Review on Recent Strategies for Integrating Energy Storage Systems in Microgrids

Abstract

Energy security and the resilience of electricity networks have recently gained critical momentum as subjects of research. The challenges of meeting the increasing electrical energy demands and the decarbonisation efforts necessary to mitigate the effects of climate change have highlighted the importance of microgrids for the effective integration of renewable energy sources. Microgrids have been the focus of research for several years; however, there are still many unresolved challenges that need to be addressed. Energy storage systems are essential elements that provide reliability and stability in microgrids with high penetrations of renewable energy sources. This study provides a systematic review of the recent developments in the control and management of energy storage systems for microgrid applications. In the early sections, a summary of the microgrid topologies and architectures found in the recent literature is given. The main contributions and targeted applications by the energy storage systems in the microgrid applications is defined for each scenario. As various types of energy storage systems are currently being integrated for the reliable operation of the microgrids, the paper analyses the properties and limitations of the solutions proposed in the recent literature. The review that was carried out shows that a hybrid energy storage system performs better in terms of microgrid stability and reliability when compared to applications that use a simple battery energy storage system. Therefore, a case study for a DC microgrid with a hybrid energy storage system was modelled in MATLAB/Simulink. The presented results show the advantages of hybrid energy storage systems in DC microgrids.

Performance Assessment User Interface to Enhance the Utilization of Grid-Connected Residential PV Systems

“…The integration of energy storage systems for DG applications, for backup generation and improved power quality purposes, was discussed by many researchers [44][45][46]. It is concluded from the reviewed studies that integrating bulky ESSs to the PV generation units, for backup power, has undeniable drawbacks.…”

New Horizons for Microgrids: From Rural Electrification to Space Applications

“…Consequently, the integration and management of energy storage systems in microgrids is a heavily researched topic. Various types of ESS technologies have been considered in the literature to date that can be categorized into mechanical, electrical, battery, thermal, electrochemical and chemical [10]. Recently, there has also been a shift towards hybrid energy storage systems that typically consist of battery energy storage systems coupled with another storage element [15].…”

“…In recent dec ades, microgrid technologies, architectures and control strategies have been extensively researched to increase their reliability and scalability. These ongoing research efforts can be grouped into the following categories: hierarchical control loops and architectures [1][2][3][4][5][6], microgrid clusters and multi-microgrids [7][8][9], integration and management of energy storage systems [10][11][12][13][14][15] and peer-to-peer energy trading and new roles for prosumers [16,17].…”

Wind–PV–Battery Hybrid Off-Grid System: Control Design and Real-Time Testing

“…To balance and compensate for fluctuations in power using a hybrid AC/DC configuration for an off-grid system, an energy storage element is suggested [12]. Connecting this element to the system often requires power converters to step up or down the voltage, such as Cuk, SEPIC, etc., [13,14].…”
