A review ofSTATCOMcontrol for stability enhancement of power systems with wind/PVpenetration: Existing research and future scope

Abstract

In recent years, the development of renewable energy sources (RESs) and their integration with the conventional power network have increased significantly. Due to the power grid transformation brought about by the large penetration of power electronics converter‐based RESs such as wind and solar photovoltaic (PV), the operation and control of the interconnected power system has become a challenging task with respect to sustaining its stability and reliability. Power systems are confronted by several new stability issues because the dynamic behavior of converter‐interfaced renewable sources differs from conventional generation. In this respect, static synchronous compensator (STATCOM), a shunt connected flexible AC transmission system (FACTS), is recognized as a fundamental solution for maintaining power system stability. This paper presents a thorough and state‐of‐the‐art review of STATCOM control in wind‐ and/or PV‐interfaced power systems for enhancing system performance by addressing key stability issues related to rotor angle stability, voltage stability, and resonance stability. A comprehensive analysis of various control techniques of STATCOM based on conventional, adaptive, nonlinear, predictive, robust, and coordinated control and soft computing techniques is provided. Furthermore, the function of the grid‐side converter of the wind/PV plant as a STATCOM is also evaluated. Finally, the shortcomings of existing research are highlighted, current control challenges are presented, and several topics for future research are suggested. This paper provides researchers the opportunity to consider the current state of research and develop new control schemes for STATCOM to further improve the stability of modern power grids.

Performance Analysis of Various FACTS Controllers Used for Voltage Stability Improvement in Power System

“…By placing the FACTS controller in strategic areas, the system will be more protected. The need level of regulation will be achieved for the short circuit current, power flow, and bus voltage (11) . The load side is linked to the FACTS controller (STATCOM) in this article.…”

“…The transient response and overload capacity of STATCOM are better. It has been demonstrated that the STATCOM's position and capacity have a significant influence on enhancing voltage stability (9)(10)(11) .…”

Optimal Placement of Superconducting Magnetic Energy Storages in a Distribution Network with Embedded Wind Power Generation

“…Distribution networks are rapidly integrating Energy Storage Systems (ESS) to address the aforementioned issues and offer other advantages. The former consists of flywheel storage [3], fuel cell storage [4], Compressed Air Energy Storage (CAES) [5], Compressed Carbon Dioxide Energy Storage (CCES) [6], Battery Energy Storage System (BESS) [7], and SMES [8]. Despite being the industry standard, BESSs have serious drawbacks, including a very short lifespan, voltage and current restrictions, potential environmental problems, and a slow response time.…”

Intelligent Integrated Approach for Voltage Balancing Using Particle Swarm Optimization and Predictive Models

“…Diferent voltage balancing techniques have been proposed to ensure that the voltages in the three phases of the system are equal, leading to better performance, improved energy efciency, and reduced equipment damage [8]. Te use of compensators such as static synchronous compensators (STAT-COMs) has shown promising results in voltage balancing in three-phase power systems [9][10][11]. In the next section, an overview of recent developments and state-of-the-art techniques for voltage balancing in three-phase power systems will be presented.…”
