Abstract
This paper deals with the contribution of energy storage system to power system. According to a distribution network parameters there were implemented elements that are very popular and common in power system configuration. For that reason a power network consisted of sources such as wind farm, photovoltaic farm and in specific undesirable condition the distribution network connection as a backup was considered as a power source. Load, in this power system, was considered of constant power. During the simulation, there was implemented energy storage system that compensate the missing power until the specific state of discharge, when the connection to distribution system was implemented. Simulations were realized in Matlab/Simulink environment where 48-hours interval of various states of above mentioned elements cooperation was investigated. Results were analyzed and the recommendations were mentioned in conclusion.
