Objectives: The main objective function is to increase the Generation Companies profit and reduce the GHG gas emission of the thermal generating units. Methods/Analysis: During the most recent few centuries, emission control has become a very big problem of worlds concern due to the frequently increasing pollution of earth’s atmosphere. In order to reach the emission control in this paper the Improved Bacterial Foraging Algorithm (IBFA) is proposed. The Bacterial Foraging Algorithm is formed by foraging behavior of E-coli Bacteria in the human intestine. But the BF algorithm leads to some convergence problem while solving the large problems. So for improving the performance of the large problems the new integer coded Improved Bacterial Foraging Algorithm is proposed. Findings: The proposed method is implemented to the IEEE 39 bus10 unit system with one day time period. This proposed algorithm is simulated using MATLAB software and the output results are compared with traditional Unit Commitment Method. Novelty/Improvement: The restructuring of electric power industry is used to reform the electric supply industry. The generation scheduling of thermal generating units in deregulated environment is named as Profit Based Unit Commitment. In PBUC problem the normal Demand constraint is changed to modified power demand constraint to increase the GENeration Companies (GENCO) profit.Keywords

Objectives: The objective of this paper is to decide the startup and shut down status of thermal generating units to meet the fluctuating load over a limited period at a lowest cost and also with lowest emission. Methods/Analysis: This paper presents Shuffled Frog Leaping Algorithm to explain short term Unit Commitment Problem solution with regard to Emission limitation and Prohibited Operating Zone (POZ) constraint. Findings: Fuel cost savings can be obtained by proper commitment of the available generating units. The total operating cost includes both the fuel cost and cost associated with the startup, shut down and maintenance of units. A variety of constraints like spinning reserve, generation limit constraint, minimum up time, minimum down time, system power balance and response rate constraints like ramp up constraint, ramp down constraint and prohibited operating zone constraints are considered for investigation. Novelty /Improvement: The problem is solved using an integer coded Shuffled Frog Leaping Algorithm which offers a practical unit commitment problem. A MATLAB code has been developed to explain the unit commitment problem using SFLA. The results are extensively validated for standard IEEE 39 bus with 10 units system. The results obtained are compared with existing method.Keywords

Objectives: The main objective of this paper is smoothening of the power fluctuation of a variable speed PMSG wind generator with the help of Energy Capacitor System (ECS). ECS consists of a voltage source inverter, dc-dc converter and an ultra-capacitor bank including their control strategies. Methods/Analysis: In this paper two back-to-back voltage source Insulated Gate Biopolar Transistor (IGBT) converters controlled through highly efficient variable frequency drive control method is considered. By using this method, efficiency of wind farm can be improved and voltage regulation for interconnecting the wind farm with grid can be achieved. Findings: Recent application of power electronic devices and scaling up of MegaWatt (MW) wind turbines, Low-speed high torque Permanent Magnet Synchronous Generator (PMSG) has become the ultimate choice for wind power extraction. At present, a commercial PMSG based wind generator primarily makes use of a rectifier followed by an IGBT converter. Novelty /Improvement: The real power reference for ECS is generated accurately. Simulation is carried out through MATLAB/SIMULINK.Keywords
