“…MPPT TECHNIQUES Owing to the nonlinear characteristics of PV cell the maximum power of a PV system varies with ambient conditions, and there is a unique value of array current and array voltage, product of which defines the maximum power point of a PV module. Hence for efficient operation of the system, the PV module must operate at MPP in all ambient conditions [10].…”

In this paper a photovoltaic powered Z-source inverter system with a R-L load is considered. The photovoltaic cell model is developed in MATLAB and it is considered at different irradiation levels and temperature. The mathematical model of cell used for simulation study is single diode model. Maximum power point tracking is implemented using perturb and observe method. This paper focuses on applicability of double carrier PWM technique and analyzes the comparison between the performance of simple boost control and double carrier control. Simulations and analysis are performed to advocate the double carrier control scheme.

Under partially shaded conditions (PSC), a photovoltaic (PV) array takes on more complex characteristics. It is very difficult and utterly necessary for PV system designers to understand and predict them. Other than the prevailing methodology of solving a set of non-linear equations, the proposed methodology focuses on three key points of short circuit, MPP and open circuit. Besides, its V-I curve is split into three regions and replaced by three asymptote lines. From this viewpoint, this paper presents a novel Psim-based piece-wise linear macro-model whose circuit parameter values are determined based on the foregoing three key points. The novel model, compared with the other published models, is characterised by short running time, relative high accuracy, and reliable unique solution. This model avoids the computational complexity and convergence issue. Furthermore, based on the novel model, an optimising configuration-simulation model is presented for PV system designers to optimise PV array configurations under several given shaded patterns. Two new concepts of power and voltage reducing rate shall be introduced to estimate the PSC effect. The novel model and formulas, therefore, shall provide a good solution for studying the behavior of a large-scale PV array in a complex scenario.

Optimum utilization of photovoltaic (PV) energy is possible if PV system is operated at its maximum power point (MPP).Since the MPP varies with change in irradiation and temperature, appropriate algorithm must be incorporated in the PV system to track the MPP. There are number of maximum power point tracking (MPPT) algorithms available in the literature with its own merits and demerits. Among different MPPT methods, perturb and observe (P&O) method is most popularly used for its easy implementation and simple structure. But conventional P&O method is sluggish in nature due to its fixed perturb amplitude. To overcome this, an adaptive P&O algorithm is proposed here based on current perturbation which has faster dynamics compared to the conventional P&O method. The effectiveness of the proposed method is verified using MALAB/Simulink both in steady as well as changing irradiation. Keywords-Photovoltaic(PV) Modeling; Maximum power point tracking (MPPT); Perturb and Observe (P&O);Adaptive P&O.
