Criteria development and assessment models for technical, economic and commercial Distributed Generation aiming Virtual Power generation

The selection of generation projects is based on the amount of energy consumption in the expected growth of demand in the amount of operating reserves and needs to regulate the system. A viable solution to meet energy needs and expansion of systems is the Distributed Generation - DG. Single source of DG does not guarantee economic generation, reliability, flexibility and controllability in energy markets. This paper presents a methodology considering DG as an advantageous alternative in the energy markets and technical and economic benefits to distribution systems. It is proposed that the aggregation of sources in Central DG “Virtual” Power, making them economically competitive within the markets for electricity. The control and supervision of this plant will be conducted by the Operation Center of the concessionaires. The tool is a complement to programs for expansion of distribution systems.
