Grid Integration of Hybrid Generation for an Alternative Energy Power System with Improved Power Quality

As the requirement for energy rises and with the extinction of non-renewable energy resources, consumption of renewable energy resources have been trending. Various sources of renewable energy giving to current energy requirement consist of water, wind, solar energy. As a result, the quick advances of power electronic systems the formation of electricity from wind and photovoltaic energy sources has improved considerably. The act of the wind/PV hybrid system is considered under distinct grid perturbation conditions in this study. In this paper, the act of the wind/PV hybrid system is considered under different grid perturbation conditions. Based on the level solid oxide fuel cell (SOFC) dynamic model for optimization method was used to establish the maximum electrical efficiency of the grid-connected SOFC to the constraints of fuel consumption factor, stack temperature and output active power. Power quality is one of a major constraint in power system transmission and distribution. This project gives an idea on effective control of PV/Wind hybrid power generation scheme for standalone applications. This system consists of PV/wind hybrid energy system, boost dc-dc converter, a three phase DC to AC converter, PWM controller and nonlinear load. The boost converter can supply power to the load depending on the source of availability. A synthesized AC output voltage is produced by appropriately controlling the switches using PWM technique using average power control to control active and reactive power fed to the load the operating setting of the grid-connected SOFC was obtained by predicting the difficulty considering the power consumed by the air compressor. With the average operating conditions of the maximum efficiency operation obtained at unusual active power output levels, a hierarchical load tracking control scheme for the grid-connected SOFC was proposed to appreciate the maximum electrical efficiency utility with the load high temperature bounded. Generation and utilization of electricity will be takes place at reasonable cost. This proposed concept deals with the generation of electricity by using two sources which combines which leads to create electricity with reasonable cost and lacking damages in the proposed system.
