INTEGRATED HYBRID MICROGRID - THE CELL OF FUTURE DISTRIBUTION NETWORK

Sustainable development of energy system is considered on a new basis by creation of distribution network in the form of microgrid containing distributed sources - renewable and traditional. In microgrids renewable sources as solar plants, wind mills, biogas units, energy accumulation units and some others are used in combination with such traditional power sources as diesel generators, small gas turbines. Rated power of microgrid sources is designed to cover local demand. The studied combined microgrid has connected to the main grid. Taking in consideration the high price of power conversion equipment the efforts were made to minimize their number. Modeling of combined microgrid, results of steady state evaluation and analysis in different operation conditions are considered.
