In this paper, the mitigation of the adverse effects of pulsed power loads on the microgrid systems is considered. In microgrid power systems, pulsed loads are particularly problematic since the total system inertia is finite. Examples include ships and aircraft with high power radars, pulsed weapons, and electromagnetic launch and recovery systems. In the se systems, energy is collected from the system over a finite time period, locally stored, and then rapidly utilized. Herein, a new strategy, Profile Based Control, to accommodate these loads is presented. This strategy is based on identifying the optimal charging profile. Also, later onwards, this new strategy is combined with load coordination. And it is found that current waveform is more smoothened and the output power is improved from 2489W to 3712W. 2014-12-28T00:00:00Z http://hdl.handle.net/123456789/6642 Comparative Study between Conventional Booster and High Step up DC-DC Converter for Low Power PV Edwin Basil Lal Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–dc boost converter. The converter is simulated with low dc voltage input for low power applications. A 15V input voltage, 200V output voltage, and 100W output power prototype circuit of the proposed converter has been implemented. The PV model implemented with MPPT algorithm using Perturb and Observe method is used with the boost converter to get the PV module. The PV module with booster developed will give a voltage gain range of 10-12 times the input voltage. The Comparative study between the normal booster PV model and high gain PV model is done. The simulation results are presented in this paper to verify the theoretical analysis by using software MATLAB. 2014-12-28T00:00:00Z http://hdl.handle.net/123456789/6640 Modularized Combination Of Buck Boost And Cuk Converter For Electric Vehicle Lead Acid Battery Cell Voltage Equalization With Feedback Cicy Mary Mathew The need for a voltage equalizer is principally due to the differences in cell chemistry, temperature gradients along the battery string and the ages of the batteries. Therefore maintaining the charge level on each battery becomes important. This paper analyses the new topology which combines the buck-boost converter and the Cuk converter together which would use only N number of switches for N number of battery in contrast to the (2N-1) switches used by either buck-boost converter or cuk converter. The converter topologies that is a combination of buck-boost and cuk converter without feedback and with feedback are simulated using MATLAB/SIMULINK R2010a. The simulation results show that there is an increase in the rate of equalisation of about 10% with the use of feedback. 2014-12-28T00:00:00Z http://hdl.handle.net/123456789/6638 Power Quality Improvement With Series and Shunt Compensation Arya Raveendran 2014-12-28T00:00:00Z
