Abstract

The proliferation of smart grid technologies in distribution systems allows unlocking the ability of distributed energy resources to provide services not only to distribution system operators (DSOs), but also the transmission system operator (TSO). This evolving paradigm calls for the development of new tools accounting for the coupling of transmission and distribution systems. Within this context requiring the joint consideration of both systems, this paper addresses the investment planning problem faced by a TSO. Unlike previous TSO/DSO integrated approaches, the DSO's reaction against the TSO's expansion plans is explicitly modeled while considering that both entities are driven by their own goals. To that end, we propose a novel stochastic bilevel programming framework to deal with this hierarchical decision-making process under uncertainty. As another salient aspect, three different instances are analyzed, each associated with a practical operational scheme for interface nodes and distribution substations. The resulting bilevel programs are handled by a new approach where the upper and lower levels are solved sequentially. In contrast to the standard transformation to a single-level equivalent, the proposed solution technique is suitable for problems lacking convexity in the lower level. Numerical results from two case studies illustrate the performance of the proposed approach.
