Integrated renewable systems

Abstract

Today, the world's energy supply is largely based on fossil fuels and nuclear power. These sources of energy will not last forever and have proven to be one of the main causes of our environmental problems. In the long term Renewable energy will necessarily dominate the world's energy supply System. Energy demand all over the world is growing rapidly. In order to meet the demand and at the same time to achieve sustainable development objectives on a global scale, conventional approach to meet the energy requirement must be reoriented toward energy systems based on renewable energy and energy efficiency, which will make it possible to address social, economic, and environmental concerns simultaneously. Due to their decentralized character, renewable generations offer quick solutions in large scale energy supply structures and networks. Geographical diversity adds to the capacity credit for Renewable. Large balancing areas & shorter dispatch period may reduce problems in Renewable integration. Heavy administrative approval procedures, existing market structures with a dominant position of the Conventional Energy, a widely diffused underestimation of the potential of renewable and a lack of incentives are some of the factors that slow down the growth of renewable energies. If Regulatory supports and desirable incentives for investment are provided then Renewable Energy contributions will be increased. The cost of the renewable energy technologies themselves, the lack of access to affordable credit, the costs of connecting with the grid and transmission charges often penalize intermittent energy sources. Variability, Intermittent and Uncertainty of Renewable resources are the challenges in Integration & concerns to System Operator. A good short term forecast is a pre-requisite for successful market participation by a Renewable generator.
