“…As such, the types of services that may be provided are only the ones that fit with the TES characteristics. In particular, with respect to electrical energy storage, which can provide relatively fast services at sub-second time scale, e.g., for power quality improvement, grid stability enhancement, and short-time backup power [22,23], a TES system has slower response due to its intrinsic thermal capacity that affects the thermal transients [24]. At the same time, heat (or cooling) cannot be stored for a long time, because of the thermal losses due to the difficulty in insulating the storage devices.…”

Thermal energy systems (TES) contribute to the on-going process that leads to higher integration among different energy systems, with the aim of reaching a cleaner, more flexible and sustainable use of the energy resources. This paper reviews the current literature that refers to the development and exploitation of TES-based solutions in systems connected to the electrical grid. These solutions facilitate the energy system integration to get additional flexibility for energy management, enable better use of variable renewable energy sources (RES), and contribute to the modernisation of the energy system infrastructures, the enhancement of the grid operation practices that include energy shifting, and the provision of cost-effective grid services. This paper offers a complementary view with respect to other reviews that deal with energy storage technologies, materials for TES applications, TES for buildings, and contributions of electrical energy storage for grid applications. The main aspects addressed are the characteristics, parameters and models of the TES systems, the deployment of TES in systems with variable RES, microgrids, and multi-energy networks, and the emerging trends for TES applications.

“…More recently, the integration of hybrid ESSs into DERs has been proposed to facilitate the implementation of ancillary services such as inertia emulation, black start, or power oscillation damping [114,115]. The authors of [115] propose a device that combines the large storage capacity of electrochemical batteries and the high dynamic performance of the supercapacitors. The system is controlled to provide frequency support, and a power sharing control strategy is implemented such that the supercapacitor bank delivers the high-frequency component of the demanded active power, while the battery injects the average power.…”

The number of battery energy storage systems (BESSs) installed in the United Kingdom and worldwide is growing rapidly due to a variety of factors, including technological improvements, reduced costs and the ability to provide various ancillary services. The aim of this paper is to carry out a comprehensive literature review on this technology, its applications in power systems and to identify potential future developments. At first, the main BESSs projects in the UK are presented and classified. The parameters provided for each project include rated power, battery technology and ancillary services provided, if any. In the next section, the most commonly deployed ancillary services are classified and described. At the same time, the nomenclature found in the literature is explained and harmonised. The second part of the paper focuses on future developments and research gaps: ancillary services that currently are not common but that are likely to be deployed more widely in the future will be described, and more general research topics related to the development of BESSs for power system applications will be outlined.

“…Recently, renewable energies have been increasingly used to meet growing energy demands and mitigate climate change caused by the greenhouse effect due to the burning of large amounts of fossil fuels. Batteries are often used in energy storage systems to compensate the power fluctuation between renewable power generation systems and consumption [1][2][3]. Since battery voltage is usually small and has a wide range of variation, a high step-up dc/dc converter is indispensable on application where high dc voltage is required [4][5][6].…”

An Interleaved DC/DC Converter with Soft-switching Characteristic and high Step-up Ratio

et al. 2020

This study presents a dc/dc converter featuring soft-switching characteristic, high conversion efficiency, and high step-up ratio. The proposed circuit is composed of two parallel-connected boost converters. Only one coupled inductor is used to replace inductors of the boost converters which are interleaved operated at discontinuous-conduction mode (DCM). The current ripples at the input and the output terminals are reduced due to the interleaved operation. By freewheeling the current of the coupled inductor to discharge the stored electric charges in the parasitic capacitors of the active switches, both active switches can fulfill zero-voltage switching on (ZVS). Owing to DCM operation, the freewheeling diodes can fulfill zero-current switching off (ZCS). Therefore, the power conversion efficiency is improved. The operation principle for each operation mode is analyzed in detail and design equations for the component parameters are provided in this report. Finally, a prototype 200 W 48–400 V converter was implemented and measured to demonstrate the effectiveness of the proposed circuit.
