Expansion planning of transmission networks

Expansion planning of transmission networks

Transmission networks play an inevitable role in secure and effective operation of power systems. This role calls for well-organized and comprehensive procedures that are designed to be used in operational and expansion of these complicated networks. In this regard, many different frameworks and optimization algorithms have been introduced to deal with the complex nature of transmission expansion planning (TEP) problem. Moreover, recently some events including presence of renewable energy resources in generation sector and deregulation of power systems have intensified the complexity and randomness of TEP problem. Therefore, some strategies have been employed to handle the uncertainties in these studies. Among, stochastic, robust models, and hybrid (robust/stochastic) models have been introduced as effective tools to untangle the complexities experienced in TEP studies of renewable-based power systems. This chapter focuses on application of these techniques in TEP problem.
