This paper introduces an optimization approach to the design of process combined heat and power systems that integrate the thermal profile of the process, an external fossil fuel, and solar energy. A hierarchical design approach is proposed to stage the implementation of steady-state and dynamic calculations. Initially, energy integration is used to identify minimum heating and cooling utility targets. Next, a genetic algorithm approach is employed to optimize the external heating load and generated power of the cogeneration system that includes a steam Rankine cycle. Another loop is used to optimize the flowrate, temperature, and pressure of the steam entering and exiting the turbine. A multi period optimization approach is developed to account for the diurnal variability of solar energy. Direct usage of collected solar energy is considered along with the option of thermal storage and dispatch. The solution of this mixed integer nonlinear program determines the optimal mix of energy throughout the year. A case study for a petrochemical plant in Jeddah, Saudi Arabia was solved to illustrate the applicability of the devised approach.
In view of the variances in episode sun based force, source power additionally changes over the long run (e.g., on an hourly premise or occasionally). In the event that there is a requirement for a steady electrical plug, there are alternatives towards a consistent state yield of the framework. This work is focused on the advancement of efficient plan techniques for two sun based force age systems. The first is coordination of petroleum derivative with the close planetary system to give a pay impact (power reinforcement to enhance the force primary source from sunlight based energy). The second is the utilization of warm energy stockpiling (TES) frameworks to save sun based energy in a warm structure and use it when sunlight based information diminishes. A typical TES setup is the two-tank framework which permits the utilization of the gatherer heat move liquid (HTF) as a putting away medium. For the two tanks, one tank has the hot medium (e.g., a liquid salt) and the second has the cool stockpiling media. In particular, the accompanying plan difficulties are tended to: 1. What is the ideal blend of energy structures to be provided to the cycle? 2. What are the ideal situation and mix mode to convey the chosen energy structures? By what method would it be advisable for them to be coordinated among themselves and with the cycle? 3. What is the ideal plan of the energy frameworks? 4. What is the ideal unique methodology for working the different energy frameworks? 5. What is the achievability of utilizing warm energy stockpiling to this ideal petroleum derivative framework? The created strategy incorporates social occasion and age of pertinent sunlight based and climatic information, displaying of the different segments of the sun based, fossil, and force age frameworks, and advancement of a few parts of the cross breed framework. A contextual investigation is tackled to exhibit the adequacy and appropriateness of the contrived strategy.
