This paper provides an overview of local power systems based on renewable energy sources (RES) used to create power  supply systems for consumers located in remote and hard-to-reach areas. Regulatory documents defining the terms "Smart Grid" , "Local Power System" internationally and in the CIS countries are reviewed. An example of creating a hierarchy of an electric
power system is provided using Russia as an example, as well as the experience of creating EPSs in other countries. The components  of the "Smart Grid" concept are presented. In conclusion, taking into account the current state of the electric power industry in the  Republic of Tajikistan, the main objectives for the further consideration and development of local power systems based on RES are  formulated.
Keywords: electric power system, renewable energy sources, local electric power system, smart grids, Smart Grid,  regulatory documents.
