Summary: Latent heat thermal storage based on phase change material (PCM) in shell-and-tube heat exchangers can reduce power consumption of air conditioning systems. By optimizing the charging/discharging time of PCM and the operating conditions of the chiller, better performance can be achieved. Experimental validation shows that the optimal solution leads to a reduction in the inlet temperature by 1.25℃ and a maximum utilization of PCM by 40% of the initial amount. Further optimization results in a shell diameter reduction of 12 cm to exploit 72% of the PCM potential.

Summary: Despite the positive effects of renewable energy sources on decarbonizing energy systems, their intermittent and non-programmable nature can have a significant impact on the short-term scheduling of distributed energy resources (DER) in smart grids. This paper presents a comprehensive tool for generating scenario profiles of solar irradiance using historical data. The tool is particularly useful for stochastic operation optimization of DER systems, allowing the generation of plausible scenarios while reducing computational efforts. The application of the tool to a numerical case study shows that it can generate realistic solar irradiance profiles for DER optimization, considering fluctuating and plausible patterns. A sensitivity analysis evaluates the impact of key parameters on the generated profiles, providing guidance for defining scenarios with specific characteristics.
