Iterative, or negotiated, pricing mechanisms have been of interest for decades as a systematic means of operating electricity markets, and have more recently been proposed as a way of dealing with the increased diversity of responsive market participants brought about by smart grid technologies and the increasing share of intermittent energy sources. One possibility is for the market coordinator to...
This work deals with the control of VSC-HVDC using wide area measurements. The goal is to enhance the transient and oscillatory stability of the power system for example during inter area oscillations or after faults. To this end, we present a predictive control framework that dynamically manipulates both the active and reactive powers injected by the VSC-HVDC links in a grid of generators, lines...
For a large number of single input-single output (SISO) typically used in the process industries the Internal Model Control (IMC) design procedure is shown to lead to PID controllers, occasionally augmented with a first order lag. These PID controllers have as their only tuning parameter the closed loop time constant or equivalently, the closed loop bandwidth. On-line adjustments are therefore much...
