Modeling and MPC Based Control of Line Power Flow in Smart Grid

Constraints to expand the infrastructure of the transmission system, penetration of the renewable that has huge uncertainty in generation leading to congestion on the system. The conventional way of removing congestion on the line by the operator takes a long time, i.e., about 5–20 mim, which is too slow for the transmission network. One of the ways to eliminate the congestion automatically within less time is to use the controller. For real time line flow control, this paper proposes Model Predictive Controller (MPC) considering constraints on the SM (Synchronous Machine) and power system frequency deviation; SMs are appropriately dispatched based on Generation Shift Factor (GSF). The controller has been evaluated in the 68 bus test system. The controller showed better performance than the conventional techniques and could track the line flow in less time, i.e., about 60s.
