Free Report About Renewable Energy Integration

A National Grid is a very high voltage network of electric power transmission that is connecting various power stations and substations within a country. It is the central place where all the power produced from different parts of the country are connected and then distributed evenly to the consumers according to demand. These national grids help in maintaining an instant balance between demand and the supply at the same time moving electricity to the consumers from the generation source (Lund, 2005). The amount of electricity fed into the system must balance the load to keep the system running and operational since it always very hard to store electricity.
The world today is moving towards the renewable sources of energy and electricity. The non-renewable energy like coal and petroleum have been found to be very expensive and unsafe to the users. These renewable energy including solar PV, wind, hydro, and biomass electricity have become the main sources of energy in different parts of the world led by the United States of America (Li & Wolfs, 2008). The high demand f electricity in domestic and industrial set up have also facilitated the need for the exploration of these renewable energy at the same time integration of these energies to the national grid systems. Within these integrations, there are various effects caused by these moves that are both positive and negative though the advantages of the move overweigh the disadvantages caused n the human life. The effects are on the environment, cost and load balancing (Nair & Garimella, 2010).
Renewable sources of energy are considered very safe and are never depleted. They are found within the nature itself, and since nature will never cease to exist, and then these forms of energy will always be available for human consumption. The effect of these forms of energy is very vast. These are the forms of energy which do not pollute the environment and do not lead to any greenhouse effects. Due to the current global and ozone layer depletion, people are advised to turn to the renewable sources of energy that will help in maintaining the safe environment (Li & Wolfs, 2008). Consider solar energy or the wind energy, one just need the solar panels to tap the in tapping the sun's energy and use it in their houses, at the same time the other sources of renewable energy like hydro which only requires water in turning the turbines in generating electricity biomass is from the waste. These renewable sources of energy do not release any form of harmful materials to the environment and hence considered the best form of energy. It is this reason that makes it be the best form of energy needed by the world today (Lund, 2005).
On the contrary, these energies have got some very minimal negative effects on the environment. Considering the wind energy, the big turbines connected high up the grounds always rotate at very high speeds producing a sound that may cause noise pollution to the neighboring persons. At the same time, these turbines are a big threat to the birds as it is found that most of the time the birds’ passing around their point of installation are normally hit to death (Nair & Garimella, 2010). Solar energy also imposes some threat to the environment since the materials used in the making of the solar panels are sometimes considered not safe. Also, their installation affects the ecosystem of some living organisms since they need a very big piece of land for installation which may be home for some living organisms.
The cost of production and installation of these forms of energy is another area of concern. The Cost of renewable energies includes estimates of external costs and the cost of production. These costs go beyond the production costs as other costs including, for example, the cost of any necessary transmission capacity and reserve capacity in case of loss of generating capacity. Cost is a win-win situation and has both its advantages and disadvantages. The advantage is that most of the families can easily afford this form of energy since renewable energy is cheaper. Considering the biomass production that is generated from the waste of animals. Any family keeping animals in this case can bring up a biomass installation that is very cheap. Others like solar and wind are also cheaper in small quantities, but installation on the large scale may seem to be much expensive (Li & Wolfs, 2008).
Most of these form of energy like the solar and wind are in most cases located away from human being habitat because of the vast pieces of land they require. For the produced energy to reach the destined consumers may be in the urban areas may seem to be a bigger challenge that requires a large capital. The installations of the network connections from the source to the consumers requires a higher cost of production.at the same time, the transfer of these forms of energy from the points of production to the national grid may be much costly (Nair & Garimella, 2010). For this reason, the integration of these renewable forms of energy may be a big threat at a time to the government and on the contrary help in boosting the economy of the country. Improving the economy in that there will be cheap energy for the running of businesses and industries. Economic magnitude level impacts will vary by location but is expected to rise to higher penetration levels. Within the low penetration levels, operating reserve costs and balancing costs are found to be minimal.
Load balancing is a challenge affecting this sector of electricity integration. Most of the renewable sources of energy are to some extent unreliable. When the there is no sun, or when the wind does not blow, or there are low waters in our rivers. There is a need for balancing the amount of energy produced to prevent the irregular supply of energy during this times. Development of the storage system has made it easier for this irregularity since most of the grids have come up with storage systems. The storage system poses some disadvantage since the system is so much expensive and cannot be afforded by most of the grid managements. At the same time the use storage system is an advantage since the produced energy can still reach the consumers when the sun is low, wind not blowing and also when the rivers run dry since there will be stored energy. Load balancing is facilitated by a computing grid that is a virtual storage media and processing power (Li & Wolfs, 2008).
In general, the national electric grid is a complex network that is a main part of our society. Integrations into the grid of renewable energies are the way forward in solving the energy problem in most parts of the world in producing safe energy free from greenhouse gasses and harmful chemical that facilitated depletion of the ozone. The world today is geared towards conserving the environment. Whereas renewable power technologies will be a key part of our energy future, there is no one technology that can provide all of the energy and services we need. In the provision of reliable and mix power required in the supply of safe renewable electricity, there is a need for a careful integration of distributed generation and deployment of utility-scale generation.
