摘要:Transactive energy system (TES) is an electric infrastructure where the economic and control techniques are combined to manage the generation, power flow and consumption through transaction-based approaches while considering the reliability constraints of the whole system. TES ca...

摘要:Forced oscillation (FO) is a challenging problem as it could initiate power system instability due to resonance, especially when the frequency of FO and inherent electromechanical (EM) modes of power system coincide. Twin oscillation components (i.e. inter-area oscillation a...

摘要:With the increasing proportion of wind power connected to grid, power system dispatching is facing more and more challenges from uncertainty. To cope with this uncertainty, robust optimization has been applied in unit commitment (UC) problem. In this paper, a multi-band uncertain...

摘要:This study presents a multi-scale transient model of cascaded H-bridge (CHB) converter for distribution network-interactive studies, which is capable of simulating slow-changing dynamics up to high-frequency switching transients. The switching pulse behaviours of H-bridges are de...

摘要:In this study, sequential and simultaneous clearing of energy and reactive power markets are investigated. In the sequential clearing, a model is proposed for reactive power market clearing in distribution systems. In this model, by using lost opportunity cost concept for di...

摘要:Formulating power flow equations with linear sensitivity factors (LSFs) reduces the number of variables and constraints, and consequently, the computational burden of power systems’ optimisation problems. This study proposes a transformative, computationally efficient model ...

摘要:Solving power-flow (PF) problem of ill-conditioned systems is still a challenge in realistic power systems due to most of available techniques are quite inefficient. This study aims to address this issue by introducing a novel PF solution paradigm. It basically reformulates the t...

摘要:The penetration of distributed generators (DGs) of large capacities in micro-grid introduces a considerable difference of current seen by the relay, during faults in its primary and backup region. This leads to several issues with the protection system such as relay miscoordinati...

摘要:Partial discharge (PD) characteristics of the transformer oil contaminated by metallic particles are relevant to particle movement. The motion characteristics of the particles will change when the oil flows, and hence, the PD characteristics differ from that in stationary oil. In...

摘要:In the present Indian scenario, the real-time deviations are settled based on a deviation charge linked to average block frequency. This charge remains uniform across the country irrespective of the occurrence of congestion. Thus, it does not include the locational effect, which ...
