NICOP - Standalone Maximum Power Point Tracking Controller for Partially Shaded Photovoltaic Array under Fast Varying Solar Intensity
Abstract
The use of photovoltaic (PV) system to replace the conventional fossil fuel electricity generationsystem has been greatly increased" in recent years. But, the efficiency of the PV system is highlydepended on the weather condition such as solar intensity. Under di""fferent solar intensity, theoutput power from the PV system varies. The PV array operate under partial shading condition iseven wo""rst in efficiency. Thus, this research work is aim to design a maximum power pointtracking (MPPT) controller which is required in o"rder to ensure the maximum power is alwaysextracted from the PV system under any condition especially under partial shading. The re"searchcan be divided into two main area which are the hardware and software. In hardware part, asuitable DC-DC converter has to be"" designed and implemented. Then, themicrocontroller/embedded system will be used to implement the software of MPPT algorithmsin th""e DC-DC converter to track for the maximum power point of the PV system. With the help ofthe MPPT controller, the efficiency of the" PV system is able to be increased greatly and can beimplemented as standalone PV system with the help of battery storage.Naval & Scientific SignificanceThe objective of this research project is to improve the efficiency of the PV system especiallyduring partially shaded condition. The efficiency of the PV module is an important issue as thehigh investment cost required to install the PV" system. Thus, the user would like to ensure theefficiency of the PV system always stay as high as possible. With conventional algo""rithm, theefficiency is unable to be ensured. The application of optimization algorithm in the PV system willgreatly improve the f""easibility of the system against the variation in the solar intensity.As the navy is operating in the remote area, the devices requ""ire standalone power supply and PVsystem is one of the suitable power source. By using the PV system, the navy do not need to worry"about the power generation problem in remote area. The PV system can be easily installed in theremote operating location and thus" no grid transmission line is required. With battery storage, allthe equipment require power supply should be able to obtain power"" even during night time.At the end of this project, the efficiency of PV system during partially shaded condition will beimproved."" Apart from that, the response time of the PV system against the variation in the solarintensity will be improved by using the opti""mization algorithm as the MPPT technique. In thefuture, the algorithm can be implemented in the miniature PV system which embedded" into thedevices. At the end the army will be able to move easily with power source on their equipment.Scientific Relevance:The r"esearch paper output from the research project will be at least 1 international conferencepaper, 2 technical journal paper and 1 re"view journal paper publication. The journal output ishighly depended on the finding of the research project.We plan to submit the" journal to IEEE Transaction on Industrial Electronics, IEEE Transactionson Sustainable Energy or Renewable and Sustainable Energy" Reviews.
