Stability Constrained Day Ahead Unit Commitment with Maximizations of Spinning Reserve for A PV Embedded Electric Grid

Unit commitment grows to be a complex issue because of the restructuring of the power system and the escalation of the inclusion of different types of distribution generation sources are increasingly restricted. These sources are significantly lower than conventional sources. They also synchronize grid problems as electricity cannot be transmitted over long distances and therefore deliver localized energy consumption. In this paper, unit commitment (UC) has been carried out with the integration solar photovoltaic (PV) into the power system with optimum allocation of spinning reserves and an assessment of reliability and load loss. The `Loss of Load Probability' (LOLP) index is used to determine the reliability level of the results obtained in UC calculations, the Spinning Reserve (SR) is a constant value and is not differing in terms of variation in the solar generation. Here, the analysis has been carried out for measuring the optimal spinning reserve with respect to the power injection variation. The integration of solar energy into the power system, two systems (four generators and ten generating systems) uses dynamic programming techniques and compares the results with the results obtained without considering optimal LOLP, SR and solar energy sources.
