Dynamic Power Generation And Control From Hybrid Wind Solar And Foot Step Stand Alone System

Dynamic Power Generation And Control From Hybrid Wind Solar And Foot Step Stand Alone System
V.Prabhakaran, S.Pavithra, Muppidi Pavan Kumar, K.S.Mohammed Gohar Latheef::The renewable energy source such as wind is available in remote areas. However, power from the wind is fluctuating and weather dependent. Therefore, they can be used as a standalone power supply source for an isolated community. This paper aims to implement hybrid power generation in which each power generating system will be standalone. In this paper, a complete analytical methodology has been presented for three power source. Technical optimization is enhanced by adding the Battery back up for the storage of photovoltaic power where the electrical energy gained is stored in the battery and when the light intensity is low, energy is consumed from the battery. Next Pitch angle is added to provide 360 degree movement for the PV system. So the PV system can sense the light intensity using LDR (Light Depending Resistor) sensor and based on the intensity level the stepper motor moves the system to the direction. For Economic optimality voltage monitoring circuit is used to monitor the voltage gained by the PV system in each direction. Next the Foot step is designed mechanically i.e., suspension system will be placed in each steps or plain surface and when the footwear is pressed the system will move ups and down to create the mechanical energy. Chain track will be connected between the gearing system and DC motor. When it is pressed the DC motor will start rotating and produce the electric power which is stored in the battery for particular load to be operated. The Voltage monitoring circuit is placed to monitor the voltage level of the battery and transmit the signal to the controller part that would indicate the level of battery. The last phase will wind power Generation generated by wind alternator. Power generated by each source is stored in the battery and power is analyzed. When the voltage generated by any of the source is not up to the set point other source energy must be compensated.
