbar protection system in this paper is proposed to the improvement of FRT capability and the enhancement of the power quality of PMSG based on WECS system during and after the grid faults. The active crowbar in this paper is designed from a series resistor with an insulated gate bipolar transistor (IGBT) switch, unlike the passive crowbar, which has only one resistor. The active crowbar protects the power converters from the damaging effects of overcurrent during grid fault. The main aims of the active crowbar system are reduction of the amplitude of stator fault voltages, remains constant DC link voltage, general enhancement in all response of the PMSG, minimizing in the trigger time of the active crowbar. These aims are achieved with the introduction of the active crowbar between the machine side converter (MSC) and PMSG. The proposed protection system implemented a 1.5MVA PMSG based on WECS during different grid faults conditions using MATLAB/Simulation. The proposed protection system is compared with without protection system during different faults conditions and the validity of the proposed protection system is verified by simulation results.

Recently, the permanent magnet synchronous generator (PMSG) has been gained attention by wind turbine (WT) manufactures due to advance of control system and power electronics. The permanent magnet synchronous generator based on three level neutral point control (NPC) system using fuzzy logic control proportional integral (FLC PI) is proposed in this study. The NPC systems of DC link are implemented more easily t h a n t w o l e v e l s y s t e m s. T h e N P C s y s t e m s p r o v i d e b e t t e r harmonic reduction than conventional two level voltage source converters. The control strategies of the NPC systems reduce semiconductor losses. The proposed system can be implemented to the multi-level converters above three-level. The proposed system is developed using the steady state technique. The performance of the PMSG system under variation operation condition is investigated in this study and the performances of the PMSG based on three level NPC using FLC PI are analyzed. The validity of the proposed system is implemented and verified in the MATLAB/Simulink using three-level insulated gate bipolar transistor (IGBT) converter.

“…The permanent magnet synchronous generator (PMSG) is commonly utilized in the WECS. However, the PMSG is robust and does not need separate field control (Gencer, 2016). The SPVS and WECS are coupled to the point of common coupling (PCC) by power inverters.…”

Interconnecting two or more microgrids can help improve power system performance under changing operational circumstances by providing mutual and bidirectional power assistance. This study proposes two interconnected AC microgrids based on three renewable energy sources (wind, solar, and biogas). The wind turbine powers a permanent magnet synchronous generator. A solar photovoltaic system with an appropriate inverter has been installed. In the biogas generator, a biogas engine is connected to a synchronous generator. M1 and M2, two interconnected AC microgrids, are investigated in this study. M2 is connected to a hydro turbine, which provides constant power. The distribution power loss, frequency, and voltage of interconnected AC microgrids are modeled as a multi-objective function (OF). Minimizing this OF will result in optimal power flow and frequency enhancement in interconnected AC microgrids. This research is different from the rest of the research works that talk about the virtual inertia control (VIC) method, as it not only improves frequency using an optimal controller but also achieves optimal power flow in microgrids. In this paper, the following five controllers have been studied: proportional integral controller (PI), fractional-order PI controller (FOPI), fuzzy PI controller (FPI), fuzzy fractional-order PI controller (FFOPI), and VIC based on FFOPI controller. The five controllers are tuned using particle swarm optimization (PSO) to minimize the (OF). The main contribution of this paper is the comprehensive study of the performance of interconnected AC microgrids under step load disturbances, the eventual grid following/forming contingencies, and the virtual inertia control of renewable energy resources used in the structure of the microgrids, and simulation results are recorded using the MATLAB™ platform. The voltages and frequencies of both microgrids settle with zero steady-state error following a disturbance within 0.5 s with less overshoots/undershoots (3.7e-5/-0.12e-3) using VIC. Moreover, the total power losses of two interconnected microgrids must be considered for the different controllers to identify which one provides the best optimal power flow.
