“…Although some of these works do not explicitly specify the requirements of the measurement system [58], [157], [179], [184], the proposed controllers rely on fast-response measurements and hence we include them within the group of PMU-based systems. Nevertheless, several publications do not specify the measurement system, nor the requirements for such measurement system, thus remaining unclear upon which platform the controls where designed (WAMS, SCADA, and/or another monitoring system) [120], [149], [159], [201], [203], [212], [213], [215], [216], [219], [222], [229], [243], [244], [254].…”

“…In most cases, Static VAR compensator (SVC)-based approaches have been proposed, using the capability of SVCs of providing fast-acting reactive power [104], [118], [119], [124], [134], [135], VOLUME 11, 2023 [140], [174], [176], [181], [236], [250]. Furthermore, other FACTS-based approaches use thyristor controlled series capacitor (TCSC) [136], [144], [163]; static synchronous series compensator (SSSC) [173]; unified power flow control (UPFC) [179]; and static synchronous compensators (STAT-COM) [120], [189]. Some approaches have also considered more than one type of FACTS device simultaneously, such as in [122] and [248], where both SVC and TCSC are considered within the control strategy.…”

“…Several works modify traditional control strategies of common system elements by including an additional loop to their control system using wide-area signals to enhance the control performance of power systems. Among these works are [55], [108], [110], [111], [112], [115], [119], [120], [121], [228], [230], [241], [245], [250], and [255]. Traditional PI and PID controllers have also been studied, as presented in [56], [106], [107], and [118].…”

Countries around the world are transitioning from conventional power systems dominated by synchronous generators towards low-carbon resources, characterized by high levels of converter-interfaced generators (CIGs). With this transformation, hundreds or even thousands of fast power electronic devices will be added to the grid as CIG penetration increases, thus making the system dynamic response progressively faster and more complex. This future scenario poses significant challenges in power system stability and control. To sustain power system stability in future power systems and achieve a seamless transition, we need to depart from current control practices based on decentralized and stand-alone local control actions and begin to explore new methods. A promising technology to overcome control complexities and underlying stability issues in future low-inertia power systems are wide area control (WAC). Within this technology, the control is no longer based on a purely localized tasks but rather a set of coordinated actions across wide areas in which interplant communication plays a key role. This paper presents the state of the art of existing research efforts in the field of WAC strategies for maintaining stability in large-scale low-inertia power systems of the future. We present different WAC solutions that have been put forward hitherto, we put these control strategies into context, classify them, and finally relate them to each other. We also raise open questions and challenges that need to be addressed in order to ensure a secure transition towards power systems dominated by CIGs.

“…In 2016, the National Energy Administration promulgated the "Thirteenth Five-Year Plan for Energy Development", which pointed out that my country's clean energy replacement task is arduous, and the environmental carrying capacity of energy production and consumption in some areas is close to the upper limit. In order to cope with climate change and promote low-carbon, green and sustainable development, renewable energy (Renewable Energy, RE) is listed as the main energy source in the "13th Five-Year Plan" [1][2], and it is proposed that by the end of 2030, renewable energy will be The proportion of renewable energy consumption has increased to more than 20%. However, it is found in actual projects that the initial construction cost of renewable energy is too high, and the operation control is difficult [3], and its output power is subject to natural climate, which has certain volatility and uncontrollability [4].…”

As the core equipment of hybrid microgrid, power electronic transformer is a new type of multifunctional transformer which integrates power electronic technology, information communication technology and control protection technology. On the background of the Beijing Low-Carbon Winter Olympics Smart Grid Demonstration Project, this paper proposed an AC/DC hybrid microgrid topology with dual-end power supply based on power electronic transformer. Moreover, a coordinated optimization control for AC/DC hybrid microgrid based on power electronic transformer is studied. The content of the paper mainly includes: The common topology of power electronic transformer is studied, and a three stage four-port power electronic transformer is proposed according to the demand of demonstration project. The interface converter topology structure and control method of distributed generation and energy storage in hybrid microgrid are analyzed, and the system model of hybrid microgrid is established. Simulation results show that MPPT control can maximize the power output of distributed generation, and piecewise droop control can realize seamless switching between power control and voltage control in the grid-tied or autonomous mode.
