Many restructured power markets rely on Financial Transmission Rights (FTRs). FTRs are financial contracts that entitle the holder to a stream of revenues (or charges) based on the day-ahead hourly congestion price difference across an FTR related energy path. Holders obtain FTRs through an auction mechanism relying on the solution of a specially formulated OPF problem. FTR holders then receive or...
Transmission topology control (line switching) is currently practiced with manual and ad-hoc based actions by ISO control room personnel who rely on a combination of past experience and a fixed data set of line openings linked to various congestion patterns. Our previous work used sensitivity information from the solution of a DC economic dispatch problem to develop topology control algorithms that...
Following up on our previous work, we formulate a linear, loss-adjusted, shift factor mixed integer program (MIP) to co-optimize generation and network topology. While both the B-theta and shift factor topology control (TC) formulations lead to production cost saving, we showed that the shift factor formulation performs better for small to medium switch able sets. In this paper we extend the original...
The standard economic generation dispatch (ED) minimizes generation costs subject to transmission constraints, where the status of each line, i.e., open or closed, is fixed. Recent research shows that, by optimally dispatching the network topology along with generation resources, significant congestion costs may be avoided. Optimal topology control, i.e., appropriate changes of transmission-line status,...
Transmission topology control (TC) is currently employed by power system operators for reliability, e.g., in special protection schemes, rather than for economic reasons. The standard economic generation dispatch (ED) minimizes generation costs subject to a fixed transmission network topology. Although the co-optimization of network topology and generation resources results in significant congestion...
The standard optimal power flow (OPF) problem minimizes generation costs over one study period assuming a fixed system topology. The prospect of a smart grid incorporating extensive cyber capabilities enabling significant progress in economic efficiency, reliability and environmental sustainability, ought to transform the OPF problem accordingly. This paper discusses the inclusion of tractable dynamic...
