“…On the other hand, compliance of harmonics with standard regulations does not necessarily mean that it is not a source of concern for microgrids. The fact that its value increases along with the penetration of renewable energies and the battery bank, adds to other findings from other studies [17,18].…”

“…2-2008 [20]. In [18], it was found that the third current harmonic is relatively high and, as such, special attention should be paid to it. Additionally, it was found that current harmonics and the TRD index increase with the penetration level of renewable sources, as shown in the first 3 scenarios.…”

This article assesses the impact on the Power Quality produced by the interconnection of a microgrid to a transmission system, real-time simulation have been used to carry out the study, applying national and international power quality standards, IEEE 1547 of 2018, IEEE 519 of 2014 and NTC 5001 of 2008. The phenomena of voltage harmonics, current harmonics, flicker and DC injection were evaluated on a microgrid case study. The results show that the interconnection of the microgrid produces a high impact on the current harmonics and the DC injection of the local transmission system, while the flicker phenomena and voltage harmonics have a smaller impact.

“…The placement and number of EV loads and WGs impact the voltage profile in the distribution network. Similarly, studies have shown that uncoordinated charging of EVs leads increased peak demand, which impacts the overall reliability of the grid [3,4]. Also, the presence of EVs can cause increased power losses and power quality issues including harmonic distortions in the distribution grids.…”

Power-electronic interfacing based devices such as wind generators (WGs) and electrical vehicles (EVs) cause harmonic distortions on the power grid. Higher penetration and uncoordinated operation of WGs and EVs can lead to voltage and current harmonic distortions, which may exceed IEEE limits. It is interesting to note that WGs and EVs have some common harmonic profiles. Therefore, when EVs are connected to the grid, the harmonic pollution EVs impart onto the grid can be reduced to some extent by the amount of wind power injecting into the grid and vice versa. In this context, this work studies the impact of EVs on harmonic distortions and careful utilization of wind power to minimize the distortions in distribution feeders. For this, a harmonic unbalanced distribution feeder model is developed in OpenDSS and interfaced with Genetic Algorithm (GA) based optimization algorithm in MATLAB to solve optimal harmonic power flow (OHPF) problems. The developed OHPF model is first used to study impact of EV penetration on current/voltage total harmonic distortions (THDs) in distribution grids. Next, dispatch of WGs are found at different locations on the distribution grid to demonstrate reduction in the current/voltage THDs when EVs are charging.

<span lang="EN-US">Modern wind farms are considered one of the most important sources of energy today. The biggest cost of the farm is the cost of electrical connection to the farmers (constituting the largest part of the aesthetic cost of the farm) and finding the best method for electrical connection (the optimal method) for wind turbines (WTS), as well as the optimal size and measurement of electrical cables. Here, the (harmonious) search algorithm solves the optimization problem and the method of digging the soil in order to lay the cables in it. Two cases will be discussed in order to calculate the optimal size of the cables, namely partial calculation and optimal calculation for connection schemes in the best method for wind farms (OWFS). Also, the total cost, shipping methods, methods of digging extensions into the soil and the different classifications for turbines (wind turbines) will be addressed in order to obtain the best investment for them, so that we reach the optimal delivery and the lowest possible cost in a coordinated and thoughtful manner.</span>
