Metodología para despacho económico a corto plazo aplicado en plantas virtuales de generación basada en políticas energéticas

Abstract

The evolution continues in consideration of a growth in demand at a global level, where new technologies will influence the objectives of electrical power systems because at present, they are not able to provide the energy required by users, becoming a problem for increased operating costs and losses in electrical systems. To manage, improve and optimize the operation of the systems, guaranteeing their support, visibility and economic stability within the energy markets, a virtual power plant (VPP) is implemented combining several distributed generation units. For the existing problem of economic dispatch, not only energy compensation (supply and demand) should be considered, but also the energy production restrictions of DERs. Dispatch through the distributed gradient algorithm seeks cost reduction, easy implementation, greater flexibility and robustness considering the energy policies implemented for the use of unconventional resources, focusing on energy efficiency and managing equality and inequality restrictions. The IEEE 14 and 30 bus models to be studied present 3 proposed scenarios. In this way, it is verified that the methodology used allows us to progress analytically in relation to other works, demonstrating high stability and convergence.
