The environmental advantage of distributed energy resources (DERs) application has attracted lots of research attention and encouraged to implement clean power producers. In spite of the environmental benefits of renewable energy sources application as distributed power generation, the variability of renewable energy, e.g. wind power uncertainty, can potentially endanger the operation of electric power system. This paper presents a new techno-economic factor (TEF) for DERs based on the effect of their generation on network losses and the relationship between active/reactive power loss and generated power from thermal power plants. In order to simultaneously investigate these new factors and wind power uncertainty on power network operation, a stochastic Security Constrained Unit Commitment (SCUC) for 24 h is defined consisting of generation and emission costs. The simulation results of IEEE57-bus case study show the effective role of RES application on operational cost minimization. (c) 2012 Elsevier Ltd. All rights reserved.
