“…Our recent proposal for PIN diode modeling [27] has been generalized to include the various current transport mechanisms that could coexist in real solar cells with series and shunt losses. The distinctive and most valuable feature of the presently proposed alternative approach is that the current may be expressed as an explicit analytic function of the applied terminal voltage.…”

Classical analyses of various conventional solar cell models are examined. They are unified through the separation of their linear and nonlinear components and the application of Thevenin's theorem to the linear terms. An explicit multiexponential model with series and shunt resistances is proposed as an alternative to conventional implicit multiexponential models commonly used to describe significant parallel conduction mechanisms in real solar cells. The proposed model is better suited than conventional models for repetitive simulation applications because of its inherently higher computational efficiency. Its explicit nature is a very useful feature for direct analytic differentiation and integration. The model's applicability has been assessed by parameter extraction and subsequent playback using synthetic I-V characteristics of a hypothetical solar cell at various illumination levels chosen purely for illustrative purposes.

This paper presents the verification and implementation of non-inverting buck-boost converter in the application of energy-harvesting battery charger which is widely used in multiple power source embedded system. Simplified models for PV and rechargeable battery have been used for theoretical analyzing. Buck and boost topologies have been analyzed to obtain the MPP (Maximum Power Point) under different supply voltages and several Power-Duty cycle curves have been obtained. The combination of the curves verifies the feasibility of the usage of non-inverting buck-boost converter in such application. Hardware circuit is also constructed and the experimental results match the theoretical data precisely.

“…The output voltage is mainly affected by temperature, while the output current is mainly affected by solar irradiation. The characteristic curves of the I PV -V PV and the P PV -V PV are different and nonlinear for different solar radiation and temperature (Patangia et al, 2010;Chatterjee and Keyhani, 2011;Turhan et al, 2013;Yousri et al, 2019). For each ambient condition, there is a typical maximum power point which will change along with the variation of solar radiation and temperature.…”

“…Another approach to develop MPPT controller is to propose a Thevenin equivalent model of PV arrays (Patangia et al, 2010;Chatterjee and Keyhani, 2011;Turhan et al, 2013). In these studies, the error in Thevenin equivalent model of PV arrays can be negligible at the MPP, and this model can be used for analyzing the behavior of the PV arrays (Chatterjee and Keyhani, 2011).…”

Smart grids are considered as key solutions to solve current power security issues. Among these suggestions, microgrid is proposed to integrate distributed generations (DGs) such as photovoltaic (PV) system into the network and the control of DGs output power is getting more attention. The output power of PV arrays with nonlinear characteristics is affected by temperature, solar irradiation and load. Various maximum power point tracking (MPPT) methods for photovoltaic (PV) power systems have been considered and developed to maximize the delivered possible power. In this paper, a modelized photovoltaic source is introduced, based on the Thevenin equivalent circuit. An ordinarily employed solar system model is linearized into simple Thevenin source-resistance representation. Next, a control algorithm associated with the relationship between controller's PWM duty cycle of the MPPT boost converter and solar array output power, namely proposed MPPT algorithm, is introduced. This proposed method is compared with an existing popular MPPT algorithm to confirm its superior performance by using the MATLAB/SIMULINK ® simulation. The results show an improvement in the power generation from a PV array in any weather condition, and also help to reduce the impact of rapid change of solar irradiation on the output power variation within the time duration of change. Therefore, the proposed algorithm reduces the effect on grid frequency and motivate the PV generation penetration into the microgrids. Finally, a 50W DC-DC boost converter prototype is implemented and tested to verify the feasibility of the proposed control scheme.
