Distributed Coordinated Reactive Power Control for Voltage Regulation in Distribution Networks

IEEE Transactions on Smart Grid, 2021
In this article, a novel distributed coordinated control framework is proposed to handle the uncertain voltage violations in active distribution networks. It addresses the problem of coordination of different types of devices in a distributed manner.

Grid-Synchronization Stability Analysis and Loop Shaping for PLL-Based Power Converters With Different Reactive Power Control

IEEE Transactions on Smart Grid, 2020
Power converters may lose synchronization with the remaining network when integrated in a weak power grid. Such an instability phenomenon [known as grid-synchronization instability (GSI)] features the frequency divergence of phase-locked loop (PLL) and ...

Reactive Power Control of Compound Reactive Power Compensation Device

2018 IEEE International Conference on Mechatronics and Automation (ICMA), 2018
A low-cost composite reactive power compensation model is proposed. The model consists of a Thyristor Switched Capacitor (TSC), a Thyristor Controlled Reactor (TCR) and a Static Var Generator (SVG). Firstly the paper completes the preliminary compensation by the large-capacity TSC+TCR module, and then the small-capacity SVG is responsible for ...

Towards reactive power markets. Part 1: reactive power allocation

IEE Proceedings - Generation, Transmission and Distribution, 2006
Although real power is the main traded commodity in electricity markets, reactive power plays a crucial role in power systems reliability and security. In competitive electricity markets, no market participant wants to subsidise others in any way. Market participants utilise the network in different ways to maximise their profits.

ITER Reactive Power Compensation Systems: analysis on reactive power sharing strategies

2019 IEEE International Conference on Environment and Electrical Engineering and 2019 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2019
The goal of nuclear fusion is one of the most important challenges in contemporary research and technological development. Its achievability will completely change the energy scenario and reduce the dependence on fossil fuels in the production of electricity. ITER project is focusing the efforts of many countries and researchers in the demonstration of

Optimal Phase-Shift Control to Minimize Reactive Power for a Dual Active Bridge DC–DC Converter

IEEE transactions on power electronics, 2019
In a dual active bridge (DAB) dc–dc converter, modulating the phase-shift ratios can suppress reactive power and increase the efficiency under non-unity voltage gain conditions. Derivation of the optimal phase-shift ratios to achieve the minimum reactive
