Abstract
Power is a very important instrument to the development of economy of a nation and it must be stable and available and to meet the demand of the consumers at all times. The quest for power supply has introduced a new technology called microgrid. Micro grids are regarded as small power systems that confine electric energy generating facilities, from both renewable energy sources and conventional synchronous. Generators, and customer loads with respect to produced electric energy. It can be connected to grid or operate in islanding mode. On the other hand, the grid’s dynamics and its stability rely on the amount of stored energy in the micro grid. In a conventional power system with a large number of synchronous generators as the main sources of energy, the mechanical energy in the generators’ rotors, in the form of kinetic energy, serves as the stored energy and feeds the grids in the event of any drastic load changes or if disturbances occur. Microgrid is an alternative idea to support the grid, it can be applied in a street, estates, community or a locality (towns and villages), organizations and establishments. Load forecasting can be further extended to Organizations, Local Government, State and country to determine the energy consumption.

Power supply is becoming more complex as a result of increasing population, expansion and development in some locations
Modern micro grids are regarded as small power systems that confine electric energy generating facilities, from both renewable energy sources and conventional synchronous generators, and customer loads with respect to produced electric energy (Smallwood, 2002)
Reliability, availability, conservation and optimization can be guaranteed by aggregating the generators in three proposed power houses
Summary
Power supply is becoming more complex as a result of increasing population, expansion and development in some locations. Modern micro grids are regarded as small power systems that confine electric energy generating facilities, from both renewable energy sources and conventional synchronous generators, and customer loads with respect to produced electric energy (Smallwood, 2002) They can be connected to the main grids or operated as isolated power systems (Katiraci et al, 2005). 2) The campus microgrids: they are fully interconnected with a local electricity network, but at the same time, they can independently keep and provide some level of service in isolation from the grid, like in the case of a utility outage. Some examples of this category are university campuses, military bases. 4) The nanogrids: they consist of the smallest discrete network units with the capability of independent function, as it can happen in a single building
