“…The coal mass flow rate and the turbine governor valve are selected as the manipulated variables (MVs). These four variables are in the upper most layer of CFPP control [37]. Regarding the PCC system control, the CO2 capture level and the re-boiler temperature are considered as the most central CVs [24]- [31].…”

Solvent-based post-combustion CO2 capture (PCC) provides a promising technology for the CO2 removal of coal-fired power plant (CFPP). However, there are strong interactions between the CFPP and the PCC system, which makes it challenging to attain a good control for the integrated plant. The PCC system requires extraction of large amounts of steam from the intermediate/low pressure steam turbine to provide heat for solvent regeneration, which will reduce power generation. Wide-range load variation of power plant will cause strong fluctuation of the flue gas flow and brings in a significant impact on the PCC system. To overcome these issues, this paper presents a reinforced coordinated control scheme for the integrated CFPP-PCC system based on the investigation of the overall plant dynamic behavior. Two model predictive controllers are developed for the CFPP and PCC plants respectively, in which the steam flow rate to re-boiler and the flue-gas flow rate are considered as feed-forward signals to link the two systems together. Three operating modes are considered for designing the coordinated control system, which are: 1) normal operating mode; 2) rapid power load change mode; and 3) strict carbon capture mode. The proposed coordinated controller can enhance the overall performance of the CFPP-PCC plant and achieve a flexible trade-off between power generation and CO2 reduction. Simulation results on a small-scale subcritical CFPP-PCC plant developed on gCCS demonstrates the effectiveness of the proposed controller.

“…One of converting method is the steam power system or Rankine cycle. The Rankine cycle have range thermal efficiency of 33% to 45% but it still depended on main steam pressure, main steam temperature and fuel used [1] [2]. The range of operation pressure and temperature of steam power plant of 10 kg/cm 2 to critical pressure and 250 0 C to 650 0 C respectively [3].…”

Power plants using steam are a very popular system today. To develop a construction of power plant system requires an accurate analysis in determining operating parameters as expected. Designing with manual calculations certainly requires a very long time. One of faster method use a thermodynamic simulation system such as a Gate Cycle. The goal of this research was to simulate a steam power plant to produce 25 MW net electric power and to investigate the effect of an increasing of main steam temperature, main steam pressure and condenser pressure on electrical power and thermal efficiency. The simulation was done using the main input data of simulation were tempe rature of 535 0 C, pressure of 89 bar, condenser pressure of 0.084 bar and heating value of low rank coal of 3800 kcal/kg. The main steam temperature was varied of 515; 535; 555 and 575 0 C. The main steam pressure was varied of 79; 89; 99 and 120 bar, The condenser pressure was varied at 0.064; 0.074; 0.084 and 0.094 bar. The simulation results showed the net electric power produced of 25.8 MW on the main input data. An increasing of the main steam temperature and the main steam pressure would increase the net electrical power and the thermal efficiency but an increasing of condenser pressure would decrease the net electrical power and the thermal efficiency

Summary Algeria is in a region with an enormous potential of solar energy for power generation. However, photovoltaic (PV) power plants have not yet been developed sufficiently in the country, and its applications such as PV pumping, solar distillation, and solar heating. The main problem is the high maintenance, operating costs, fossil‐fuel transportation, and CO2 emission of Bordj Badji Mokhtar's (BBM's) diesel power plant that exhibits a noteworthy issue in south Algeria. This paper presents the results of a theoretical and experimental study for PV/diesel hybrid energy system (HES) considering the load demand profile and the solar radiation in isolated area of south Algeria. Suggested hybridization based on a renewable energy with a view to an improved environment is promising. Study results show the performance of PV/diesel system based on solar radiation. The experiment load curve in this typical area may conduct the diesel generator to operate at 60% to 70% of its nominal power with less fuel consumption, and it has been verified during this study that the implementation of a PV/diesel hybrid system is efficient for higher load and higher solar radiation. Results and discussions are encouraging considering less emission of greenhouse gases and less storage of fuel, which drives the government to draw a political arrangement for the improvement of cleaner forms of electricity generation.
