Short-term Dispatch of Renewable Sources Considering Minimization of Active Losses and Generation Costs

The global search for diversification in energy matrix associated with technological developments has led to an increase in the participation of renewable sources, requiring the redesign of models for planning and operation. In this context, this paper proposes a short-term dispatch considering the presence of wind and solar plants, where the power for renewable sources is allocated according to historical load profiles. The mathematical modeling of the algorithm is performed via AMPL considering two different objective functions: (1) minimization of active power losses and (2) minimization of electricity production costs. The interior point method from Knitro is used to solve the model. Tests on the IEEE-30 bus system with real generation data from wind and solar power farms of the Brazilian Electrical grid highlight the method's capability in providing an adequate and coherent short-term dispatch in the presence of renewable generation.
