Development of PV array configuration under  different partial shading condition

The main purpose of this paper is to model, simulate, and improve the performance of different 9 × 9 PV array configurations under different Partial Shading Conditions (PSCs) in order to extract the maximum power by defeat the mismatching power losses. Hence, PSCs reduces the performance of Photovoltaic (PV) arrays and increase the Local Maximum Power Points (LMPPs) on output characteristics P-V due to mismatching power losses between the PV panels. For this, Total-CrossTied (TCT) , and proposed Magic Square View (MSV) PV array topologies are considered for the study under Short Narrow shading patterns. PV array configurations enhancements and theirinvestigations are carried out with regard to the comparison of the Global peak of outlet power (GP).The parameters of the PV array configurations are performed in MATLAB/Simulink software.

Wind energy and solar energy are the prime energy sources which are being utilized for renewal energy. The performance of a photovoltaic (PV) array for solar energy is affected by temperature, irradiation, shading, and array configuration. Often, the PV arrays are shadowed, completely or partially, by the passing clouds, neighboring buildings and towers, trees, and utility and telephone poles. Under partially shaded conditions, the PV characteristics are more complex with multiple peaks, hence, it is very important to understand and predict the MPP under PSC in order to extract the maximum possible power. This paper presents the development of PV array simulator for studying the I–V and P–V characteristics of a PV array under a partial shading condition. It can also be used for developing and evaluating new maximum power point tracking techniques, for PV array with partially shaded conditions. It is observed that, for a given number of PV modules, the array configuration significantly affects the maximum available power under partially shaded conditions. This is another aspect to which the developed tool can be applied. The model has been experimentally validated and the usefulness of this research is highlighted with the help of several illustrations

Power-Voltage (P-V) curve and Current-Voltage (I-V) curve determine the performance of the PV system. In this work, the arrangements of the PV module were reconstructed by adding the number of PV module in 3 strings configuration from 5 to 45. This method enhance the performance of the PV system as it able to show the characteristic of the P-V and I-V curve during partial shading and maximum irradiance despite higher number of PV panel. This study focuses on improving the PV array configuration and simulation speed of the PV panel. The simulation of small size PV array is possible, but the problem lies when the number of string and PV module used increases. New PV array configuration is flexible and easy to add string and increase the number of PV module. PV array configuration was modeled using MATLAB/SIMULINK software.

This paper presents an experimental investigation on photovoltaic array (PV array) power output affected by partial shading conditions (PSCs). An experiment setup of a PV array with a series configuration using 2 × 4 photovoltaic modules (PV modules) was built. The power output loss due to the shading effect on the first photovoltaic cells (PV cell) connected with bypass diodes of each photovoltaic module, installed in the PV array in the horizontal direction, was evaluated. Depending on the direction of the sun relative to the PV array configuration, the shading percentage was measured during the test and recorded the current and voltage of the PV array. The performance evaluation of the PV array configurations is referred to with respect to the values of maximum power voltage, the maximum power current, maximum power output, power output losses and fill factor (FF). The experimental results show that 44% shading of the first PV cells affects PV array power output loss by more than 80%.

Simulation Results

Non-uniform conditions on the modules of the PV array, especially, partial shading reduces the output of the PV array to a large extent. The shaded module in a string limits the current of the entire string and hence, the output power of the string. The output power under such conditions is reported to be higher for total-cross-tied (TCT) configuration. This paper describes two different approaches, one based on current compensation (current equalization) and another based on voltage equalization, to extract higher power from the partially shaded total-cross-tied photovoltaic array. The TCT configuration is considered to minimize the number of converters, sensors, cost and complexity involved. The additional converters in the two distinct approaches evaluated here operate only when the partial shading occurs and are controlled to minimize the current and voltage miss-matches. The analysis and the control algorithm are presented. Simulation results obtained in MATLAB/Simulink are included to demonstrate the effectiveness of both methods and the relative merits and demerits of these approaches are highlighted.

This paper discuss about the effect of partial shading on photovoltaic array and driving the dc-dc boost converter to track maximum power point (MPP ) by incremental conductance (INC) MPPT algorithm. The temperature, irradiance, shading and array configuration will greatly affect the Photovoltaic performance. The shading effect on photovoltaic panel are caused by passing clouds ,neighbouring trees, neighbouring buildings ,towers .The PV characteristic of Photovoltaic panel get more complex under partial shading condition. The P-V and I-V characteristic under nonuniform insolation are simulated in Matlab based on solar irradiance and cell temperature. The design and analysis are made simple and easy through Simscape package.
