Microgrids are expected to become part of the next electric power system evolution, not only in rural and remote areas but also in urban communities. Since microgrids are expected to coexist with traditional power grids (such as district heating does with traditional heating systems), their planning process must be addressed to economic feasibility, as a long-term stability guarantee. Planning ...

In this paper, Multi-Microgrids (MMG) are considered as future smart distribution grids, in which small scale energy resources (SSER) are main power generation units with small scales. Optimal operation of microgrids in defined intervals is carried out to achieve economic conditions in distribution systems. The defined operating problem is optimized using a heuristic algorithm considering uncer...

Microgrids are becoming increasingly attractive to consumers and as such in the future, a great number of them will be installed at consumer’s sites. In this situation, conventional distribution networks that accept distributed generation connections may face serious difficulty when its control and protection functions become more complicated. This incurs a burden to the network operation and s...

In this paper, the effect of a static synchronous compensator (STATCOM) influence on the frequency of islanded microgrids based on frequency control using fuzzy cooperative control is investigated. To achieve fast frequency control, instantaneous power balance between generation and consumption is inevitable, and it can be supplied through energy storage systems such as battery with a proper fr...

the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

Subscriber service is not feasible in the construction of large-scale traditional networks with the aim of providing more services. The high distance between production and consumption requires the definition of a transmission network as a challenging intermediary. The cost of transmission network and the risk associated with it cannot be ignored at all. The idea of a microgrid, which began wit...
