There is a need to introduce some other means of energy which will long lasting and can produce more energy. Renewable energy resources that are used to produce enormous amount of electricity are solar, hydral, wind and biomass energy. By 2020, the total installed capacity of energy in Pakistan is 34282 MW. Almost 2% of this energy generation is through PV and Wind. But due to current account deficit the import issue related to fuel is increasing day by day. There is a need to develop a cheap and self-sustained model related to energy generation in Pakistan. The population of Pakistan is approximately 230 million and now the culture of residential building is increasing in Pakistan. Due to which the energy demand is increasing rapidly as well. To fulfill those demands, the conventional source of energy is falling short day by day. So, the world is shifting towards the renewable source of energy and building integrated PV system is used for the purpose. Apparently in Pakistan, residential buildings are developing because of the rapid increase in population. So, to accommodate the people residential buildings are the most suitable. But it has the huge energy requirement that needs to fulfilled despite of the energy crisis in Pakistan. Therefore, Building Integrated PV system is used to install PV systems in these buildings to use renewable energy as a source to fulfill their energy requirements. In this research, PV integrated building of 133 KW Power will be analyzed and observed in Lahore. PV modules of 484 units, two invertors of almost 120 KW AC & power ratio of 1.109, batteries of 12 units having voltages of 1234 v and 3853 Ah will be used. In this grid connected building system plane is fixed and tilted at 90/6º, shading is linear and fixed load of 358 KW is observed. The total estimated production we need is to be 3132 MWh /Year. By analyzing the system, it is concluded that the total Produced Energy by the system is 118 MWh/ Year, total used energy is 3131.7 MWh/year. It is also concluded that Perf. Ratio PR is 76.74% and Solar Fraction SF is 3.83 %. Finally, the system is observed for both centralized systems and distributed systems to determine which system gives the most suitable and optimum outputs in different environmental conditions. Different environmental conditions like partial shading or uniform irradiance can be observed and the system can be designed accordingly. With the help of specific algorithms like DFO, P&O, INC and CS the outputs of the system can be deeply observed and the most suitable system can be designed according to the given condition to obtain the optimum outpuItem Module level power electronics in distrubted power system for solar PV application(COMSATS University Islamabad Lahore Campus, 0022) Muhammad Talha Naveed; , SP20-REE-015; Dr. Muhammad Yaqoob Javed; LHR TP 7895hotovoltaic (PV) solar energy is as promising as other renewable energies. Different researchers and engineers are attempting to increase the efficiency of solar PV system. As a result, for PV modules, this enhancement may be accomplished at almost the same level. As is well known, solar PV systems are less efficiency as a result of changing climatic conditions. Module-level power electronics (MLPE) do this by providing the performance improvements of a distributed transmission system in both partial and full shading conditions. As a result, MLPE successfully harvests the distributed maximum power point (DMPP) from solar to accept DC from PV or the grid. Each PV module is connected to the power system via a separate dc/dc converter with Maximum Power Point Tracking (MPPT) capabilities in the DMPP scheme. Each PV panel has a built in power optimization or micro-inverter that helps it work better in partial shade. In order to design the MLPE the efficiency of contemporary string inverters are comparing. The efficiency may be measured in a variety of situations, including uniform irradiation and partial shade. As a result, a DC-DC converter that is attached to each PV module is required to offset shading losses. The optimizer identifies the Local peak using a DC-DC converter from the unit, shuts down the modules during fire situations, troubleshoots, and monitoring a module in a highly efficient manner in this work. On the Matlab software tool, the effectiveness of the proposed power optimizer is displayed. To calculate efficiency, several firms such as SMA, Solar Edge, Huawei, Tigo, and Enphase can use helioscope to compare production and loses data. The results suggest that MLPE produces superior outcomes.Item Enhancing Security and privacy of machine learning based outdoor Air pollution prediction system using IOTA B(COMSATS University Islamabad Lahore Campus, 2020) Muneeba Malik,; SP20-REE-004; Dr. Abbas Javed Assistant Professor; LHR TP 7893Internet of Things (IoT) is a combination of devices, which are network-enabled and work for one shared cause. IoT has transformed several fields and continue to do so, for instance, agriculture, smart housing, development and planning, security systems, and communication networks. The security of IoT networks and devices remains compromised and has not been particularly worked upon. It poses many threats and challenges like jamming networks, insecure physical interface, sleep-deprivation attack and high-level attacks like Sybil attacks, authentication and communication, buffer reservation attacks. To deal with the issue of security, Blockchain Technology have been using advanced security algorithms for hashing and different resources like miners to compute the proof of work. It implements centralized consensus to verify and add more block to the chain acting as an authentication scheme. Over the course of last decade, the decentralized applications and their performance have been under observation while work on them is continuously in progress. Distributed Ledger Technology (DLT) has emerged as an advanced system to record and confirm transactions and authenticate the network to add another node to it. DLT have been used to verify, secure, improve the data that is produced and is sent over any network in its domain. As IoT continues to make progress, it continues to encounter verification challenges. To counter one these issues, a DLT called IOTA Tangle has exclusively been designed for IoT – machine to machine communication. This project aims to work on enhancing security and privacy concerns of machine learning based air pollution prediction system using IOTA Tangle as its resource. IOTA light node and full node will be developed to upload the sensor data securely on Tangle. In this work, performance of the network will be evaluated in terms of end-to-end node delay, power consumption and accuracy of air quality index (AQI).
