Optimal unit commitment decision with risk assessment using tabu search

This paper presents a methodology based on the tabu search (TS) approach to unit commitment decision (UCD) considering risk constraints, in order to reduce the total operation cost of power systems. In this paper, a risk assessment model is developed to keep the security of power systems, and the TS is used to make the optimal decision of unit commitment for power provider system. Finally, the method of the paper has been tested on large-scale practical power system (Tai-Power System), to indicate its high potential and practical values.
