Flexibility Management in Economic Dispatch With Dynamic Automatic Generation Control

As the installation of electronically interconnected renewable energy resources grows rapidly in power systems, system frequency maintenance and control become challenging problems to maintain reliability bulk systems. two most important actions centers independent operators (ISOs) utilities, interaction between Economic Dispatch (ED) Automatic Generation Control (AGC) attracts more attention. In this paper, we propose a robust optimization based framework measure flexibility by considering hierarchical processes (i.e., ED AGC). We cutting plane algorithm with reformulation technique obtain seven different indices system. addition, study impacts several factors budget operational cost, ramping capability, transmission line capacity) show numerically how these can influence flexibility.
