Abstract
Research has found an extensive potential for utilizing energy storage within the power system sector to improve reliability. This study aims to provide a critical and systematic review of the reliability impacts of energy storage systems in this sector. The systematic literature review (SLR) is based on peer-reviewed papers published between 1996 and early 2018. Firstly, findings reveal that energy storage utilization in power systems is significant in improving system reliability and minimizing costs of transmission upgrades. Secondly, introduction of policies to shift from the use of fossil fuels to that of renewable energy positively affects energy storage system development. Thirdly, North America is an early pioneer of power system reliability and energy storage system studies. However, Asia has recently taken over the role, with China being the main driver. Research gaps within this field are also identified. This review can serve as basis for scholars in advancing the theoretical understanding of the reliability impacts of energy storage systems and in addressing the gaps within this field.

Summary
In the electric utility industry, power outages are the main concern because consumers expect a continuously ready supply throughout the year. This ready supply is the ’reliability’ of a power system in providing adequate output to consumers, as discussed in [1]. Several studies have provoked discussions about the consequences of power interruptions on consumers. Distribution systems have generally grown in an unplanned manner, thereby resulting in substantial technical and commercial losses and poor power quality. Other reasons include the lack of efficient tools for operational planning, which leads to increasing system losses [2]. A practical manner of reducing major power interruptions is increasing the reliability of power systems
