This research estimates the power loss in photovoltaic (PV) systems through a Random Forest model by using 15-min interval data for two years (2021–2023) of operation from a university campus located in Delhi, India. Irradiance, temperature and the dust concentration were used in the analysis to calculate and estimate actual and theoretical potentials and power losses based on factual, modelled and theoretical determinations under Standard test conditions (STC). Seasonal changes are of particular interest and therefore, the power loss is to be analyzed based on three power quality reports obtained over three different seasons in 2023. The results of the model show the Mean absolute error (MAE) to be 29.145 W along with Root mean square error (RMSE) to be 57.72 W. Interactions with power loss observed seasonally proved to have variations in dust and power loss, temperature, and so on; all of which confirmed the effectiveness of Random Forest model in providing valuable predictions of season-sensitive data. These results would be significant to enhance the efficiency of the PV system and how energy technologies for dusty areas should be designed.

For grid-connected photovoltaic (PV) systems, accurate solar irradiance forecasting is crucial, especially in cases of intermittent environmental conditions, in order to ensure grid operation, scheduling, and grid energy management. Solar irradiance, temperature, and other meteorological factors significantly influence PV generation and also make it intermittent in nature. Time series analysis provides an efficient way to map temporal patterns, like hourly, monthly, yearly, and seasonal variations, and within solar irradiance data. In this paper, time series forecasting of 24hourly future observations of global horizontal irradiance (GHI) is done using a multilayer perceptron (MLP) of deep learning framework. Different hyperparameters like hidden layers, hidden units of each layer, activation function, optimizer, and lag observations/steps are tuned to develop the best model that fits the GHI historical data. Further dropout regularization is used to avoid overfitting the model. The model is validated using validation data that the model has never seen before. RMSE, MSE, MAE, and NRMSE errors, aiming at minimizing forecasting errors on test data, are used to select the optimal value of hyperparameters. © 2023 IEEE.

Partial shading imposes a major issue while generating power using solar photovoltaics (SPV) and consequences in the formation of hot spots and manifold peaks in the power-voltage (P-V) curve of the SPV arrays. As a result, a main deforming concern arises i.e., The power loss due to mismatch in the SPV system is dependent on and directly caused by the shading pattern. Mitigation of this MPL can be assessed by selecting a proper configuration of the SPV array and optimal shading dispersion over the complete SPV array. This paper focuses on the implementation of renowned metaheuristic algorithms (MAs) to optimally disperse the shading effect for a partially shaded total-cross-tied (TCT) SPV array configuration. A partial shading effect is generated using a realistic moving cloud model by incorporating various affecting environmental parameters. Furthermore, MAs are tested for the designed moving cloud model and a comprehensive analysis is presented among the various SPV array configurations. © 2023 IEEE.

Transfemoral amputation commonly occurs due to some stroke, diabetes, physical or mental trauma, which reduces the person's movement capability. Therefore, an efficient prosthetic leg is essential to improve the life of an amputee by replacing the lost limb. This letter addresses the fuzzy logic-based control strategy for magneto-rheological damper based prosthetic leg for transfemoral amputees. The primary focus of this letter is to present the performance analysis of the control to achieve the entire gait cycle (both swing and stance phases) for a transfemoral prosthesis. The performance and robustness analysis of the developed prosthetic leg is tested for real-time gait data to obtain the precise and more natural gait by the transfemoral amputee. © 2020 IEEE.

Due to lack of electricity, many communities in India employ fossil fuel-based water pumping systems for irrigation. Due to the dangerous greenhouse gases they release, fossil fuels seriously impact the ecosystem. In this study, a solar energy-based automated water pumping system is suggested that can be deployed in many villages. The automatic system only activates the water pumps when the soil moisture content falls below a specific level, as measured by the moisture sensors positioned across the fields. This paper describes the advanced development on controlling and operating solar water pumps using the internet and messaging control for turning ON and OFF. The main aim of this type of system is to make it user-friendly, reliable, easy to handle and more efficient so that people can use it easily without facing any difficulty. This system saves electricity, produces a pollution- free environment, and also reduces the running cost. In this research work, modelling of an MPPT based solar water pump system is done in proteus software, which focuses on controlling the MPPT output power and switching of the solar pump. The Hill Climbing (HC) algorithm based MPPT is designed, which is coupled with a boost converter for obtaining high solar energy output. The overall output of the system is controlled by the Arduino programming based controller for automatic switching of solar pump. © 2023 IEEE.

Electrical energy is produced by exploiting the kinetic energy from the wind. However, higher wind speeds above the rated speed may harm the system, so there is a high need for effectively maintaining its operation beyond the rated speed. Therefore, in this paper, leveling of power output is carried out by regulating the blade pitch angle of a doubly fed Induction Generator (DFIG)-based wind turbine. The control mechanism of pitch angle is used to regulate the power output and to smoothen power fluctuations whenever the wind speed becomes greater than the rated speed. The fuzzy logic-based control scheme is utilized for controlling the angle of a pitch to sustain the rated power at the output. Simulation results and studies show that this control mechanism is very potent in reducing fluctuations and leveling of the output power of DFIG-based WECS (Wind energy conversion system) as compared to the PI control strategy. This given technique is verified by MATLAB/SIMULINK software, the results are obtained on various operating conditions, and finally, comparisons are drawn with the PI and fuzzy controller. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The world's non-renewable energy sources are finite, and Chandigarh is not an exception. Its energy sources for producing electricity are limited. It also lacks a power plant of its own. Finding alternate sources of electricity supply is vital since the population is growing and so is the need for electricity. As demonstrated in this study, Chandigarh's population growth will increase the city's demand for electricity. Even if the government of Chandigarh increases the capacity of the electricity supply, obtaining the necessary supply will be expensive, the plan is not sustainable. Therefore, Chandigarh is integrating renewable energy sources for its electrical supply in accordance with the global trend towards greater use of renewable energy sources. In addition to projecting Chandigarh's population and electricity consumption for 15 years, until the year 2035, this study also looks at viable alternatives to electricity production in the city. © 2024 IEEE.

This paper attempts to control the plasma level of glucose for a diabetic patient. A mathematical model of glucose and insulin interactions in the patient's body proposed by Bergman is used in this work. A two-degree of freedom PID control scheme is designed to control the insulin injection in the body for the efficient regulation of plasma glucose level. The controller parameters are optimized using different evolutionary algorithms i.e., ACO, PSO and GA. A conventional PID controller is also used to control plasma glucose level and the response is studied for 24 hours. A disturbance term representing the glucose infused due to meal intake is also included to analyze the control performance during disturbances. It is revealed from the results that GA tuned 2 DOF PID controller provides the best performance among other designed controllers. © 2022 IEEE.

The purpose of this research is to employ non-integer order calculus to enhance the control action of the non-linear fractional order fuzzy PD plus I (FOFPD + I) controller. To operate a non-linear 6-DOF Puma 560 robotic arm, a FOFPD + I controller is developed and implemented. Fractional order fuzzy proportional derivative (FOFPD) and fractional order fuzzy integral (FOFI) controllers are used to create the proposed controller. Because of the non-linear gains, the proposed control approach preserves the linear structure of the fractional order proportional derivative plus integral (FOPD + I) controller while still providing adaptive capabilities. Further, the PID controller is also derived to compare with the FOFPD + I controller. Both, FOFPD + I and PID controller’s parameters are optimized using non-dominated sorting genetic algorithm-II (NSGA-II). The performance and effectiveness of the presented controller are examined in terms of trajectory tracking, tracking error, and robotic arm control efforts. Simulation shows excellent performance of FOFPD + I controller over traditional PID and fuzzy logic controllers. To be precise, on the current optimal solution, suggested controlling strategy is more than 80% efficient than other strategies. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
