“…On the transmission line, the EMTR-based fault location relies solely on the time-reversal invariance of the telegraph equations [36]. The Fourier transform of a function f(t) that integrates a real and symmetric window at frequency w is the short time-frequency transforms (STFT) (t) [37]. Time is used to translate it, and frequency is used to modulate it.…”

The world's energy consumption and power generation demand will continue to rise. Furthermore, the bulk of the energy resources needed to satisfy the rising demand is far from the load centers. The aforementioned requires long-distance transmission systems and one way to accomplish this is to use high voltage direct current (HVDC) transmission systems. The main technical issues for HVDC transmission systems are loss of synchronism, variation of quadrature currents, amplitude, the inability of station 1 (rectifier), and station 2 (inverter) to either inject, or absorb active, or reactive power in the network in any circumstances (before a fault occurs, during having a fault in network and after a fault cleared), and the variations of power transfer capabilities. Additionally, faults impact power quality such as voltage dips and power line outage time. This paper presents a method of overcoming the aforementioned technical issues using voltage-source converter (VSC) based HVDC transmission systems with SCADA VIEWER software and dynamic grid simulator. The benefits include having a higher capacity transmission system and proposed best method for control of active and reactive power transfer capabilities. Simulation results obtained using MATLAB validated the experimental results from SCADA Viewer software. The results indicate that the station's rectifier or inverter can either inject or absorb either active power or reactive power in any circumstance. Also, the reverse power flow under different modes of operation can ride through faults. At a 100.0% power transfer rate, the rectifier injected 775.0 W into the network. At a 0.0% power transfer rate, the rectifier injected 164.0 W into the network. At a −100.0% rated power, the rectifier injected 1264.0 W into the network and direction was also changed.

“…Photovoltaic is one of the most widespread renewable sources because it is clean, inexhaustible, low maintenance and distributed all over the world. Normally, DGs are small 1 KW to 100 MW active power generators which are connected at the distribution level [1] [2]. Active government measures have been taken to encourage the need to use solar energy, which is abundant in nature, and to install autonomous photovoltaic technology (photovoltaic roof) to meet increasing load demands and reduce electricity bills.…”

Distributed generators using environmentally friendly energy sources such as wind, small water and solar energy have become an important part of the future smart grid/micro grid concept. Design of an autonomous photovoltaic system to study the reaction of solar modules to variable irradiation conditions and their effect on loads. The autonomous system must include a battery storage system to handle non-linear load responses on the AC side. And improve the output power of the photovoltaic system using the MPPT algorithm specially designed to drive linear and non-linear loads on stand-alone systems. And causing the system to respond to varying levels of radiation in the environment and achieve an uninterrupted regulated output of the system. The system examined the behavior of linear and non-linear loads with constant irradiation of 1000 wb / m2 and then modified it to a value between 1000 wb / m2 and 200 wb/m2. The harmonic content in the line voltage increased to 3.34% with a non-linear load by 0.54% with a linear load.
