Abstract Today, using new energy storage systems for peak shaving and load leveling with the approach of maximizing the efficiency of energy systems is inevitable. In the present study, a cogeneration integrated structure of power and cooling using liquefied natural gas regasification and solar collectors is developed and analyzed. In this regard, the purposes can be achieved by producing liquid air at an off-peak time and storing it as a cryogenic energy storage system and recovering it on-peak time. This new integrated structure generates 11.66 MW power and 4.502 MW cooling at the on-peak time. A Kalina-based combined cooling and power cycle and a gas turbine power generation unit are used to generate power from liquid air. Phase change material is used to store the heat from the compressed air entering the liquefaction stage (at the off-peak time) and recovering it at the on-peak time as the heat source of the Kalina cycle. Also, the solar parabolic trough collector provided with Zahedan climatic conditions the heat required for the direct expansion section. The electrical storage, round-trip, energy storage, and exergy efficiencies of the proposed energy storage system are 57.62%, 45.44%, 79.87%, and 40.17%, respectively. The most exergy destruction belongs to the heat exchangers section, which accounts for 50.85% of the total exergy destruction. One of the important results of the parametric study is the increase of round-trip and electrical storage efficiencies up to 47.59% and 61.60%, respectively, by minimizing the pressure of the inlet air to the liquefaction stage while maximizing the pressure of the liquid air inlet to the power generation stage.
