A burning concern of the 21st century is that conventional energy sources are depleting. Thus, it has become a necessity to find alternative power generating sources. Having considered the speedy development of electronic devices, the need for power has never been greater. Each day, people spend more time on electronics but are often found to be in difficult situations with limited battery charge. This research cell investigates the current energy harvesting and storage elements and systems both for off grid and on grid system and tries to discover an innovative approach towards finding a cost-effective and feasible layout for off-grid storage.
This paper provides a platform for a novel innovative approach towards an off-grid Supercapacitor based battery charging hybrid energy harvesting system for low speed Vertical Axis Wind Turbine (VAWT). 3-Phase Permanent Magnet Synchronous Generator (PMSG) was chosen for its low maintenance cost, light weight and less complicated design. Simulation was carried for optimized design and a 200W 12V 16 Pole PMSG attached to a VAWT of 14.5m radius and 60cm of height was sent for fabrication with Maglev implementation (Magnetic Levitation). Upon arrival, the optimized system is implemented into the energy harvesting circuit and field testing is carried to observe the performance. Under wind speed range of 3-5m/s, the energy harvesting circuit showed better efficiency in charging battery in all aspects comparing to direct charging of battery regardless of with or without converter. Based on analysis and results carried out in this thesis, all feasibility studies and information were provided for the next barrier.
