In recent years, the domination of power electronics-interfaced renewable energy source (RES) such as solar photovoltaic (PV) system causes grid frequency instability issue. This paper proposes a new machine learning (ML)-based virtual inertia (VI) synthetization in synchronverter topology to integrate PV and with high-frequency stability. The proposed ML-based VI is synthetized by amalgamating action critic network decouple active reactive control. Therefore, exhibits decoupled control...

In recent years, renewable energy sources, specifically solar power systems, have developed rapidly owing to their technological maturity and cost effectiveness. However, its grid integration deteriorates frequency stability because of insufficient rotating masses inertial response. Hence, a synchronverter, which is an inverter that mimics the operation synchronous generator, crucial interface in grid. It stabilizes by emulating virtual inertia. conventional proportional-integral (PI)-based...

The use of distributed generation (DG) within distribution systems has increased for the last two decades due to worldwide increase in demand electricity and governmental policy change from “conventional” energy “green” energy. High levels penetration DG have many significant benefits but also come with drawbacks such as voltage drop power losses. This study presents impact at different locations a feeder terms profile. A radial system is simulated using PSCAD/EMTDC simulation software while...

<p>Voltage control is considered one of the basic operational requirements electrical power systems. The most popular voltage equipment includes On-Load Tap Changer (OLTC) transformer controlled by Automatic Voltage Control (AVC) relay. Recent studies have shown that fuzzy inference systems (FIS) are applicable for tap changing system. In this paper, FIS developed system using Mamdani-type and Sugeno-type models. results two compared. difference between included in paper. It also shows...

Abstract As global population has grown exponentially since the past decade, demand for a sustainable framework cleaner, greener and stable energy production is becoming more important holistic society. Among multiple renewable sources, solar power highly favoured to dominate market due improvements in conversion efficiency reduction cost. Thus, many transmission grids will observe high penetration of inverters as an interface between panels AC grid. Consequently, inverter-dominated grid...

Abstract In recent years, the grid-connected solar power system has grown tremendously because of its cost-effectiveness and environmental friendliness. However, interface to existing grid introduces frequency voltage instability due lack rotating mass inertia response, unlike a conventional synchronous machine. To alleviate limitations, novel adaptive synchronverter is proposed equip with fault ride through in system. It enables continuous electricity generation even under overloading, sag...

Abstract One of the important requirements in electrical power system is to control voltage levels at both distribution and transmission avoid overvoltage or undervoltage conditions. Transformers with mechanical on-load tap changer (OLTC) switches have been considered conventional voltage-control method systems for decades. Due design OLTC, it has several disadvantages, such as poor response time, high loss rates, maintenance cost, demand frequent repair parts. Controlling changes position...
