The ever-increasing demand for electricity has posed several challenges such as reliability, security, economic and
environmental factors etc. in front of the current electric power system. A smart grid concept is a key solution to these issues because
it uses digital technology to revolutionize the conventional electric power system, although the concept of the smart grid is not yet
completely defined. The electrical power system contains three sections, namely generation, transmission, and distribution. This
paper discusses the important aspects and concepts of the reliability in the distribution section. Since reliability in distribution
systems (DSs) has always been a major concern for utility providers, we have surveyed existing reliability methodologies along with
Monte Carlo (MC) approach and recent research works to improve reliability and calculate reliability indices. The integration of
renewable energy sources (RESs), energy storage systems (ESSs) and distributed generation (DG) into grid solutions is also
considered in this paper as they can provide reliable power to consumers and reduce electricity losses, reliance on centralized plants
as well as the environmental impacts. Furthermore, this paper highlights key features in tabulated forms for comparative study and
future challenges.
