“…The voltage-controlled methods, such as the voltage-controlled inverter, limit the fault current by forcing the neutral-to-ground voltage to be the opposite of the faulty phase supply voltage without the measurement of the distributed parameters [13]- [15]. However, the inverter-based active arc suppression device (ASD) faces overload capability, high cost, and reliability problems [16]- [20].…”

“…The distribution system plays a vital role in delivering electrical energy to power consumers. Therefore, research in this area has been considered as important, see, for example, Nouri et al 1,2 In recent years, wind generation investment in distribution systems has been increased in many parts of the world. 3,4 Due to the integration of this popular renewable generation in power distribution systems, attention to some technical issues, such as power quality, voltage stability, and protection has been considerably affected.…”

In this paper, a detailed mathematical optimization model of electrolyzer/fuel cell technology connected to the grid through limited rating converters is developed. The model is so defined that it can tackle voltage fluctuation and meet the power ramp rate limitations inflicted by integration of constant-speed wind turbines at the Point of Common Coupling. The flicker mitigation and power ramp rate control problem in the presence of wind generation and variable electrical loads is defined as a nonlinear constrained optimization problem, in which voltage fluctuation is minimized as the objective function and the power ramp rate limitations are respected by the defined real-time ramp rate constraint. The problem is solved using the sequential quadratic programming method, which is a fast solver, by adjusting suitable initial points to be appropriate for real-time applications. The simulation results validate the efficiency of the proposed method and show dramatic improvement in flicker mitigation, power ramp rate control, and system rating reduction in comparison with the proportional–integral control method that was developed in previous studies.

“…The single-ended technique which uses the pre-fault and post fault information was introduced by Takagi firstly [4] [5]. This technique was then modified and extended [6][7][8][9][10][11][12][13][14][15][16] to deal with unknown variables such as the fault distances, the remote-end infeed currents and the fault resistances. Using both the real and imaginary part of the system impedance equations the influences of the fault resistance can be reduced [6][7] [15].…”

“…However, this error increases with the fault resistance and might lead to un-converged iterations. The load impedances are assumed to be not changed and can be derived from pre-fault load flow calculations [9][10], [15][16] but in the distribution level the loading situation can very significantly and this might lead to enlarged fault location errors. When DGs are considered during fault locations [17][18], synchronization is required from all the available measurement nodes and the load impedances have to be a known value.…”

During fault, it is challenging to provide a constant impedance model for DGs in the system frequency due to the variable converter control strategies. System frequency impedance measurement based fault locations can be influenced by the converters' fault behavior. This paper addresses this problem by proposing a wide-area high frequency impedance comparison based fault location technique. The high frequency impedance model of DG is provided. Based on the constant DG impedance model in high frequency range, the faulted line sections can be distinguished by comparing the measured impedance differences without requiring the exact distribution system parameters. Simulation results show that the proposed wide-area transient measurements based fault location method can provide accurate faulted sections in the distribution systems with DGs regardless of the load and DG output variations, measurement noise, unbalanced loads and islanding operations.
