Using Renewable Energy Systems ( Ac ) - 2416 Words

Summary: At present, most distributed renewable energy systems produce direct current (DC) electricity which is then inverted to alternating current (AC) and fed into the electric grid. Simultaneously, many modern building loads and storage systems use rectifiers to convert AC grid electricity to DC for use at the load or battery. Onsite use of renewable energy production therefore requires two energy conversions: DC/AC at the point of generation and AC/DC at the load. The Bosch DC Building Scale Microgrid Platform (DCBMP) offers significant benefits relative to conventional AC grid systems by distributing as much solar power as possible to DC loads/storage, and then inverting only the excess power to AC for AC loads and export to the grid. The DCBMP maximizes the utilization of solar energy on-site, smooths the volatility of the PV output, increases the load and storage efficiencies and minimizes dependence on grid-based electricity. The proposal incorporates long-life (20-25 year s), commercially ready technology, increasing energy efficiency and improving energy security. These features are provided at a low up-front investment when compared to conventional AC-based systems, enabling a levelized cost of electricity (LCOE) less than $0.14/kWh by 2020 for behind-the-meter PV and storage systems and a lower total cost of ownership for the DC loads and DC resources as compared to other approaches, while providing export power to the utility grid through smart inverterShow MoreRelatedUsing Matpower For Wholesale Power Management1518 Words   |  7 Pages Using MATPOWER for Wholesale Power Management Faizul Haque M.E (Eng MGMT) ENN590 – Project Submitted in partial fulfilment of the requirements for the degree of Master of Engineering (Coursework) Science and Engineering Faculty Queensland University of Technology October 2015 Acknowledgements I wish to express my gratitude and appreciation to my Project Supervisor Dr Yateendra Mishra, Course Co-ordinator Dr Dhammika Jayalath and Mechanical Co-ordianator Dr Wijitha Senaeera for theirRead MoreAlternative Energy: Solar Energy1323 Words   |  5 PagesIn the world today, alternative energy source which is an alternative to fossil fuel and nuclear energy is becoming more and more of a necessity. Right now, the world’s population growth has caused an increase in the energy demand. Rosenberg (2009) pointed out that the world’s current growth rate is about 1.14%, representing a doubling time of 61 years. OECDs International Energy Agency[IEA] (2014) found that from 2011 to 2035 the world energy demand is likely to rise by more than two-thirds.
