admin — Mon, 19 Dec 2022 11:06:12 +0000

Abstract: This paper presents a study in maximum power point tracking (MPPT) algorithm in solar photovoltaic (PV). With the increase of the popularity of solar PV as power generation method, the effort of extracting maximum power output from the installed PV system remains a challenge. The study aims to identify the performance of the Moth Flame Optimization (MFO) based MPPT algorithm under constant and rapid change irradiance conditions. A simulation model of MFO MPPT algorithm is developed and implemented with a DC/DC Boost converter in MATLAB Simulink. For comparison, a conventional MPPT method, Perturb and Observe (P&O), together with a well-established Particle Swarm Optimization (PSO) method were also included in this study. All the MPPT algorithms were simulated under 10 constant and 10 step changing irradiance test cases. All the MPPT algorithms in study were showing the ability to achieve the maximum power operating point with output efficiency up to 99 %. The performance of MFO is comparable with PSO in term of tracking efficiency and convergence time.

Abstract: EVs are a good substitute to reduce the emissions produced by the transportation industry. Charging stations have been set up as EVs become more and more popular. however, it is impossible to ignore the negative effects that EV charging station loads have on the distribution network’s voltage stability. In this research, an analysis of two voltage stability indicators (VSIs) is provided to forecast the distributions near voltage collapse. These VSIs are based on the idea of the two-bus voltage quadratic equation. Radial distribution systems (RDS) IEEE 15-bus test system was used to assess the behavior of VSIs as base load penetration increased. These indices are differentiated to determine how well they can determine the system’s weakest bus. Results indicate that this evaluation of the indices can be used to position EV chargers in the system.

Abstract: This Paper presents the EV charging coordination approach of the radial distribution system (RDS) for active power loss reduction, stability margin, and voltage profile enhancement. Due to the uncoordinated EV charger load placed in the RDS, some Bus are the strongest voltage stability index where as some of the Bus have the weakest VSI. a methodology to include EV charging systematically at appropriate locations in steps to optimize the loading capacity of the grid with consideration of the voltage stability limits. Since load modelling is a crucial component of an investigation of voltage stability, different EV charger load has been considered. effectively finds the next best position for EV charger in the radial distribution system and with consideration of the stability margin with help of this proposed algorithm. Here, IEEE-15 RDS is considered. This work proposes coordination with two different approaches derived from voltage stability margin. Bottom to Top and Top to Bottom approach algorithms are used for charging coordination of the considered test systems. The principal features of the proposed algorithm are the optimal distribution of the total available power, the EV charger optimal place, reduce power losses, voltage stability, and the priority given to the maximum EV charger’s maximum loading. Therefore, more active power losses are more in the heavily loaded weakest Bus as compared to the heavily loaded strongest Bus. To reduce the active power losses and enhance the voltage profile of the distribution system, coordination is done. The results show that the power loss is reduced and the voltage profile is improved by the coordinated EV charger in the test systems. This work was carried out on MATLAB Simulink 2019b software.

Abstract: With the boom of industrialization and urbanization from the early 20th century, the dependence upon conventional energy sources such as fossil fuels have increased tremendously. Currently, fossil fuels are depleted at an alarming rate and are also causing a hazardous impact on our environment due to the emissions of harmful gases such as carbon monoxide, oxides of Sulphur, oxides of nitrogen, etc. To mitigate such conditions, EVs are introduced where they overtake the traditional IC engines in the field of reducing environmental pollution. Integration of renewable energy sources such as solar, wind energy, hydropower, etc., can play a crucial role when it comes to the sources of charging the EVs. The promising efficiency and abundance of renewables provide an upper hand in the charging of EVs. In this paper, a survey on different charging methods of EV with renewable energy sources has been done. Charging of EV with the integration of renewable sources is advantageous due to its increased benefits.

Nowadays fossil fuels produce highly toxic and colorful exhaust gases which is very harmful to all living beings and also in future the engines which are using these fuels become obsolete due to these aspects. Hence this project is developed for the purpose of using wind energy to power and run a hybrid (electric) vehicle. A windmill generates power from wind energy and this electric power is stored in a battery, meanwhile another battery powers the vehicle alternatively. In the both the ways, the vehicle gets the power from a battery. This project could be stated as there is a compulsory need for an alternative source of fuel to power the vehicle; we can use this system as a beginning for a futuristic alternative for fossil fuels and harness the wind energy in vehicles around the world.
