The paper presents an important aspect in the research and development process of control algorithms of FACTS devices. It reveals the details of the time-optimal current control (TOCC) algorithm for STATCOM and deals with its implementation on the digital signal processor (DSP). It has been recognized that discretization of the control process within the DSP deteriorates the operation of the controller...
This paper presents hybrid power filter (HPF) performance evaluation procedure by applying special simulation hardware for digital real-time power system simulation (RTDS). RTDS simulator enables real-time calculation of electromagnetic phenomena with calculation time step of even 1–2 µs. Special hardware makes possible of importing and exporting of electrical signals from the simulator to external...
This paper presents an optimization approach in predictive control of voltage source converters (VSC). Basic predictive controllers are derived in discrete time domain and use the approximate mathematical models of the VSC based device to predict its electrical response. The proposed optimization approach, the time-optimal current controller (TOCC), predicts the state of electrical variables also...
The article presents a method for estimating the priority of new investments in distribution networks from a technical standpoint. The analysis focuses on overhead line-to-cable reconstructions which are due to the expected enhanced performance and quality very attractive for distribution companies. A comprehensive example based on an actual utility system is described in this article, and predictive...
