“…The electrical energy production from RES and its integration in distribution systems has been growing at a dizzying pace in the last several years. In [107], a flywheel ESS was interfaced with distribution systems by an SST, with the excess wind energy stored in the flywheel and then restored during the energy-shortage periods. This combination of the flywheel ESS and SST allows for improving transient stability, increasing the bidirectional power transfer capability and provides a better response with the random variation of wind power and with power grid demand change.…”

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.

Grid operators and wind farm vendors often employs multiple circuitries including but not limited to line frequency transformer (LFT), static synchronous compensator (STATCOM) and power factor correction (PFC) devices for grid integration of wind farms. Such components are usually heavy, noisy and causes greenhouse effect. The bulky power transformers for both STATCOM and the wind farm generator hinders this configuration from applications where volume and weight are issues. As such, STATCOM-interfaced wind farm cannot be sited where size, weight, compactness, cable solution, multiport capability and environmental friendliness are critical. This paper demonstrate how solid state transformer (SST) replaces the STATCOM, the bulky transformers, and the additional reactive power compensation devices in grid integration of wind farms thereby providing smaller footprint, compactness and high performance. It is concluded that, SSTinterfaced wind farms can be sited anywhere because of the reduced size, weight, compactness, cable solution, multiport capability and environmental friendliness.

“…A flywheel energy storage device can rapidly change ample power that can be utilized to control additional energy during a low-voltage disturbance. In a flywheel ESS-based FRT support, excess energy is collected as kinetic energy depending on the rotating speed and mass [38][39][40][41][42][43][44][45][46]. Flywheel energy storage is connected with an HVDC-link through a separate MMC to mitigate wind energy fluctuation [41].…”

Battery Power Control Strategy for Intermittent Renewable Energy Integrated Modular Multilevel Converter-Based High-Voltage Direct Current Network

Modular multilevel converters (MMC) play a dominant role in integrating remotely located renewable energy resources (RER) over the high-voltage direct current (HVDC) transmission network. The fault ride-through capabilities of the MMC-HVDC network during low-voltage faults and the power fluctuation due to RER intermittency are the major obstacles to the effective integration of renewable energy. In response, this article proposes a local voltage-based combined battery energy control scheme for a PV-wind-battery connected MMC-HVDC system to regulate the HVDC-link voltage during low-voltage faults at the point of common coupling of alternating current grids and to reduce the intermittent RER power fluctuation. The proposed technique removes the dynamic braking resistor from the HVDC-link and smoothly integrates the RER without active power reduction of renewable energy under low-voltage faults. Symmetrical and unsymmetrical low-voltage faults have been conducted to validate the effectiveness of the proposed control scheme for the battery in mitigating surplus energy in the HVDC-link. Additionally, wind speed, solar radiation, and temperature have been changed to confirm the improved performance of the battery energy management system. The complete systems have been simulated and tested in a real-time digital simulator (RTDS) and using dSPACE-based controller hardware in a loop setup.
