| Summary: | This thesis presents an approach of hybrid system implementation between Photovoltaic
and ocean waves. These renewable energy sources are abundant, clean and beneficial
compared to existing fossil fuel. Common method of extracting energy from these
sources normally utilized a single energy source for energy production. Through hybrid
system, two or more sources integration is possible. Merging of multiples energy
sources will complement and support any inadequacy attribute accompanying these
sources. However, system complexity will increase as source increases resulting in
complicated system. Thus a proper controlling method is required for effective source
management. Therefore, this research was initiated to develop a controller for two
system harvester modules, Photovoltaic and wave energy converter for hybrid power
system. The controller should fully exploit energy potential characteristic by harnessing
it to the maximum. This research provides an effective method of harvesting
Photovoltaic and ocean waves. Photovoltaic source is dependable toward sun intensity
while the ocean waves’ intermittent energy is unsuitable through conventional
harvesting method. The established controller will integrate Photovoltaic and ocean
waves and compensate power fluctuations. Proper integration was successfully executed
through buck and boost converter module. The wave energy converter module was
developed using ratchet mechanism and the generator unit was extracted from mini
ceiling fan motor. An additional monitoring system was added and performs wireless
transmission to operator. The developed Photovoltaic and Wave Energy Converter
(WEC) sources progress rapidly with average power produced are 76.91mW and
82.237W respectively. The proposed controller excels in performance and produce
effective hybrid energy management with measured with power extraction efficiency at
58%. The hybrid system was successfully executed within the prescribe scope
boundaries. |
