The mean absolute percentage error (MAPE), integral absolute error (IAE), integral of time multiplied error (ITAE), integral square error (ISE) along with integral time multiplied square error (ITSE) criteria are used for determining the performance indices and minimizing the error. From the investigations of the results obtained in the study, it is inferred that forecasting of electric load based on WT and ANN offers less error as compared to FTS. The suggested integrated model captures the useful properties of artificial neural networks and wavelet transforms in time series and is found to be accurate for real-time data.

In order to overcome these restrictions an improved model of solar module/array has been proposed, this paper presents a step-by-step method for the simulation of SPV panels/arrays in MATLAB/Simulink. The governing curves of SPV array are also investigated for vast range of environmental conditions, substantial parameters and array configurations. The proposed method gives an exact decisive and easy to tune model of SPV array. Moreover, it provides an improved analysis of SPV array for various substantial parameters (series, parallel resistance, diode factor etc.) and environmental conditions (irradiance, temperature and partial shading)aspects.
Review of PV array modelling, configuration and MPPT techniques
International Journal of Modelling and Simulation, 2021

The partial shading causes significant power losses. It is very difficult to maintain uniform irradiance over the entire PV array, especially for rooftop or building-integrated PV systems. The aspects such as connection scheme of PV array, shading pattern and maximum power point tracking (MPPT) techniques, etc., decide the power generated by the PV array. The conventional MPPT methods are only capable of reaching maximum power point (MPP) in identical insolation situations. Hence, conventional MPP tracking becomes inept due to the existence of several peaks in the P-V characteristics. There are different global maximum power point (GMPP) tracking techniques available in the literature that operate in partial shading scenarios. The reconfiguration of the PV array reduces the number of multiple peaks. This reduction in several peaks makes conventional MPP tracking techniques competent even under partial shading conditions with low implementation complexity and higher tracking speed. This paper can assist scientists in choosing a precise objective-based PV module model, connection schemes and MPP tracking methods out of numerous schemes available in the literature.

It is always a challenging task for researchers and industry person to obtain high accuracy of laser beam pointing in presence of various internal and external disturbances. Fast steering mirror, which can jiggle in high and low positions, seems to provide solution to all adverse conditions. This paper presents flexure hinges based modeling and control loop design of Fast steering mirror for precise beam pointing applications. Compensator and Ziegler Nicholas tuned PID controllers are used in control loop configuration. Designed simulation models are tested and compared on number of performance criteria such as bandwidth, gain margin, phase margin, step input command response, which has validated the modeling and design of FSM plant.

Initially, a Fuzzy Logic Controller (FLC) based on prior qualitative information about system dynamics and linguistic performance criteria is developed. Next, proposed Neural-fuzzy model architecture is constructed, which overcome the difficulties and limitations of each isolated methodology. The Neural-fuzzy architecture is developed based on input-output data-sets available from FLC. Fuzzy curve approach is used to determine significant inputs, number of rules, initialization of connecting layers weights, and hence the model structure. Both the controller configurations are tested based on critical performance characteristics such as stability of the loop, responsiveness of the loop and insensitivity to disturbances. Finally, the comparative analysis suggests that the proposed Neural-fuzzy controller completely outperforms the FLC configuration and hence, can be very effective for more precise pointing applications.

The modules receiving higher illumination generate greater power which gets wasted as a heat across modules receiving lower illumination. In this paper we have used MATLAB/SIMULINK software to study the impact of partial shading for basic array configuration (series and parallel connections of modules). The obtained array current-voltage and power-voltage characteristic is verified from experimentally available characteristics. The comparison has been made for series and parallel connected solar photovoltaic modules under partial shading condition and it is inferred that parallel connections must be dominant under partial shading condition. I-V characteristics of Parallel array ...

Therefore, it becomes very important to devise the effective and efficient control strategies for such system to get desired system dynamic performance. In this paper the state space model of the system has been developed, the dynamic behavior of the system has been studied and then optimal controllers are designed using full state feedback control strategy. The optimal controllers are designed for various operating conditions using pole placement technique. The dynamic response plots are obtained for various system states considering various operating conditions. The investigations of these reveal that the implementation of optimal controllers offer not only good dynamic performance, also ensure system dynamic stability.

Day by day the greatest crisis becoming on the earth is Land even though in some countries it is already a biggest crisis. The conventional photo-voltaic system is a land consuming system whereas Solar Tree is based on a tall pole like structure with branches and leaves as panels and it takes only 1% of the land than traditional or classical solar system. Building the solar tree can be very beneficial for the improving efficiency of solar power system. The tests have been performed on the Fibonacci pattern based solar tree and conventional solar panel under the sun light. This technology leads to the development of high efficiency solar panels in the form of solar tree. This work improves the method of collection of sunlight in Fibonacci pattern based Solar Trees.
