Evaluation of the reliability parameters in micro-grids based on renewable energy sources is one of the main problems that are investigated in this paper. Renewable energy sources such as solar and wind energy, battery as an energy storage system and fuel cell as a backup system are used to provide power to the electrical loads of the micro-grid. Loads in the micro-grid consist of interruptible...

A micro grid consists of cluster of loads and distributed generators that operate as a single controllable system. As an integrated energy delivery system micro grid can operate in parallel with or isolated from the main power grid. The micro grid concept introduces the reduction of multiple reverse conversions in an individual AC or DC grid and also facilitates connections to variable renewabl...

In this paper the connotation and the different definition of micro-grid were expounded, the basic structure of micro-grid was described, and the key technologies of smart grid were expatiated on. Finally, the directions for future research in our country of micro-grid are elucidated.

This paper Describe a feasible operation of micro grid. The micro grid is the combination of multiple distributed generators to solve global warming problems by reducing carbon dioxide emission in the electricity generation field had led to increasing interest in micro grids (MGs), particularly those containing the renewable sources such as solar and wind generation are widely used in actual pr...

Although photovoltaic power plants are suitable local energy sources in Micro Grid environments, when large plants are involved, partial shading and inaccurate modelling of the plant can affect both the design of the Micro Grid as well as the energy management process that allows for lowering the overall Micro Grid demand towards the main grid. To investigate the issue, a Photovoltaic Plant sim...

This paper describes the implementation of Multi Agent System (MAS) for advanced distributed energy management of a solar micro-grid. We consider a grid connected solar micro-grid with two solar Photo Voltaic (PV) systems, and each system contains a local consumer, a solar PV system and a battery. First we measure the load patterns and solar power generated in the two solar units. Then we use M...

Few years ago Power Systems consisted mainly of large generation plants supplying distant loads through the utility grids. The last years, though, a number of factors lead this structure to change gradually. Small generators of some MW have been already dispersed (DGs) throughout the transmission grid. The distribution of smaller generation units throughout the distribution system as near as po...
