چکیده :

Nowadays, the uncertainty in the power system parameters has led to more operator flexibility requirements. Flexibility is the ability of the system to deal with uncertainty and balance the supply-load equilibrium. This study presents an optimal operation model of distributed generation resources to supply electrical and thermal load as a virtual power plant for participating in the electricity market. Normalized up-ward and down-ward flexibility indices (FI) are expressed for demand response programs, conventional generators, and energy storage systems. Additionally, by assigning weights to each of the above indices, the up-ward and down-ward FI of the whole system has been calculated. The model has been evaluated on the standard 33-busses IEEE distribution system. The results demonstrate that the proposed flexibility model can quantify the system's flexibility so that the system operator has an adequate view of the system's hourly flexibility.
