Abstract [en]

In power development technology there are pioneering various μ-grid concepts, that integrating multiple distributed power generation sources into a small network serving some or all of the energy needs of participating users can provide benefits including reduced energy costs, increased overall energy efficiency and improved environmental performance and local electric system reliability. In the fast progression of technology the electric vehicles, electric construction equipment and machinery such as- road building or quarries would greatly benefited from electrification and the by this revolutions, they able defending the environment from detrimental effect and potential energy (and local emission) reduction is sufficient. These types of sites are often remotely located and it is much costly to meet the high voltage utility grid or distribution grid, which are normally far-off from the sites. Hence, it would be advantageous to be able to set up such sites without having to build long and expensive connections to high voltage transmission and distribution grids. In this project we have design and proposed a self-sufficient smart DC micro-grid providing renewable energy resources to supply electric machinery is designed. This grid is capable of meeting energy as well as peak power demands of machine site while offering the possibility to fully rely on locally produced renewable energy. In this project we have included price and performance forecasting for solar and wind energy, charger, grid energy storage system and micro-grid power electronics. Therefore, with this design it is capable to provide efficient power supply to the site and can meet the demand at peak loads. Grid modeling and simulating results (including loads, storage and energy production) are done by MATLAB.
