DESIGN & FABRICATION OF WIND-SOLAR HYBRID MICROGRID MODELkodibalasriram
This document describes the design and fabrication of a wind-solar hybrid microgrid model. The model combines wind power generation from a small wind turbine and solar power generation from photovoltaic panels to charge a lead-acid battery. It then uses the stored energy to power a motor and LED lighting. The objectives are to generate power from wind and solar sources, store the solar energy in a battery using a suitable charger circuit, and display the electrical power output. Methodology, components, experimental results and specifications are provided for both the wind and solar subsystems as well as the overall hybrid system.
Trends in the geometric size and rated power capacity of offshore wind turbines, the main components of an OWT system, encompassing a typical monopile foundation, the substructure, transition piece, the tower, rotor blades and nacelle (hub). Modern OWTs are installed with either pitch-regulated blades or variable rotational speed systems in order to allow optimisation of the power production over a wide range of prevailing wind speeds. The rotational speed of the main rotor shaft is typically between about 10 and 20 rp. Key electromechanical components of the wind turbine, including the gearbox and the generator (Roberts et al.,2007). The gearbox may cause efficiency losses for the wind turbine and is the particular source of the noise. Recent developments in the design of permanent magnet generators have made it possible to construct some types of wind turbines without the requirement for a gearbox. In this case, the rotor is mainly connected directly to a low-speed multi-pole generator that rotates at the same speed, termed the direct-drive unit. Removing the gearbox mainly removes one of the key components requiring more maintenance, and that is mainly prone to failure. This simplification of the mechanical part allows reductions in size and the mass of the nacelle (Gilling, 2009).

AHI batteries are sealed and contain a safe, water-based electrolyte unlike lead acid batteries which contain corrosive sulfuric acid. AHI batteries provide longer cycle life, require no maintenance, and operate effectively over a wide temperature range. They are well-suited for off-grid and weak-grid solar and energy storage systems where their longer lifetime can significantly reduce the total cost of ownership compared to lead acid batteries.
A Study of the Factors that Affect Lithium Ion Battery DegradationPower System Operation
Due in part to concern over atmospheric carbon and global warming, the move from centralized fossil fuel-based power generation to renewable energy-based distributed generation is growing. Since the availability of renewable energy, e.g., photovoltaic and wind, is independent of electrical demand, battery energy storage systems (BESS) are also under development. Several battery types have been studied for use in BESS, but for a variety of reasons, most new energy storage systems are based on lithium-ion (Li-ion) batteries. Despite their advantages, however, Li-ion batteries degrade relatively rapidly under certain circumstances, which shortens their cycling lifespan, requiring costly replacement. This paper describes the results of a study of the influence of several factors on the degradation of Li-ion battery capacity during repeated charge/discharge cycling, including battery chemistry, ageing, cycling frequency, and temperature.
Haim R. Branisteanu proposes developing a new family of electrical products for renewable energy storage and grid integration. This would include battery storage packs and sophisticated sensors and control systems. The proposal was recommended by scientists at Israel's Ministry of Environment and Economy. Developing these products could save an estimated 800 million ILS per year in Israel by enabling more solar power capacity and reducing reliance on expensive secured gas storage. Branisteanu requests a meeting with Elbit Systems to discuss further developing these products using Elbit's expertise in sensors and control systems.

Design and Implementation of a 30KVA Hybrid Inverter Solar and Utility Supplyijtsrd
The greatest desire of mankind is to have reliable and sustainable electricity. Over the years, conventional, non renewable energy resources e.g. coal, oil, fuelwood etc had been harnessed to generate electricity. However, these resources are depleting with constant usage. This had initiated a switch in attention to renewable energy sources like wind, solar, tidal energy etc. This paper therefore, demonstrates the design and implementation of a 30KVA hybrid inverter using solar panels and utility supply as means of charging so as to generate reliable and sustainable electricity. To achieve this, hybrid inverter with solar battery charging system consists of an inverter powered by a 192V battery was installed. This inverter generates up to 240V AC with the help of driver circuitry and a heavy load transformer. This battery gets charged from two sources, first being the mains power supply itself. If the mains power supply is available, the relay switches to the connection using mains power supply to supply to the load. This power supply also charges the battery for using it as back up the next time there is power outage. The use of solar panel to charge the battery gives an additional advantage of surplus power in case the power outage of mains is prolonging. Thus, this inverter can last for longer duration’s and provide uninterrupted power supply to the user. While the solar panel converts solar energy to electric energy and charge up the batteries during the day with the help of MPPT charge controller, the charge controller was able to accommodate 200VDC from the solar panel and deliver an output voltage 192DCV while converting the excess voltage to current at 192V 100A to the battery. The DC output of the battery was also converted to the usable AC form the inverter. This made it possible for the system output to be used to power domestic appliances. The system design is considered for a residential building in Nigeria. During the test of the solar panels, the results obtained showed that the solar panels were more than sufficient to charge the 3200AH batteries that were connected in series and parallel arrangement for many hours especially during the day. Although, the 192VDC input required by the system to function would not be available at all times in a day, the use of a 192V battery as an auxiliary power source increased the length of time for which the system was available since 3200AH was all that was needed to power the system but another back up of 3200AH was incorporated to span the usage time. The system operate at minimum running cost, pollution free environment, noiseless, reliable and provide the convenient of a twenty four hour power supply. With this system, energy efficiency was achieved.

Charging and Discharging Control of Li Ion Battery for Electric Vehicle Appli...ijtsrd
This paper presents the detailed simulation and analysis of a battery charging and discharging control for electric vehicle EV application using proportional and integral control. A lithium Ion battery model in MATLAB is considered for this study. The purpose of study is to perform a detailed analysis of the charging and discharging operation and observe the behavior of the key parameters of the battery. To realize these two voltages sources have been used, i.e., one is the battery itself and the other is the DC voltage source. The two different voltage source is feeding to a common load. The DC voltage source feeds the load when the battery is in charging mode. When the battery supply is available then it is discharging to feed the load and its control is designed to generate the reference pulses for DC DC converter. The two scenarios have been simulated and results are recorded which shows the effective operation of charging and discharging of a battery source.
