“…The second most popular application consists in using BESSs for deferring investments for the upgrade of the transmission system (TS) and distribution system (DS). Additionally, BESSs have been utilised for the provision of ancillary services such as voltage support, which is gaining increasing importance due to the growing penetration of variable generation and load patterns into the grid, as highlighted in [4], where a detailed investigation and classification of the solutions that mitigate voltage variation is provided. It is expected that the number of installed BESS units will increase simultaneously to the reduction of costs.…”

“…With the increase of BESS installations, coordination between units, with other devices, and with a central controller will gain importance. In the context of the smart grid concept, coordination can be realised with the utilisation of advanced metering infrastructure provided by smart sensors and metres [4]. As a result, increased power quality, grid efficiency and stability will be ensured through the coordinated control of DGs, BESSs and end-user loads, that can respond rapidly to voltage deviations.…”

“…Another difficulty is related to voltage regulation. For example, during periods of high photovoltaic (PV) generation and low demand, the reverse power flow occurring upstream of the PV units results in overvoltages at different nodes, thus increasing the number of operations of switched shunt capacitor banks, load tap changers and line voltage regulators, and consequently reducing their life expectancy [3,4].…”

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.

“…For example, inverters can be programmed to provide ancillary services for power grids under abnormal conditions to improve power quality. This mode of operation for inverters is referred to as grid-supporting mode [1], [2]. Inverters can also operate in grid-forming mode to form an islanded microgrid following a blackout caused by natural disasters, etc.…”

On Grid-Interactive Smart Inverters: Features and Advancements

Traditionally, a grid-interactive inverter providing ancillary services is called a smart inverter. However, broader features will be required for the next generation of inverters that can be categorized as self-governing, selfadapting, self-security, and self-healing. For grid-interactive inverters, the self-governing feature can be identified as the capability of inverters to operate in grid-following and grid-forming control modes, where the self-adapting is referred to as more flexibility realized by adaptive controllers for stable dynamics of inverters under various grid conditions. Moreover, for supervisory control and economic dispatch in a grid with high-penetration of inverter-based power generators, a minimum communication might be necessary, but it can place grid-interactive inverters in danger of being hacked when self-security becomes essential to identify malicious setpoints. Furthermore, the self-healing is defined as fault-tolerance and stress reduction under abnormal conditions. It suggests that after realizing these features, an inverter is called a smart inverter. In this paper, the advancements toward achieving these features for grid-interactive inverters are reviewed. INDEX TERMS Smart inverters, self-security, self-adapting, self-governing, self-healing, cyberattacks.

Demand-Side Power Paradigm-Oriented Analysis of Reactive Electric Spring Stabilization Capabilities

et al. 2020

Electric Spring (ES) technique is a user-level solution developed to stabilize the supply voltage of a user under variations of the grid voltage. This paper analyzes the stabilization capabilities of a reactive ES that operates according to the demand-side power paradigm. By help of a convenient ES modeling, the extreme values of the active power that a user can draw under the ES action are first determined. Then, it is demonstrated that the demand-side power paradigm is fulfilled only if the distribution line impedance has a resistive component while its reactive component weakens such fulfillment. Lastly, the variations of the grid voltage that ES is able to cope with are worked out. All findings are formulated in terms of normalized quantities and consequently are of general validity. Computer-aided simulation of a case study exemplifies the theoretical findings.
