It is known the performance of a gas turbine (GT) has strong dependence of climate conditions. A suitable solution to minimize this negative effect is to raise inlet turbine temperature and reduce temperature of inlet air to GT com- pressor. Combined cycles gas turbines (CCGT) are a lot used to acquire a high-efficiency power plant. Increases the peak compression ratio has been proposed to improve the combined-cycle gas-turbine performance. The code of the performance model for CCGT power plant was developed utilizing the MATLAB software. The simulating results show that the overall efficiency increases with the increase of the peak compression ratio. The total power output increases with the increase of the peak compression ratio. The peak overall efficiency occurs at the higher compression ratio with low ambient tempera- ture and higher turbine inlet temperature. The overall thermal efficiencies for CCGT are higher compared to gas-turbine plants.

The conception and assembly of an experimental Hybrid Electric Vehicle based on the combination of human energy contribution and photovoltaic solar energy is presented in this manuscript. The vehicle has a battery for storing the energy provided by both systems. The application's aim is to achieve the lowest possible energy consumption for the vehi- cle's movement, with photovoltaic modules as the main electricity source. The development of the solar vehicle was moti- vated by a Latin-American solar vehicles race about 1000km across the Atacama Desert in Chile, South America. The main constructive aspects, energy issues and experimental results are presented.

Experiments were conducted to determine the heat transfer characteristics for fully developed flow of air and water flowing in alternate corrugated ducts. The test section was formed by three identical corrugated channels having corrugation angle of 30 o with cold air flowing in the middle one and hot water equally divided in the adjacent channels. Sinusoidal wavy arcs connected with tangential flat portions make the said corrugation angle with transverse direction. The Reynolds number based on hydraulic diameter varied from 750 to 3200 for water and from 566 to 2265 for air by changing the mass flow rate of the two fluids. The Prandtl numbers were approximately constant at 2.55 for water and 0.7 for air. The various correlations obtained are Num=0.247Re 0.83 and Num=0.409Re 0.57 for water and air, respectively and f = 2.014Re -0.12 for air channel.

A novel on-axis general sun-tracking formula has been derived and integrated into an open-loop azimuth-elevation sun-tracking system for improving the tracking accuracy. The installation defect of a 25 m2 solar concentrator prototype has induced significant sun-tracking errors, range from 12.12 to 17.54 mrad. With the use of CCD camera for recording the solar image, three misaligned angles from ideal azimuth-elevation axes have been determined and corrected by changing of the general formula parameters’ values to better the tracking accuracy to 2.99 mrad, which reach the encoder resolution limit of 4.13 mrad. Further fine-tuning has been made to attain the tracking accuracy up to 0.96 mrad, by including the motor step count, 1.64 × 10–4°/step, which is beyond the encoder resolution. The general formula has been demonstrated to be capable of achieving reasonably high tracking accuracy cost effectively without complicated sun-tracking solutions.

In order to have stable and improve efficiency in power supply, there is need to analyse and understand the complex interrelated factors affecting the efficiency and stability of power supply. The factors that affect the efficacy and stability of power supply in any developing country/region could be classified as follows: government policy; economy factor; natural factor; society/community factor; effective energy management; skilled personnel; efficient technology and security factor. All these factors mentioned above have direct or indirect influence on the stability and efficiency of power supply. Various numbers of complicating factors that can prevent restructuring of energy sector to create electricity market that can improve efficiency of power supply in Nigeria are analysed. Suggestions of steps or actions that should be taken into consideration before proposing solutions to some of the problems of power sector are also highlighted in this paper. Stable and efficient power supply in any nation is the key to economic growth in that nation. Nigeria is facing enormous technical, management and economic problems in energy sector that calls for an urgent special approach. In order to find engineering/management solutions to power system problems, it is inevitable to carry out technical and management analysis of interrelated factors that have great impact on the smooth operation of the energy sector as a whole. It is important to note that the problems affecting energy sector in developing countries differ from the problems that influence the same energy sector in developed countries. In view of these differences, it will be difficult to achieve economic efficiency in developing countries, following the same pattern of restructuring and deregulation of energy sector in developed countries.

An experimental investigation on a solar still with lauric acid as phase change material (PCM) is carried out to examine the effect of both the mass of PCM and basin water on the daily distillate productivity and efficiency of the system under outdoor condition. Basic energy balance equations are written to predict the water and glass temperatures, daily distillate productivity and instantaneous efficiency of the single slope solar distillation system with PCM. It is found that the higher mass of PCM with lower mass of water in solar still basin significantly increases the daily productivity and the efficiency. Therefore, the distillate productivity at night and on day for solar still with PCM increased by 127% and 30-35% respectively than without PCM one. Shukla et al. approach of the use of inner glass cover temperature for productivity prediction which has also been investigated, and the prediction shows relatively better agreement with the experimental data than outer glass cover temperature.

Corncobs are generated from maize (Zea mays). The residue is usually dumped and flared on the farms, where it constitutes fire, environmental and health hazards. Corncobs are potential feedstock for energy generation. This work investigated densification characteristics of corncobs. Corncobs were collected from farm dump at a moisture content of 10.96 dry bases, reduced and sieved into three particle sizes S1, S2; and S3. Starch mutillage of 20, 25, and 30 % by weight of the residue was added as binder. The briquettes were produced using briquetting machine at pressures of 2.1, 4.2 and 6.6 MPa. The ASAE standard methods were used to determine the moisture contents and densities of the milled residues and briquettes. The compaction, density and relaxation ratios as well as percentage expansion of the briquettes were determined using ASAE standard methods. The mean moisture content of the corncob residue was 9.64 %, while that of relaxed briquettes was 7.46%. The value of bulk densities of the residue materials was 50.32 kg/m3. The initial, maximum and relaxed densities ranged from 151-235 kg/m3; 533-981kg/m3 and 307-417kg/m3 respectively. The compaction ratio ranged from 2.27 to 6.50. The maximum percentage volume reduction was 626%, while the axial and lateral relaxations were in the range of 0.62-9.85% and 0.64-3.63 respectively. The briquettes were stable up to six months. For the three processing parameters examined, binder ratio B1, particle size S3 and pressure P3 exhibited most positive attributes.

Various technical limitations of generating units and ancillary services requirements have more complicated the power generation control and operation. This paper introduces a novel methodology for day-ahead unit commitment, which is a crucial challenge in restructured power systems, considering primary frequency control reserve. In addition, also spinning reserve uncertainty as a practical constraint has been taken into account. In this paper, we formulate and solve simultaneous scheduling of energy and primary reserve as a mixed integer non linear programming problem that simultaneously accounts aforementioned constraints. In proposed formulation, system frequency is allowed to fall from nominal value to a critical specified limit. Finally, the proposed approach is implemented to the scheduling of a 17-unit isolated power system over 24-hours. Case studies and numerical results present significant outcomes and verify the robustness of the proposed method, while it creates a schedule consistent with the primary frequency control and spinning reserve uncertainty.

Multi objective optimal reactive power flow considering FACTS technology is becoming one of the most important issue in power system planning and control. This paper presents a new variant of particle swarm algorithm with time varying acceleration coefficients (TVAC) to solve multi objective optimal reactive power flow (MOORPF) (power loss minimization and voltage deviation). The proposed algorithm is used to adjust dynamically the parameters setting of Thyristor controlled series capacitor (TCSC) in coordination with voltages of generating units. This study is implemented on the standard IEEE 30-Bus system and the results are compared with other evolutionary programs such as simple genetic algorithm (SGA) and the simple particle swarm algorithm (SPSO). Simulation results confirm robustness of this new variant based PSO in term of solution quality and convergence time.

The wind energy conversion systems when operate in weak grid or in isolated mode may cause power quality problems due to variation in wind speed and other circuit conditions. To improve the power quality of wind generation system a wind-diesel hybrid system is proposed in this paper. The power quality of the system is improved by controlling the excitation and input power of the synchronous generator. The PID controller is used in input power controller. A new optimization technique i.e. bacteria foraging optimization to optimize the PID controller gains is used to improve the power quality of the proposed system.
