What Is The Impact Of Renewable Energy, And What Is It Has Increase In Distribution Network?

installing solar panels are changing tastes and preferences of consumer. As Energy Sage (n.d.) stated,

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

Photovoltaic (PV) is the most common solar collector used today; an example is the panels people put on rooftops or vending machines.

The switch to clean energy in the United States and around the world is a difficult necessity that must be met within the subsequent five to six decades. The prolonged use of damaging fossil fuels and other unsustainable forms of energy are greatly damaging the planet. These sources of non-renewable energy are bound to run out in the following century. Millions of square kilometers of Arctic ice has melted so far, the sea level is rising, and the CO2 levels present in the atmosphere are drastically increasing (Chang). The transition to renewable energy must be met; however, this is not a process possible to achieve overnight. This change will require an extensive amount of resources and time but will reap many benefits to the users of this growing technology.

5.8. Short-circuiting the PV panels: (a) grid voltages & grid currents; and (b) dc-link voltage when applying a 60% SLG voltage sag at MV side of the transformer.

The amount of electrical energy generated from the PV array exceeds the demand in the building. This helps offset the energy demand for the building while winter months as much energy is used in heating the rooms. To ensure low energy consumption levels, various innovative power-saving measures have been adopted. For instance, all office electrical panels go off automatically at night. Additionally, ecological plug systems have been incorporated in the laboratory to aid the laboratory users to disconnect nonessential equipment.

On the other hand, Canadian solar has been experiences losses in the past three years causing cash flows problems and increasing allowance for doubtful accounts due to the economic crisis. Also the company's customers often buy on credit terms thus at any point of time can declare bankrupt or take a very long time to repay their debts making Canadian solar short on cash. Other risks include a sudden end in demand, sales price declining, dislocating business model assumption, capital ties and currency fluctuations.

First of all, solar power is not a reliable nor predictable energy source. The amount of electrical energy generated by solar panels in a large area depend on the weather. For example, during a cloudy day, the whole Lafayette area would be cloudy, which means all solar panels in the entire area won’t work. If solar energy is a significant source for the area, the power company has to dispatch energy from other areas to fill the deficit caused by the unavailability of solar panels. Usually dispatching involves more than one area, since people must collect enough excess power to compensate the deficit. This is called the propagation of disturbance in a power grid, which means, a fault or dispatch action in one area will quickly spread to the entire system, causing many unexpected behaviors and make the controls much more complex. Every minute the weather in the whole country is changing, causing some areas receive more solar energy than average, some receive less. Since the entire US power gird is connected (it also expands to most parts of Canada) and every “small power production facility”, which PURPA encourages, is a source of disturbance and spam the entire grid in a short time, the grid would be messy and unpredictable. The power grid is the largest and most complex nonlinear system that human ever built, it is already very hard to model and control, adding more disturbance from solar panels will only make it even harder to control. In fact, people already can’t analyze the behavior of the power grid, the actual behavior of most components in the system is always different from model

Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is

For all these system types, investing in a PV system also means locking in the long-term pricing of your electricity. With a photovoltaic system, you are buying 40 to 50 years of electricity at a fixed price, while maintaining the benefits of being on grid.

•Electricity distribution businesses on regulatory issues associated with connection of distributed generation and tariff structures, including Electricity Authority investigations.

Solar panel distributors serve as a middleman in the industry to ensure that deals are facilitated properly. Logistics for such products can be very complex, and the company must have a great deal of strategic assets capable of delivering to many global locations.

SAM has three different choices for the user to choose from to modeling a photovoltaic system; The PVWatts System model which is an implementation of NREL 's online photovoltaic calculator, the Flat Plate PV model which combines and separates module’s component models that are available for the user to select and; and the High-X Concentrating PV model which is for concentrating PV systems. All three
