Most of the renewables are intermittent, to have reliable power the renewables have to be conditioned before injecting into the utility grid. The DC-DC converters are perfect power electronic devices for conditioning the renewables. The single ended primary inductor converter (SEPIC) performs the conditioning with a very high voltage transfer gain and minimum ripples. The maximum power extraction from the PV panels is required for providing good quality DC power. Intelligent controllers can make use of optimization techniques. The particle swarm optimization (PSO) technique can optimize the controller to extract the maximum power. The SEPIC converter duty variation is optimized and a comparative analysis with the Buck-Boost converter is done in a MATLAB/Simulink environment. The proposed SEPIC converter system performed well by improving the power tracking by 40% and the system has been analysed in a battery charging environment.

Photo Voltaic (PV) integrated UPQC compensates for real (P) and reactive power (Q). PV-UPQC system consists of back to back series and shunt compensators interlinked by a common DC link capacitor powered by the photovoltaic system. The reactive power compensation is achieved by shunt compensator of PV-UPQC system. The voltage fluctuations like voltage sag/swell are compensated by the series compensator.

This co-ordinated ED problem is solved by the application of Phenotypic Evolutionary Programming (PhEP) with correlated mutation. In the recent past it has become necessary to utilize renewable energy generation as an alternative for thermal energy power generation due to its depletion nature. This paper considers wind power generation as renewable generation. The main advantage of wind power generation is that it produces cleaner electrical power without introducing harmful environmental pollutants. The incorporation of wind generation into conventional ED problem modifies to a higher degree of non-linear problem. Hence this paper attempts to solve this wind integrated ED problem through PhEP algorithm with correlated mutation. The proposed algorithm has been tested with standard 3, 13 and 40 unit test systems and implemented through matlab.

The introduction of many DC-DC topologies has led to different functionality in power conditioning. Luo converter is one such DC-DC converter that is embedded by the voltage-lift techniques. The power transfer efficiency and the output voltage of Luo converter are limited by the limits on the parasitic elements in DC-DC converters. The Negative Output Luo converter is one wherein the DC power conditioning is done in the second quadrant with minimum passive elements. This helps in achieving reduced ripples, and high voltage transfer gain. The DC input can be harnessed from renewable energy resources like Solar energy through Photo-voltaic panels. The PV integrated Negative Output Luo converter is backed up by a Maximum Power Point Tracker with Perturb and Observe algorithm to extract maximum power at varying irradiance. In this paper, the Negative Output Luo converter is designed to control the speed of high power-to-weight ratio motors like BLDC motor. The characteristics of the proposed system under various irradiance have been analysed and reported.
