TECHNOLOGICAL DEVELOPMENTS IN ELECTRICAL MICRO-GRIDS

Electric market liberalization and environmental conditions configure a future guided to energy diversification, with significant increase in the use of clean energies and energy efficiency. This way, a tendency to the development of flexible and adaptable systems, with enough capacity to satisfy foreseen demand is configured. Thus, microgeneration is based on small power units, which are lower than 100 kW, placed in close locations to the consumption point. These sizes are quite small to be connected to local distribution systems, without requiring the connection to the transmission network. Furthermore, they can be installed in most of the commercial and residential buildings, universities, etc. This paper presents a revision of current developed technologies, which can be used for electrical microgeneration installations.
