Summary The distributed generation (DG) is getting extensively integrated in existing power distribution system because of the massive development in green energy technologies and their economical, technical, and environment benefits. However, apart from beneficial aspects, DGs also have various and complex technical limitations, major of which are loss of protection coordination among protection devices which can lead to malfunctioning of protection devices, blind protection, fuse blowing, and permanent outage of power supply due to temporary faults. In this paper, a novel curve fitting technique is designed to restore much influenced recloser‐fuse coordination using the directional properties of midline recloser for upstream and downstream protection devices coordination. It also works on fuse‐saving scheme. Using Electrical Transient Analysis Program (ETAP) Software, the proposed methodology is implemented on a real 11 kV Rajewala radial distribution feeder starting from 132 kV Eimnabad grid station, district Gujranwala, Pakistan. Present here are some key results. Different case studies are carried out and results validate the effectiveness of the proposed methodology, and the coordination among protection devices is sustained even after DGs integration in the system.

“…As DBR has only the active power control ability, it is good idea to incorporate reactive power compensating device along with DBR. For stability augmentation of fixed speed WTGS, series dynamic braking resistor (SDBR) [29][30][31] is more effective than DBR with shunt-connected topology [26][27][28]. In [29][30], a simulation analysis is performed using only one fixed speed WTGS that connects the grid.…”

“…That study is symmetrical to distributed topology where each SDBR is connected close to the individual wind generators and differs significantly from the centralized topology using only one SDBR installed at the wind farm terminal. Incorporation of SDBR with dynamic voltage restorer (DVR) increases the system cost due to the presence of transformer and LC filter [31]. In the earlier works with SDBR [29][30][31], the effect of other synchronous generators that exist in a realistic power system is not evident.…”

This paper presents a method to enhance the stability of grid connected wind farm composed of fixed speed wind turbine generator system (WTGS) using a combination of small size series dynamic breaking resistor (SDBR) and static synchronous compensator (STATCOM). SDBR and STATCOM have the active and reactive power control abilities, respectively, and a combination of these units pave the way to stabilize well the fixed speed wind farm. In this study, centralized control scheme of using SDBR and STATCOM in together is focused, which can be easily integrated with wind farm. Different types of symmetrical and unsymmetrical faults are considered to evaluate the transient performance of the proposed control scheme, applicable to grid connected wind farm. The effect of multi-mass drive train of fixed speed WTGS in fault analysis along with its importance in determining the size of SDBR to augment the transient stability of wind farm is investigated. Extensive simulation analyses are performed to determine the approximate sizes of both SDBR and STATCOM units. Dynamic analysis is performed using real wind speed data. A salient feature of this work is that the effectiveness of the proposed system to minimize the blade-shaft torsional oscillation of fixed speed WTGS is also analyzed. Simulation results show that a combination of small size SDBR and STATCOM is an effective means to stabilize the wind farm composed of fixed speed WTGS.

“…Many devices, such as static var compensator (SVC), dynamic voltage restorers (DVR), Static Synchronous Compensators (STATCOM) etc have been shown to improve FRT of WECS, but they will also increase the overall cost of the system [8][9]. In [10], a non linear controller design for power converter based WT system is presented which ensures that current levels remain within design limits, even at greatly reduced voltage levels.…”

Permanent magnet Synchronous Generators (PMSG) are becoming popular for wind energy conversion systems (WECS) nowadays due to the possibility of gearless operation even in grid connected mode. However, these systems have serious problems during fault conditions such as over speeding of the generator speed and undue increase in the DC link capacitor voltage. This paper proposes a complete coordinated control of the generator and the power electronic converters to achieve fault-ride-through (FRT) capability. The analysis and simulation of a PMSG based WECS is presented here for normal working conditions as well as for fault conditions. The uniqueness of the model includes de-loading of the generator via machine side converter, active and reactive power control through grid side converter to support voltage control during fault. The simulation results prove the capability of the system to harness maximum power during normal conditions and to achieve FRT during a severe three-phase fault.
