Efficient Power Processing Topology For Solar Module Using Power Plane Analysis

Since when it was determined that electricity could be generated from the sun, the power industry has taken slack for not considering it as a viable addition to their generation fleet. However, there are two facts that need to be remembered with respect to the power industry. The first thing to remember is that power has to be supplied to their customers regardless of the weather or the time of day. Secondly, power companies are just like any other company; they are in the business of making money. Because of those two facts, solar energy at its current technological state has no place in the power industry’s current generation fleet.

The PV module has been designed by considering the irradiance, temperature and number of PV cells connected in series and parallel. Figure 5.1 shows the simulink model of solar system. Here only function file used to show the solar system, the program code is given in the appendix. Here we are using a battery. The system is generated 240volt and current is 2.9 A.

Fig. 9(a) shows the DC-link voltage across the DC-link capacitor of the PV array. The DC-link reference voltage corresponds to maximum power point of the PV array. Fig. 9(b) shows the power demand by the load, and power flows from the grid and PV system generated power. As the PV system generated power could not meet complete power demand of load, remainining power is supplied by the grid. At 1secocond the PV system switched from partially shaded condition to uniform solar insolation. Thus, at this point power supplied by the inverter and grid also varies. Fig. 10(a) shows the grid current which is fully sinusoidal. Fig. 10(b) shows the inverter output current. Fig. 11 shows the performance of system under reactive load condition. In this study, a 500VA reactive load is considered. The figure shows the complete reactive power is supplied by the inverter. Thus the power factor of the system is maintained nearly at

Currently solar power is beginning to expand horizontally throughout communities. This growth is creating a demand that is beginning to reduce the expense of purchasing and installing solar panels. The concept is catching on and the technology is improving as the demand increases.

A solar photovoltaic power system is a technology that converts the energy from sunlight into electrical energy. Residential solar photovoltaic systems can offset much of a household's power needs, depending on the size of the system and the household's needs. The output power from is directly proportional to power received from the sun, which varies throughout the day and year. The rated maximum output of the module might be achieved only occasionally, depending on actual site conditions. It is a renewable source of energy that is sustainable and totally inexhaustible. Solar energy is also a non-polluting source of energy that doesn’t emit any greenhouse gases when producing electricity.

Solar Thermal Power systems, also known as Concentrating Solar Power systems, use concentrated solar radiation as a high temperature energy source to produce electricity using thermal route. Since the average operating temperature of stationary non-concentrating collectors is low (max up to 1200C) as compared to the desirable input temperatures of heat engines (above 3000C), the concentrating collectors are used for such applications. These technologies are appropriate for applications where direct solar radiation is high. The mechanism of conversion of solar to electricity is fundamentally similar to the traditional

Renewable energy sources are sometimes used through photovoltaic cells (PVC’s), or solar panels; wind turbines, and water turbines in dams. A PVC takes visible light energy from the sun and converts is to direct current that can be used for electricity (Rouse). This electricity can be used for heat, appliances, and really anything fossil fuel-based electricity can be used for. Connecting PVC’c to each other

Since there is no electrical energy storage in direct-coupled systems, the load only operates during sunlight hours, making these designs suitable for common applications such as ventilation fans, water pumps, and small circulation pumps for solar thermal water heating systems. Matching the impedance of the electrical load to the maximum power output of the PV array is a critical part of designing well-performing direct-coupled system.

As fossil fuels put the planet in peril, hopes for future prosperity in the developing world now rest on bold initiatives of use of renewable source of energy. Solar technology is evolving, costs are coming down and grid connectivity is improving. The dream of universal access to clean energy is becoming more real. This will be the foundation of the new economy of the new century. Solar energy is radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic, solar thermal energy, solar architecture and artificial photosynthesis. Solar panel refers to a panel designed to absorb the sun 's rays as a source of energy for generating electricity or heating. A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.

Current scenario of the globe is that sources for energy are lagging behind the current demand so most concentration is on renewables. Solar performance efficiency mainly depends on cell structure, maximum power point tracking technique and converter circuit used. MPPT operation executes a key part in raising the strength of PV system. A p & o, incremental conductance, Fuzzy based MPPT algorithmic principle is anticipated with a boost converter. Two in and single out Mamdani’s fuzzy framework with triangular membership is used to concoct the controlled current. The anticipated procedure is upheld in MALAB/SIMULINK and in this way the maximum power point tracking performance is evaluated. The anticipated system tracks the most in operation reason with no wavering and enhanced exactness. The reproduction results demonstrate the adequacy of the anticipated method.

While the majority of the world power supply by fossil fuels, such as oil, coal and natural gas, these traditional energy now are facing a number of challenges including the pollutions, rising prices and the limitation of fuel supplies. As a result of these challenges, the alternative renewable power source has been chosen. The reason why solar power becomes a trendy source is that the solar power not only renewable but also has technology development in the future. However, it still has several problems to use this energy generally. This essay will show the limitations of using the solar power system, which including weather dependent, space requirement and the high cost. These drawbacks can be minimized in three ways: Firstly, by using the new innovation which can reduce the effect of weather changing. Secondly, by using the PV system to reduce the space required. Finally, people can apply for the government scheme to release the financial pressures from installing domestic solar systems.

Now a day, photovoltaic (PV) energy system has attracted interest as a next generation energy source capable of solving the couple of problems caused by increasing energy consumption. Photovoltaic system avoids unnecessary fuel expenses, pollution or waste and no vibrations/ noises because the components of power

The purposeof this project is to design a control strategy for a voltage sourced inverter (VSI) that will facilitate the inversion of DC power source, supplied by Photovoltaic (PV) cells, to an AC power source which can be used either to supply load or to connect directly with utility grid. The system will be controlled to obtain maximum active power and maintain unity power factor for the grid-connected solar system.

A photovoltaic (PV) array is a device that converts light into electric power. The power output of a PV array is proportional to the light
