Abstract
Most of the Telecom towers in India are located at remote areas where supplies for these towers are needed to be supplied by using Diesel generators mostly. These system are highly costly and emission of green house gases is evitable thus by using renewable resources the demand for the towers can be satisfied partially so that the cost of operation of telecom towers can be reduced and emission of green house gases and harmful gases can be reduced to an extent. A hybrid generation system consist photovoltaic (PV), wind turbine (WT) and Battery is presented to supply stable power to rural residential loads. DC/DC converters are used to control the power flow to the load and Maximum Power Point Tracker (MPPT) is used for maximum power extraction from the solar photovoltaic systems and wind turbine. To compensate power fluctuation of renewable energy MPPT method is used. When PV and WT generate power is lower than demand power, the Battery is controlled to discharge power to complete the difference of supply and demand power. If PV and WT generate power is higher than demand power, the Battery is controlled to charge power. The system was simulated by using MATLAB/Simulink and a control system is designed using ARM Microcontroller for energy management. The simulation results show the proposed system can compensate power fluctuation
