introduction: mass production of natural enemies has been considered a necessity for biological control programs. most beneficial insects have a relatively short shelf-life, so suppliers do not have a sufficient number of biocontrol agents. the development of storage techniques for biocontrol agents provides flexibility and efficiency in mass production. cold storage by prolonging insect develo...

The integration of renewable wind and pumped storage with thermal power generation allows for dispatch of wind energy by generation companies (GENCOs) interested in participation in energy and ancillary services markets. However, to realize the maximum economic profit, optimal coordination and accounting for reduction in cost for environmental emission is necessary. The goal of this study is to...

A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...

It is important to evaluate whether an ice thermal storage system can operate effectively as the way planned at the design stage. While designing an ice thermal storage system, generally, the thermal storage time is calculated by using rated capacity of refrigerator or the heat exchange capacity of ice-on-coil, and the heating capacity time is calculated by using the average ice melting ability...

The impact of different energy storages on power systems has become more important due to the development of energy storage technologies. This paper optimizes the stochastic scheduling of a wind-based multiple energy system (MES) and evaluates the operation of the proposed system in combination with electrical and thermal demand-response programs and the three-mode CAES (TM-CAES) unit. The prop...

Latent heat storage using phase change materials (PCMs) is one of the most efficient methods to store thermal energy. Therefore, PCM have been applied to increase thermal energy storage capacity of different systems. The use of PCM provides higher heat storage capacity and more isothermal behaviour during charging and discharging compared to sensible heat storage. Moreover, thermal energy stora...

A new composite mesoporous honeycomb material was developed to be a thermal energy storage medium that can contact the functional fluid directly. In our previous study, this honeycombed composite material acted as a promising sorption thermal energy storage medium in an open system, exhibiting a lower regeneration temperature as 80°C, high volumetric heat storage density, and high stability. In...
