The role of cool thermal energy storage (CTES) in the integration of renewable energy sources (RES) and peak load reduction

Cool Thermal Energy Storage (CTES) may play an important role in the management of peak loads and solve the intermittency problem of RES, especially when cooling storage is integrated into district cooling systems. A simple mathematical model of a system with integrated RES and CTES has been developed. Hourly system analyses have been conducted for one building, a group of buildings connected to the district cooling system and a region represented by a mixture of different demands for cool thermal energy. This paper also includes the results for the overall energy efficiency, cost effectiveness and environmental impact of the systems analysed.
