I want to share on this web log my latest published work on MPPT method of solar PV module. The paper is published in an ISI indexed journal of American Institute of Physics (AIP). The journal name is Journal of Renewable and Sustainable Energy (JRSE) which is devoted for the research in the field of renewable energy. I will briefly introduce my work here and later on i will present my views about my experience in publishing in JRSE.



Paper Title

An intelligent control strategy of fractional short circuit current maximum power point tracking technique for photovoltaic applications
Authors
Abstract 
This paper presents an improved Fractional Short Circuit Current (FSCC) Maximum Power Point Tracking (MPPT) technique in which an additional control loop is used to find the proper moment to measure the SCC. The target is to reduce the power losses in MPPT process that occur as a result of intermittent time based short circuit current measurements. The proposed modification enables the conventional FSCC MPPT to decide intelligently about themeasurement of SCC thus reduces the number of times the photovoltaic (PV) module is isolated from the load. Although number of algorithms for tracking MPPT has been reported, the proposed method suits well for low cost PV applications. A Matlab/Simulink based model is employed to test the functional abilities of the proposed method. The comparison of the proposed method and conventional time based FSCC method is also presented in the simulation analysis. Finally, a 130 W prototype based on the dSPACE DS1104 controller and experimental results are presented to verify the effectiveness of the proposed method. The technique is verified under uniform shading conditions. The results show satisfactory performance against test conditions.
In this paper, we have proposed an improvement in offline MPPT technique. The proposed improvement can be applied to either the FOCV or to the FSCC. Simulation as well as experimentation has been performed for FSCC MPPT. The proposed modification intelligently calculates the right time to isolate the PV panel, thus does not need the time based measurement of short circuit current. Following are the advantages of the proposed method:

• The modified control methodology eliminates the necessity of any irradiance sensor.
• Intelligent detection of change in irradiation.
• A cost effective solution for low cost solar PV applications without much compromise on energy loss.

This proposed algorithm in off-line MPPT techniques as a whole will enrich the research in the field of PV systems.
