“…The single switch topology can considerably simplify the circuit compared with conventional equalizers requiring multiple switches in proportion to the number to PV modules/substrings. The various maximum power point tracking algorithm was studied from the papers [3]- [7]. Due to climatic condition the maximum power extracted from the PV cell is varied.…”

“…Therefore Maximum power point tracking algorithm is essential to track global MPP from each panel. Due to the variation of the maximum power point (MPP) of photovoltaic (PV) generators with solar radiation and temperature, boost dc-dc converters placed between PV modules and inverters in grid-connected PV systems have to be controlled in a variable operating-point condition [3], [5]. I is the photovoltaic cell current, V is the PV cell voltage, T is the temperature (in Kelvin), n is the diode ideality factor.…”

The power-voltage (P-V) characteristic of a photovoltaic (PV) array is nonlinear and time varying with the change in atmospheric conditions. As a result, the maximum power point tracking (MPPT) technique must be applied in PV systems to maximize the generated energy. The incremental conductance (INC) algorithm, one of the MPPT strategies, is widely used for its high tracking accuracy, good adaptability to rapidly changing atmospheric conditions, and easy implementation. This paper presents a modified asymmetrical variable step size INC MPPT method that is based on the asymmetrical feature of the P-V curve. Compared with conventional fixed or variable step size method, the proposed method can effectively improve tracking accuracy and speed. The theoretical foundation and design principle of the proposed approach are validated by the simulation and experimental results.

“…There have been many algorithms developed for MPPT [3], e.g. perturbation and observation (P&O) method [4], the fractional open circuit voltage or short circuit current [5,6], the fuzzy logic control [7]. Basically, these methods is considered and evaluated under a fixed environmental condition including irradiance and temperature by the name of static MPPT performance.…”

Photovoltaic (PV) system has been regarded as one of the most popular renewable energy sources due to its easy installation and safe operation. As one of the key control algorithms, maximum power point tracking (MPPT) function of PV inverter has been researched widely. Usually, its performance has been evaluated under a fixed environmental condition including irradiance and temperature. However, recently the dynamic MPPT performance under varying irradiance conditions has been paid attention to the PV society. As the European standard EN 50530, which defines the recommended varying irradiance profiles, was released lately, the corresponding researches have been required to improve the dynamic MPPT performance. This paper presents the design and evaluation of the improved dynamic MPPT performance using the modified P&O MPPT method under EN 50530. By using 250 kW PV inverter, the performance of the modified P&O method is evaluated and compared with the conventional P&O MPPT methods. The experimental results show that modified P&O method shows higher dynamic MPPT efficiency under EN 50530than the conventional P&O one.
