It was recently observed that a significant gap exists between the costs of Transmission Network Expansion Planning (TNEP) solutions produced by the DC power flow approximation and AC power flow heuristics. This paper confirms the existence of that gap and shows that DC-based TNEP solutions exhibit significant constraint violations when converted into AC power flows. The paper then demonstrates how...
The aim of this project is to develop a dynamic model of distribution network cell (DNC) using artificial intelligence approach. The increasing number of distributed generation (DG) technology has lead to difficulty in modeling the DNC model. The simple load modeling is no longer reliable in presenting the DNC model. In this project, the equivalent dynamic model of DNC consists of the converter-connected...
Local controllers are essential in distribution networks; they are employed in classical devices such as load tap-changing (LTC) transformers and switchable shunt capacitors, and more recently in distributed generation (DG). The effective use of distribution management system (DMS) applications requires an accurate model of the interaction between the local controllers through the distribution system...
For a long time, the research about the impacts of reactive power compensation devices on reactive power margin and voltage stability in power system has been important. Under the electrical market environment, the reactive power margin computation becomes even more necessary. By adopting the idea of heuristic energy function, this paper formed the energy models of two-bus and multi-bus system. Based...
