Abstract
The aim of transmission network expansion planning (TNEP) is providing enough capacity to transfer power from generation section to load centers in a reliable and economically efficient manner. The mission of this problem is identifying where, when, and what type of new transmission lines should be installed in transmission network. In this chapter, the robust TNEP (RTNEP) in the presence of two major uncertainties in power systems (loads and wind power generation) is studied. The robust methods of (a) information-gap decision theory (IGDT), (b) Taguchi’s orthogonal array testing (TOAT), and (c) scenario technique criteria (min-max regret criterion) are proposed and simulated here. Using each of these methods, the robust expansion plan for the modified 6-bus Garver transmission network test system is calculated. The obtained results verify the validity of the mentioned methods in RTNEP. These methods can easily be implemented on any large- and real-scale power system. Furthermore, different uncertainty types can be easily considered in this regard.
