The optimum pressure for working fluid in feed water heaters of steam power plants
The aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the Rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. Thermal efficiency is defined as a function of unknown variables (fluid pressure and vap...

متن کاملLoad Control Strategies for Electric Water Heaters with Thermal Stratification
This semester project investigates strategies aimed at controlling the aggregate power demand of large groups of domestic electric water heaters. An existing model of a single electric water heater that considers thermal stratification along the height of the hot water tank was tuned and verified using experimental data. The tuned model was then incorporated into an existing model of a water he...
متن کاملAn Efficient Water Flow Control Approach for Water Heaters in Direct Load Control
Tank water heaters (WHs) are present in a prevailing number of European households. Serving as energy buffers WHs have come under the spotlight of various direct load control (DLC) programs over the last few decades. Although DLC has proven to be an efficient measure towards daily peak demand shaving, the payback effect might lead to a new peak in the grid. This payback phenomenon takes place e...
