Electricity is the elementary need for the economic growth of any country. Transmission and Distribution (T&D) system plays a crucial role in transferring power from utility to consumer end thus proficient design can lead towards reduced demand and supply gap. Pakistan is facing energy crisis for more than a decade, so efficient T&D system can help in minimizing the shortfall of electricity. This paper offers ways to gratify the combination of Economic Load Dispatch (ELD) with the perspective of planning distribution network while considering Radial Distribution System (RDS) and Mesh Distribution System (MDS). Genetic Algorithm (GA) optimization is implemented for ELD taking in account generation units, generating at different fuel cost for the IEEE 69 base case. Furthermore, a cost to benefit analysis is carried out while discussing different case studies, upgrading distribution network and decrease per kWh cost by considering different techniques.

In the following paper, the parameters of the Proportional-Integral (PI) controller of the DC-DC boost converter are tuned with and without using the accelerated particle swarm optimization algorithm (APSO) and the performance of the converter is analyzed under the effect of the variable irradiation level of the photovoltaic (PV) module. The mathematical modeling of the photovoltaic module is implemented in the MATLAB/Simulink having two variable parameters, temperature and irradiation level to change the output of the module. The output of the PV module is fed to DC-DC boost converter having a particular value of the duty cycle ratio to increase the voltage to the desired constant value. A three phase sinusoidal pulse width modulation (SPWM) inverter having DC link voltage coming from the converter’s output is simulated in the MATLAB/Simulink and a three phase resistive load is connected across the output terminals of the inverter to get phase and line voltages of the inverter. The irradiation level is used as a variable parameter having a step change at regular intervals and the output voltage of the DC converter under the close feedback system is observed. A comparison is made between the tuning parameters of the PI controller calculated with and without using the Accelerated particle swarm optimization algorithm.

Tri-wheeler automobile mostly called as “autorickshaw” is commonly used in South Asia as the cheapest source of transportation. These tyres of vehicles usually use two- stroke or four-stroke internal combustion (IC) engine. The main flaw of this automobile is its colossal emission of severe gasses like CO2, which is the main element for air pollution. On the other hand, gasoline, used by the IC engine as an energy source, will be diminished ultimately. So, to avert this environmental change, we should abstain the use of gasoline. This paper presents electrification of tri-wheeler in which lead-acid batteries are used as an energy source. Brushed less direct current (BLDC) motor and complementary controller are used to transfer the electrical energy into mechanical energy. Calculation for component sizing shows 3kW BLDC motor is required for the traction of vehicle with desired load at desired speed and 125 Ah battery bank is required. Tests are conducted using 2-Stroke auto-rickshaw body and chassis. Road testing of vehicle was conducted and data was logged. Obtained results from the logged data shows that electric vehicle is feasible for transportation and results are acceptable. The main focus is on the calculation of propulsion power, component sizing, and resultant drive cycle analysis. Results show that the energy used by the battery is much cheaper than gasoline with zero carbon emission.

Savonius type vertical axis wind turbine (VAWT) has a tremendous potential for small scale power generation. Performance of Savonius type VAWT is mainly affected by different operating conditions. Hot climate condition has been considered an important meteorological factor which significantly effect on the performance of turbine. In this study, numerical simulations using CFD FLUENT are perform to investigate the flow characteristics and evaluate the performance of Savonius type VAWT at various hot inflow air temperature. CFD analysis has been performed at different tip speed ratio and different angle of rotation of rotor blades. The results show that the maximum power coefficient and torque coefficient 27.5% and 48.5% are obtained at tip speed ratio (TSR) 0.9 and 0.6 respectively. It is also concluded that performance of Savonius type VAWT decreases as the hot inflow air temperature increases. Maximum and minimum power coefficient is achieved at 15°C and 45°C respectively. It is investigated from the previous study that hot climate conditions has an important climate factor which will be a necessary consideration during the design and optimization of Savonius type VAWT in future.

The synthesis of anti-soiling, hydrophilic, antifogging, anti-reflective and low refractive index Nano-particles of silica was carried out using Stober’s process. The silica Nano particles were synthesized under increased angular velocity on the magnetic stirrer while the stirring time was decreased accordingly. The reaction was carried out under ambient conditions. The glass substrate was coated via dip coating technique. The hydrophilic nature of the surface was due to the Si-OH bonds formed after the hydrolysis and partial condensation of the sol has been carried out and the particle size obtained was in the range of 10-14 nm. The porosity of the surface was increased due to the pores of Nano-particles which aided in decreasing the refractive index of the surface to 1.29, hence increasing the transmittance of the surface by 5-6 %. The maximum transmittance of 99% was obtained at the wavelength of 600 nm. The durability of the surface was further increased by calcining the coated substrate glass at 500° which made the hydrogen bonds much stronger than they were before and increased the surface hardness. The synthesized coating has wide range of applications in PV-Modules due to its self-cleaning, anti-soiling and super hydrophilic nature.

Renewable and green energy sources are need of the hour and are gaining much consideration then other conventional sources for generation of electrical energy. Amongst these renewables, electricity generation through solar energy plays a pivotal role. Different techniques including Concentrated Solar thermal collectors and Photovoltaic cells are being used for generation of electricity from solar energy. The efficiency of these systems depends purely upon the amount of received solar radiations. To increase efficiency, these solar surfaces can be made to track the sun during the whole solar day maximizing the collection of solar irradiance. This paper presents the simulation of solar tracking angles for maximizing the efficiency of solar thermal collectors. Astronomical algorithm is used for calculating solar angles and the simulated results are thereby presented for the surface tracking angles. Furthermore, Irradiance data collected form Meteorological Station for a whole year is analyzed indicating solar potential for Lahore area.

Voltage stability and reliability is the major concern in radial distribution system (RDS). Customer far away from the substation faces voltage reliability and system fluctuation issues. These issues should be resolved through different methodologies under smart grid paradigm. Studies proved that loop and mesh distribution systems (MDS) show better voltage reliability and stability than RDS. A comparative study of different load models is done in terms of losses, voltage profile and cost of active power losses in both radial and mesh distribution system. Two different multiple-criteria decision analysis (MCDA) techniques PROMETHEE and Weighted product model (WPM) are used to identifying the best decision by considering active power loss, voltage and cost of active power cost attributes. A distinctive voltage stability index (VSI) is used to find the critical bus which is highly sensitive to voltage collapse. The bus having lowest VSI value is the most critical bus which is optimal location for siting the distributed generation unit (DG). VSI is evaluated for both radial and mesh distribution network. Different load models; constant power (CP) and constant impedance (CZ) models are used in this paper. The impacts of CZ and CP load models have been observed on voltage profiles and system losses on IEEE 33 bus system.

Pakistan is having an energy crisis since long. It is very hard to fulfill the present energy demand with available energy resources. In this paper, we are designing simulation-based hybrid systems using Photovoltaic, Wind, and biomass and comparing them for the best optimum result on the basis of net present cost NPC, Levelized cost of energy COE and energy payback period. The load demand of the locals is calculated through the survey. Hybrid optimization model for electric renewables HOMER Pro is used for the optimization of hybrid systems. Four strategies are employed based on the availability of resources. In the first strategy, we use solar and biomass as an energy resource to feed the community. From optimization results it is found the most expensive system with total NPC of Rs 18.4 M, Levelized COE to be Rs 18.09, and the payback period of 2.79 years. In the second strategy, we are using wind and biomass resources. Here, NPC and Levelized COE reduce to Rs 17.8 M and Rs 17.53 respectively with the payback period of 2.28 years. In the third strategy, we are employing solar and wind resources. In this, HOMER lower down NPC and Levelized COE to Rs 14.5 M and Rs 14.87 respectively but increases the payback period to 9.10 years. In the last strategy, we are using all available resources PV, wind, and biomass. Here, Levelized COE reduces to Rs 14.40 while a minor increase occurs in the NPC from the third strategy i.e. Rs 14.6 M with the payback period of just 2.54 years. Based on the NPC, COE and the payback period, HOMER executes the optimization for all strategies and found the first strategy to be the least feasible and last strategy the most feasible.
