Unit Commitment in a dispersed power system involving renewable energy

This paper presents a common approach for the unit commitment problem solving in a dispersed power system involving renewable energy sources on the example of Kazakhstan. The proposed methodology will help all interested organizations and structures to see the possibility of covering the shortage of power generation capacities by increasing the share of renewable energy sources in generating electricity and their parallel work with the existing generation facilities instead of commissioning of traditional energy sources. Also, according to this methodology, there is a possibility to choose the optimal source of renewable energy and the possibility of testing the operation of a part of the dispersed power system, as autonomous. This methodology includes the analyzing of impact of the regional and global energy trends, legislation and the potential for renewable energy sources. The numerical results show the possibility of solving the problem of unit commitment with renewables with the least operating costs and with the most optimal renewable energy source type in the region.
