The design of a virtual electrical lab offers a myriad of advantages that contribute to a rich and effective learning experience. One key strength lies in its accessibility¿students can access the virtual lab from anywhere, breaking down geographical barriers and allowing for flexible learning schedules. This democratization of education ensures that individuals, regardless of their location, can engage with practical electrical experiments. Moreover, the virtual electrical lab provides a safe environment for experimentation. Unlike traditional labs, there's no risk of electrical accidents or damage to equipment. This promotes a stress-free learning atmosphere, encouraging students to explore and experiment without fear of negative consequences. This safety aspect is particularly crucial in nurturing a student's confidence in handling electrical concepts and applications. Interactivity is another standout feature. The virtual lab can simulate a wide range of scenarios, allowing students to experiment with different parameters and observe outcomes in real-time. This hands-on approach enhances understanding and retention, as students actively participate in the learning process.

Smart grid is the conception of use of digital information. It controls technology to improve reliability, security, and efficiency of the existing electric grid with dynamic optimization of grid operations and resources, with full cyber-security. Smart grid deployment and integration of distributed resources and generation includes renewable resources for development and incorporation of demand response, demand-side resources, and energy-efficiency resources. So, presently Smart Grid Technology became a hot issues. This book is based on the research of Smart Grid Technology with Smart devices and Smart applications for Smart Cities for digital India.

This book describes the solar power and piezoelectric based energy optimization and appliances control. The increase in energy consumption of portable electronic devices and the concept of harvesting renewable energy in human surrounding arouses a renewed interest. This book focuses on one of such advanced methods of energy harvesting using solar cell and piezoelectric material. Piezoelectric materials can be used as mechanisms to transfer mechanical energy, usually ambient vibration, into electrical energy that can be stored and used to power other devices. A solar tracker is used in various systems for the improvement of harnessing of solar radiation. The problem posed is the implementation of a system which is capable of enhancing production of power by 30-40%. The control circuit is implemented by the microcontroller. The control circuit then positions the motor that is used to orient the solar panel optimally.
