Solar photovoltaic-based water pumping system (PVWPS) is emerging as a promising solution for addressing the water needs in rural/remote regions. However, there is a need to increase the utilization of installed PV capacity in such PVWPS as water pumping is required only a few hours a week. To address this issue, in this paper an electric vehicle integrable PVWPS with priority-based control is proposed. It will enable alternative utilization of installed PV capacity and thus would result in improved return on investment. The proposed system is validated through MATLAB simulation. The satisfactory performance of the proposed system has been observed under various operating scenarios. The proposed PVWPS with optimized configuration and design parameters could be further explored in future. © 2023 IEEE.

The world has witnessed a huge increase in the concentration of CO2. Some people believe that it may cause severe disasters. Thus, we develop mathematical models to predict the future trend of CO2 based on its atmospheric circulations. The effects of fossil burnings, plant respiration, oceanic absorption, policy and technology are analyzed and discussed. Results show that the concentration of CO2 will boost in the next 50 years, but the trend will be terminated and inversed if human begin to control the emissions of CO2. © 2023 SPIE.

With the growing prevalence of distributed photovoltaic power plants, various issues arising from photovoltaic adoption are becoming more apparent. This study focuses on stabilizing grid-connected voltage in photovoltaic areas through an examination of a voltage partitioning control method based on the modularity function, which takes into account the compensation device's reactive power compensation capability and the entire network's active network losses. The aim is to quickly regulate voltage to allowable limits while reducing active network losses caused by voltage regulation. When applying the voltage control strategy to the improved IEEE33 node model, the simulation findings demonstrate that this method facilitates optimal usage of each reactive power compensation piece of equipment in the photovoltaic (PV) system while decreasing unneeded equipment losses by minimizing frequent actions among devices. The results approve the viability of the control method proposed. © 2023 IEEE.

This paper proposes a coordinated voltage control by three-phase step voltage regulators (30SVRs) and photovoltaic (PV) units with smart inverters. An optimization problem is formulated to improve the voltage profile of distribution networks and reduce the active power curtailment of PVs. The tap positions of 30SVRs and the active and reactive power output of PVs are coordinated by whale optimization algorithm. The effectiveness of the proposed approach is verified by case studies on the IEEE 123 node test feeder. The results show that the proposed approach achieves lower voltage unbalance while avoiding excessive PV curtailment, improving utility, consumer, and environmental benefits.(c) 2023 The Author(s).

The sliding mode controller is a highly effective nonlinear control design approach that can enhance system performance and robustness. The core concept of this approach is to drive the state variables of the system toward a sliding surface that represents the desired location. This study focuses on designing a sliding mode controller to improve the tracking performance and achieve stability for the desired Euler angles (pitch, yaw, and roll) of a satellite. Nonlinear simulations are conducted to investigate the robustness of the sliding mode control design method under the influence of coupling due to pitch, yaw, and roll rates, as well as time delay through the feedback angles. The convergence of the rate of change of the Lyapunov function to zero is demonstrated to ensure system stability. The simulation results highlight the effectiveness of the sliding mode controller in suppressing the impact of time delay dynamics, in contrast to the classical proportional derivative control design approach, which results in instability. Overall, the study showcases the potential of the sliding mode controller to improve system performance and robustness in nonlinear control systems. © 2023 IEEE.

This paper deals with the Model Reference Adaptive controller (MRAC)-based leader-followers consensus problem of a multi-agent system (MAS) characterized by linearized state-space models. The transmission graph of the agents is undirected among the followers and directed towards the leader agents. Feedback to the leader agent is given from the neighboring agent. The distributed control law is derived based on the relative output errors between the neighboring agents. Closed-loop reference model-based MRAC algorithm is proposed and gives the necessary/sufficient criteria for the existence of the leader-following consensus protocol. The stability analysis of the system with the suggested control framework has been investigated by applying the Lyapunov method. Lastly, a simulation case study is provided to illustrate the proficiency of the theoretical finding. © 2023 IEEE.
