Managed electric vehicle (EV) creates a balance between site energy control objectives and vehicle energy requirements. Fleet cars may always have access to the power they need with regulated charging, easing the burden on the site’s building infrastructure and fostering a more dependable and stronger grid. Charge the executives programming (CMS) is utilized by armada directors, charging administrators, and others to screen and improve electric vehicle charging activities. The CMS needs to integrate easily to existing systems and be robust, scalable, and easy to use. If you want to compare how your electric vehicle charging station works to going into space. The CMS is the name of the mission control center. A CMS can monitor charging activity and control the network’s power usage by connecting directly to EV chargers. To achieve certain goals, it can also adjust the behaviour of the charger within defined bounds. Although the CMS is normally totally automated and doesn’t require human intervention, it has the ability to provide life-threatening alarms. Modern EV charging systems assist in optimizing the operations of charging sites in addition to the basic monitoring functions. The CMS can minimise energy usage during periods when energy is most expensive, for instance, if the charging station utilises time-variable energy costs (TOU rates or demand charges). Here, we’ll go through the fundamental features, advantages, and use cases of CMS to assist you determine whether you should put it into practice. Transactive energy is a system where anyone connected to the grid is able to buy or sell excess energy. In a transactive energy system, traditional consumers employ DERs like solar panels, wind turbines, and combined heat and power systems to generate their own electricity. Nuclear power plants, hydropower plants, biomass farms, natural gas turbines, and trigeneration units are further DER examples. Although utility companies still exist and still deliver power, the

Wheeled mobile robots (WMRs) have exhibited notable competitiveness in various applications, including geo-graphic and planetary exploration. Nonetheless, when traversing on soft terrains, their wheels might encounter sinkage and slippage, leading to mission failure. Consequently, real-time estimation of contact parameters such as sinkage and slip ratio holds significant importance for rover operations. In this paper, we introduce a novel algorithm that employs only one aside-wheel RGB-D camera for the simultaneous detection of wheel sinkage and slip ratio on deformable terrains in real-time. We estimate sinkage through the depth module by processing point cloud data, and we estimate slip ratio through the color module with a sequence of image processing steps. Utilizing only one single camera reduces errors arising from sensor signal alignment and enhances detection accuracy. With a single-wheel testbed, we simulate wheel motion under different slip ratios and carry out numerous experiments to validate the effectiveness of the proposed algorithm. Our algorithm attains a detection frequency of up to 20Hz and exhibits outstanding precision. The relative sinkage error remains below 4%, while the relative slippage error is confined within 0.8%.

The lower limb rehabilitation exoskeleton significantly enhances walking function in patients with lower limb motor dysfunction. Understanding the human-machine interaction force is crucial for studying the control mechanisms of the exoskeleton. This research employs a back propagation neural network (BPNN) to estimate interaction torque, eliminating the need for torque sensors and thereby lowering the cost and complexity of the exoskeleton hardware. Besides, it has higher estimation accuracy compared to the dynamic modeling method. Knowing the torque information, we design a trajectory tracking compliant controller. The controller adopts the admittance control method to ensure compliance and safety. By specifying the desired lower limb motion trajectory, the controller helps guide the user's gait toward the physiology gait pattern. The effectiveness of the controller based on torque estimation was verified on a prototype lower limb exoskeleton. Firstly, the torque estimation error based on BPNN is reduced by 33% compared with the modeling method. Besides, the trajectory tracking controller reduces the absolute value of interaction torque by 30% compared with the transparent mode and makes the user's gait consistent with the target trajectory. This work advances lower limb exoskeleton control technology and positively contributes to the recovery of patients with gait abnormalities.

The space spectral imaging camera is planned to use a Stewart 6-DOF platform to drive a mirror for scanning and imaging, which requires the accuracy of the platform to reach the order of arcsec under the condition of multi-struts dynamic coupling. A Stewart platform realizes high angle resolution mainly by designing high-resolution linear driving struts. The resolution index of the 6-DOF Stewart platform is 2”, which needs the struts to achieve a high resolution of 60 nm. Based on this requirement, a driving strut with 50 nm resolution based on BLDC motor, ball screw, grating ruler is designed, which effectively ensures the high resolution of the platform. The transfer function of the single drive strut is identified by time domain method, and the closed-loop control model of the single drive strut is established. The dynamic performance of the single drive strut is simulated and analyzed. Finally, the dynamic performance of the 6-DOF scanning platform is experimentally studied. The experimental results show that the angular resolution of the 6-DOF Stewart platform is 2”, the swing angle range of the constant speed scanning is −1~1 degree, the nonlinear error of scanning angle in place curve is less than 0.2%, and the rotational speed is adjustable from 40”/s to 1800 ”/s, all the indicators meet the design index. This research has laid a solid foundation for the aerospace application of Stewart Parallel Platform.

Sustainable Energy and Future Electric Transportation (SEFET), international conference on

作者： Rohit Kumar Bhim Singh Electrical Engineering Department Indian Institute of Technology Delhi India

The influence of the power converters {multi pulse and multilevel} on the medium voltage drive, operating in steady state and dynamic conditions, is discussed in this paper. As a hybrid, multilevel inverters have been proved an important alternative to the conventional inverter in the medium voltage motor drive. Hence, to address the power quality challenge at the drive end of the medium-voltage drive, this paper exhibits a seven-level hybrid multilevel inverter for driving a medium-voltage drive. Here, the seven-level hybrid multilevel configuration is developed through the cascaded arrangement among the bridge configured NPC with the H-bridge. Furthermore, to address the power quality challenge at the grid end of the medium-voltage drive, fifty-four pulse AC-DC power converter is designed and developed, which also works as a power transforming converter among the DC-link's of exhibited hybrid multi-level inverter and grid supply. Here, the lower-order lower-order harmonics are effectively suppressed from the input source current waveform by the employing phase displacement technique on the multi-winding transformers. First, a thorough analysis of the power converter's design and operation is carried out for the medium voltage drive system. Second, the bio-inspired genetic algorithm is utilized to find out the optimized solution of the selective order harmonic trigonometric equation, which further helps in the effective suppression of the lower-order (5 th and 7 th ) harmonics present in the output voltage waveform of the hybrid multilevel inverter. Moreover, a field-oriented control-based realistic drive is implemented with a much-simplified simulation.
