Optimal transmission network expansion planning in real-sized power systems with high renewable penetration

摘要

The deregulation of power markets and the high amount of renewable energy expected in the coming decades have originated new needs for the expansion of the transmission network. Transmission expansion planning (TEP), the problem that deals with identifying the optimal grid reinforcements, is therefore becoming increasingly relevant. TEP, notoriously difficult to solve, is also deeply affected by uncertainty in factors such as renewable generation. Approaches for TEP based on optimization have not been widely used given that their high computational requirements mean that they could not be efficient for large-scale, real systems.
