ABSTRACT
The world has now looked towards installing more renewable energy sources type distributed generation (DG), such as solar photovoltaic DG (SPVDG), because of its advantages to the environment and the quality of power supply it produces. However, these sources' optimal placement and size are determined before their accommodation in the power distribution system (PDS). This is to avoid an increase in power loss and deviations in the voltage profile. Furthermore, in this article, solar PV is integrated with battery energy storage systems (BESS) to compensate for the shortcomings of SPVDG as well as the reduction in peak demand. This paper presented a novel coronavirus herd immunity optimizer algorithm for the optimal accommodation of SPVDG with BESS in the PDS. The proposed algorithm is centered on the herd immunity approach to combat the COVID-19 virus. The problem formulation is focused on the optimal accommodation of SPVDG and BESS to reduce the power loss and enhance the voltage profile of the PDS. Moreover, voltage limits, maximum current limits, and BESS charge-discharge constraints are validated during the optimization. Moreover, the hourly variation of SPVDG generation and load profile with seasonal impact is examined in this study. IEEE 33 and 69 bus PDSs are tested for the development of the presented work. The suggested algorithm showed its effectiveness and accuracy compared to different optimization techniques. © 2023 TÜBÍTAK.
ABSTRACT
There are seven types of renewable energy, of which only five will generate electricity. The most extensively utilized renewable energy source for residential usage is solar photovoltaic energy. With over 486GW of generation capacity, solar PV remains as the third largest renewable power source, with advanced photovoltaic (PV) innovation. The United States and China have the most solar plant installations. India holds the third place as the country's solar area is expected to recover completely after the COVID-19 epidemic, wherein the energy from solar PV is expected to overtake coal before 2040. To examine and observe the various processes carried out by solar PV, several experimental studies have been carried out. This research article presents the different case studies of solar PV systems and observes the characteristics of voltage and current or voltage and power for different solar radiations and temperature, respectively. Secondly, the proposed study has observed and analyzed the performance of PV module in series or parallel connections concerning I-V and V-P characteristics. In third section, the shading effects on solar PV module output power is observed. In the fourth and fifth sections, methods to solve the shading module's output power constraint has been studied and finally the MPP is observed by varying the duty cycle of the converter. In the sixth and seventh section, the performance of SEPIC converter is evaluated based on the open and closed-loop systems, and the challenges in buck-boost converter are solved. © 2022 IEEE.
ABSTRACT
This paper provides an effective method for optimal sizing and allocation of DGs & D-STATCOM placement to minimize the actual power losses and improve voltage profile in RDS (Radial Distribution System) with incorporating effect of load growth & load modelling. The technique's legitimacy is tried on the standard IEEE 33-bus RDS by performing load flow analysis after compensating the candidate bus. The outcomes acquired are contrasted with and without the Solar Photovoltaic Panel based DG (PVDG), Wind Turbine based DG (WTDG) and D-STATCOM for minimum actual power loss. Further the changes in the operational circumstances of PVDG and WTDG as well as D-STATCOM, are also investigated in order to fulfil the shifting load profile while preserving the voltage constraint and minimizing real power loss owing to the COVID-19 pandemic. The variation in operational setting and the power supplied to the grid for compensating the coal-based generation during the lockdown, pan-India lights off event and Unlock 1 are also studied in the paper. © 2022 IEEE.
ABSTRACT
The energy transition is accelerating the deployment of new renewable energy capacity. In particular, photovoltaic installed cumulative capacity reached 760.4 GWDC at the end of 2020, with 139.4 GWDC installed in a single year despite the economic shock produced by the COVID19 pandemia. On the contrary, part of the public economic expenditure approved to boost the economic recovery is being invested in building new renewable energy capacity. The different scenarios envisaged by the International Energy Agency indicate a strong increase in the share of solar electricity in future energy production worldwide;in particular, the Net Zero Emissions by 2050 scenario points to reaching almost 5 TW of photovoltaic cumulative capacity in 2030 and surpassing 10 TW in 2040. This colossal growth will require the annual manufacture of millions of solar photovoltaic modules and a diversification of photovoltaic technologies in a market dominated by crystalline silicon technology. Although solar radiation is a inexhaustible renewable energy source, the future demand of raw materials and the energy required to manufacture the photovoltaic cells and the environmental impacts of production and operation of photovoltaic systems demands a detailed sustainability analysis of solar electricity. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
The National Academy of Engineering's “Fourteen Grand Challenges for Engineering in the Twenty-First Century” identifies challenges in science and technology that are both feasible and sustainable in order to help people and the planet prosper. Four of these challenges are: enhance virtual reality, advance personalized learning, provide access to clean water, and make solar energy affordable. In this poster, the authors discuss developing of applications using immersive technologies such as Virtual Reality (VR) and Augmented Reality (AR) and their significance in addressing four of the challenges. Drinking Water AR mobile application helps user easily locate drinking water sources in Auburn University campus, thus providing easy access to clean water. Sun Path mobile application helps user visualize Sun's path at any given time and location. Students studying the Sun Path in various fields often have difficulty visualizing and conceptualizing it, so the application can help. Similarly, the application could possibly assist the users in efficient solar panel placement. Architects often study Sun path to evaluate solar panel placement at a particular location. An effective solar panel placement helps optimize solar energy cost. Solar System Oculus Quest VR application enables users in viewing the solar system. Planets are simulated to mimic their position, scale and rotation relative to the Sun. Using the Oculus Quest controllers, users can teleport within the world view, and can get closer to each planet and the Sun in order to have a better view of the objects and the text associated with the objects. In a camp held virtually, due to Covid-19, K12 students were introduced to the concept and usability of the applications. Likert scales metric was used to assess the efficacy of application usage. The data shows that participants of this camp benefited from an immersive learning experience that allowed for simulation with inclusion of VR and AR. © American Society for Engineering Education, 2021
