    Combined scheduling of electric vehicles and renewable energy under uncertainty
    (University of Management and Technology, 2017) Bilal Ahmed
    The increasing energy demand due to industrial and consumer load as well as population has made it imperative to seek out various other resources to harness power. Conventional methods of electric power generation have failed to keep up with the demand in the energy; it is a rather depleting source of power production. These hydrocarbon fuels also pose a serious threat to the environment as the global warming has increased significantly due to their use. The need of the hour is to develop such a system which would be able to cater the needs of the increased energy demand as well as be less of a threat to the environment. Much research has been done on the renewable energy resources and it has produced significant results. With the advancement in research and development, more efficient and better means of electric power production have been devised. The instances include the ever-improving PV panels, Wind energy units and Energy produced from biomass etc. The concept of micro-grid is exactly the crux of the above discussion where conventional power producing resources work in parallel with the renewable energy resources in order to provide smooth and uninterrupted power supply. Clever algorithms and methods have been devised so that all resources work in synchronism with each other in an optimal way.The aim is to amalgamate the resources in such a way that we are able to get the maximum output power at a minimum cost. Various cost effective optimization schemes have been employed in order to yield a balanced system with a low operating cost and a very good efficiency. Incorporation of the optimization methods into the system not only renders it cost effective and efficient, it can also produce profit to consumer when the designed system supplies power to the grid. The demand of electrical vehicles has risen significantly in the recent years. These vehicles offer zero emissions resulting in no harm to the environment. Vehicle to grid (V2G) is technique that has evolved over the years in the developed countries where a fleet of electrical vehicles can provide surplus power back into the grid hence profiting the consumer. Later in this dissertation, this V2G strategy has been extensively addressed. The aim of this dissertation is to provide a combined Electric vehicle and renewable energy resources schedule using the technique of stochastic programming.

    Short range communication using visible light
    (University of Management and Technolog, 2017) Mian Zeeshan Akbar; Zubair Ali Khan; Muhammad Saleem
    Goals of this project are to study and optimize short range communication using visible light for increased data rates and less noise. Using light instead of conventional means of communication can help in reduce problems relating healthcare. Using LED instead of SONAR can help reduce threat to marine life, while increasing data transfer rate and minimizing noise caused by water for conventional communication instruments. This thesis will give information and follow through of a system which will allow electromagnetic radio signal to be converted into modulated light signal with frequency shifting modulation and transmitting it with the help of crystal LED. Modulated optical signal can then be transmitted into a photo diode to demodulate received signal back into electromagnetic signal. It can replace all conventional means of communication in future if more LEDs of high intensity are manufactured.

    Harmonic analysis of grid connected photo voltaic system
    (2017) Omar Raza Khan; Awais Rehmani
    Since nonrenewable energy sources are depleting extremely fast. Pakistan is in grave danger in the next couple of decades, so if we don’t take our mind towards renewable energy sources like sun, then there may not be any electricity in Pakistan to lamp our houses. The aim of this project is to provide a solution for the energy crisis that is not only cost effective, but also easy to implement. The project focuses on maximizing the solar power generation through batter inverter control and working. This project provides a way to keep grid electricity usage to minimum and utilize the solar energy as much as possible, and in case of extreme conditions of weather a battery plan is also available. As well as smart grid photo voltaic system connected to the power grid in this case there is need to minimize the harmonic distortion to standard level which depends on different technique of inverter control.
