The structure and behavior of Electrical Grids share many of the properties of Complex Computer Systems, with microgrids and other decentralized electrical systems attached to them, so they can be interpreted as Systems of Systems. Furthermore, the evolution of the future electrical system will bring a higher degree of decentralization concerning specially production and control. To deal with t...

Smart power grids are transitioning towards effective employment of distributed energy resources including renewable sources to address the growing environmental concerns related pollutant emissions fossil fuels.

A microgrid is composed of distributed power generation systems, distributed energy storge systems, loads as a small scale power system. Generally, the microgrid is operated by an energy management system (EMS). In this paper, a testing technique for a microgrid EMS using the hardware-in-the-loop simulation (HILS) technique is introduced. Especially, the microgrid is composed of multiple buildi...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...

Now a days, renewable energy resources such as solar Photo Voltaic (PV) cells, fuel cells (FC) and wind turbines(WT) plays an important role in generating electricity nearer to local loads that are integrated to utility grid. For integration of distributed energy resource converters to utility grid, a synchronization i.e matching of frequency, phase, amplitude of output voltages, active power a...

We consider the optimal power management in renewable driven smart building MicroGrid under noise corrupted conditions as a stochastic optimization problem. We first propose our user satisfaction and electricity consumption balanced (USECB) profit model as the objective for optimal power management. We then cast the problem in noise corrupted conditions into the class of expectation maximizing ...
