“…The field of power quality includes many different phenomena such as harmonic distortion, which is one of the most important issues studied in the power grid, owing to the rise in non-linear loads (NLLs) [1]. Similarly, harmonic distortion represents a significant power quality challenge within hybrid microgrids, alongside voltage fluctuations, imbalance occurrences, and the critical need for fault ride-through capability on both the DC and AC sides [2,3]. Nowadays, the use of NLL has become very common in industrial sectors.…”

Nowadays, nonlinear loads are widely employed within the industrial applications that cause harmonic distortions in the network. Passive harmonic filters stand out as the preeminent and cost‐efficient remedy for mitigating the impact of harmonic distortions. Any changes in power system conditions such as load variability and photovoltaic resources uncertainty have a significant impact on the harmonic conditions which can affect the quantity and positioning of passive harmonic filters. Hence, in this paper, a method including an innovative optimization problem is proposed for probabilistic planning of passive harmonic filters considering system conditions variability, which is solved by heuristic methods and multi‐criteria decision‐making techniques. By doing this, a solution is obtained where grid losses and the passive harmonic filter costs are minimized and the power factor and frequency response are improved on selected buses. Also, in this paper, the index that gauges the severity of total harmonic distortion is proposed to determine the worst case of the network in terms of harmonic distortions which is so vital for system operators, especially the systematic approach to designing passive harmonic filters. To indicate the efficiency of the proposed approach, the electrical system of an actual Iranian copper mine of significant scale is employed, featuring the integration of non‐linear loads.

This report first analysis quasi static power flow for photovoltaic power plant. Then, fault analysis for different symmetrical and asymmetrical fault is done. The system used is IEEE 39 bus New England system that a Photovoltaic farm with 500 MW power is connected to bus 24. Newton-Raphson Power flow method is used with Gauss-Jordan elimination method for matrix inversion in this power flow analysis. Different operation condition including faults are also considered for fault at bus 16. The results are validated with simulation in MATLAB software.

A new structure of the Marx pulse generator for generating bipolar high-voltage pulses is introduced. This structure is composed of a buck-boost converter and connected to a low DC voltage source and several parallel diode-capacitor units. In the first stage, the inductor energy is supplied through the voltage source and in the next stage, the inductor energy is transferred to capacitors. For generating the pulses, voltage polarities of the capacitors are changed by a small inductor which is in resonant with the capacitors. Then, using a fast switch, the capacitors are connected in series to generate desirable high-level pulses. To have bipolar pulses, polarity of capacitors is inverted, alternatively. Modularity of the proposed structure enables us to increase number of the units for generating higher voltage level, straightforwardly.
