  7. Abstract:
  8. The objective of the present research work has been the development of a model of optimal distribution electrical energy which may include distributed generators. Electrical distribution company has the option of receiving electric power from distributed generators owned by customers (Private Companies), DGs belonging to the electrical distribution company and purchase of power from market (high voltage network). The electrical distribution company would alternatively be able to sell surplus of its generation to the power market (high voltage network). The model of distribution system depicts the flow of electricity in each hour interval. The restrictions and bounds are the flows in each level of the energy system have been considered and the objective function has been included to minimize the total operation costs. The model has been developed with the help of GAMS which is a tool for optimization. The model was applied for studying the behavior of a limited network which includes 13 buses and two DGs. One DG is operated by DISCO which has a capacity of 3 MW. The other with a capacity of 300 KW operated by a private company. It has been formed that energy losses in the network can be reduced by 8.5% at the peak hours
