Voltage stability issues are most common in severely loaded systems. Today's demand for electricity is enormous, putting the vast interconnected network of power systems under stress. This problem may be solved by boosting generation or lowering transmission losses. The voltage magnitude changes over the permitted voltage stability limit when the load rises unexpectedly. However, for the system to function properly, the voltage magnitude must be kept within the limits. As a result, by providing enough reactive power adjustment, voltage stability may be enhanced. The aim of this paper is to maximize the loading capacity of load buses and simultaneously maintain its voltage stability. STATCOM, a FACTS device is the tool selected for achieving these objectives. This paper explains the analysis carried out to understand the impact of STATCOM on load limit and voltage stability. The required simulations were performed using IEEE 14-Bus Test System. The simulation results are subjected to a power flow continuation procedure, during which critical points for voltage stability and maximum load are determined.
This article explores and analyzes a perturbation and observation (P&O) algorithm in MPPT with three-phase three-level diode-clamped inverters to track the maximum peak power from a solar PV panel. We also describe the concept of three throw power switch for generation of staircase output voltages and control the switching action of power switches by using SPWM for 3Φ 3-level inverter. Through the MATLAB implementation, we get a three-phase, low-harmonic AC output from the DC input of a PV panel.
The use of hybrid storage systems has become a global solution in recent years to supply electronic devices with reliable, continuous and clean energy. Several benefits of energy storage systems can be properly combined through the use of these technologies and an adequate energy supply for specific uses can be achieved. In today's world, there is a constant global requirement for more energy, which has to be cleaner at the same time than energy produced by traditional generating technologies. This has encouraged the penetration of distributed generation technologies and, in particular, renewable energy sources. This paper also discusses various kinds of energy storage devices and studies their demerits and merits of these devices. The observations made from different types of renewable energy sources and their functions in hybrid systems are then analyzed. Certain energy storage systems have been simulated and modelled. In hybrid storage devices, the necessary electronic power circuits have been introduced. Finally, some realistic examples of a hybrid power system such as a battery supercapacitor are modeled, simulated and presented.
Solar cells are semiconductor devices that turn light into electricity. The performance analysis of a Gallium Arsenide (GaAs) based solar cell model was shown using the Analysis Microelectronic and Photonic Structures (AMPS-1D) simulator in this work. A balance of semiconductor compositions, layer thicknesses, and other factors had been studied. The effect of temperature on efficiency has been explored, as the thickness of the top gallium indium layer (GaInP). As the amount of phosphorus in double junction solar cells decreases, the efficiency increases. An efficient and optimised BSF layer is a key layer in both single junction and multi junction solar cells. The use of dual layer BSF for top cells with different thicknesses is explored in this GaInP/GaAs dual junction solar cell study using the Silvaco ATLAS computer numerical simulation TCAD tool. A low-high junction at the back end of a gallium arsenide solar cell has been studied. A back surface field (BSF) is generated by the n+ layer at the rear end of a standard p+n junction solar cell, which improves the open-circuit voltage, short circuit current, fill factor, efficiency, and spectrum response.
Hybrid power systems are one of the most advanced and future-proof power systems in research. Over the past few years, a lot of research has been done on the design, optimization, operation and management of renewable hybrid energy systems. It is clear that this field is still developing and has a large scope for reach. In a hybrid power system, energy generated from non-conventional energy such as wind, solar energy, etc. and energy generated from conventional energy such as a diesel generator are stored in batteries that serve as a power source. In hybrid mode, small wind turbines, photovoltaic systems and diesel generators are connected to the battery. These systems are connected with remote and off-grid locations, which is called a hybrid power system. In terms of cost, efficiency, and dependability, a combination of two or more renewable energy sources is more effective than a single source. This is referred to as a Hybrid Renewable Energy System (HRES) and it is a rapidly growing industry on a global scale. In this review paper, the latest developments in research on modeling hybrid energy resources (wind, PV systems, etc.), backup power systems (fuel cells, batteries, supercapacitors or ultracapacitors, diesel generators, etc.), power conditioning units (MPPT converters, buck / boost converters, battery chargers, etc.), as well as detailed methodologies for managing energy flows are discussed.
