Aiming at the grid security problem such as grid frequency, voltage, and power quality fluctuation caused by the large‐scale grid‐connected intermittent new energy, this article investigates the life cycle assessment of energy storage technologies based on the technical characteristics and performance indicators. First, the new power system under dual‐carbon target is reviewed, which is compared with the traditional power system from the generation side, grid side, and user side. Based on the power characteristics of the new power system, the energy storage mechanism and energy storage characteristics of mechanical energy storage, electrochemical energy storage, chemical energy storage, electromagnetic energy storage, and thermal energy storage are described. Then, compared with the existing research strategies, a comprehensive life cycle assessment of energy storage technologies is carried out from four dimensions: technical performance, economic cost, safety assessment, and environmental impact. Moreover, the suitable scenarios and application functions of various energy storage technologies on the power generation side, grid side, and user side are compared and analyzed from the working principle, key technologies, advantages and disadvantages, and technical difficulties of energy storage technologies. Finally, combined with the energy storage technologies in the electricity market, four profit models are analyzed.

“…To address these issues, power quality regulation devices, such as static var compensator (SVC) (Tang et al, 2024), dynamic voltage restorer (DVR) (Gao et al, 2023), and active power filter (APF) (Zhang et al, 2017), have emerged, which can only solve a single power quality problem. Based on the APF, Japanese scholars proposed the concept of a unified power quality conditioner (UPQC) (Fujita and Akagi, 1996), which combines the functions of DVR and APF and can compensate for multiple power quality problems simultaneously (Wei et al, 2019;Han et al, 2022;Elik and Ahmed, 2023;Lakhdar et al, 2023). How to control the UPQC to better compensate for power quality is currently a significant area of research among scholars.…”

To solve the delay problem of a unified power quality conditioner (UPQC) system during the separation of the fundamental positive-order components and to better filter out the DC and harmonic components to realize accurate phase locking, a mixed second- and third-order generalized integrator phase-locked loop (MSTOGI-PLL) has been designed to replace the traditional synchronous reference frame phase-locked loop (SRF-PLL). Under the premise of adopting the new phase-locking device of MSTOGI-PLL, the active disturbance rejection control (ADRC) controller or the super-twisting algorithm (STA) sliding mode controller is used in the DC voltage control module instead of the traditional PI controller, and the suitability of the two nonlinear controllers with the MSTOGI-PLL device is investigated. First, the new MSTOGI-PLL device is designed, and the new phase-locking method is applied to make the UPQC realize accurate phase locking under the non-ideal situation of the grid voltage containing unbalance, DC component, harmonics, and so on. Based on the above foundation, the ADRC or STA controller is independently adopted to replace the PI controller to construct the UPQC system with the ADRC + MSTOGI phase-locking device and the second-order STA + MSTOGI phase-locking device. Finally, a simulation comparison is carried out in a Simulink simulation platform regarding the UPQC system under different phase-locking devices, and the simulation results demonstrate that MSTOGI-PLL can successfully filter out the DC component and resolve the phase-locking process delay issue. Additionally, the UPQC system with ADRC + MSTOGI-PLL exhibits superior immunity and response speed to the PI controller and the second-order STA controller.

The integration of Photovoltaic (PV) systems with a Unified Power Quality Conditioner (UPQC) is examined in this presentation. Shunt and series voltage compensators linked back-to-back with a common dc-link compose the PV-UPQC. The series active power filter ensures the maintenance of the desired magnitude without distortion. Meanwhile, the shunt active power filter injects harmonic currents into the grid with equal amplitude and opposite phase, obtained by utilizing the PQ theory technique for shunt APF control and the Unit Vector Template Generation (UVTG) approach for series APF control. The study reveals promising results in terms of improved power quality, harmonics reduction, and effective voltage stabilization.
