POWER SYSTEM OPERATION IN THE PRESENCE OF FLEXIBLE PROSUMERS CONSIDERING SYSTEM CONGESTION

Abstract

In this thesis, the optimal operation of the power system is studied using different objective functions: minimum total generation cost, minimum active power losses, minimum specific generation cost, minimum average energy cost. The effect of congestion on the voltage and reactive power output as well as the system performance is analyzed. The system performance is assessed through some key performance indices. Two IEEE benchmark systems which are IEEE 5-bus and 14-bus systems were used to test the formulations and algorithms. The model also includes variable loads and prosumers whose presence proved to be effective in dealing with power system congestion. The use of flexible loads and prosumers benefited the power system by reducing the system costs and losses. Additionally, the voltage profile of the system was enhanced.
