In order to measure the impact of substation interior on power system reliability under protection influence, a hierarchical power system which consists of equipment level, substation level and power system level is established. A stratified-sampling Monte-Carlo method is proposed based on Markov state space and functional decomposition. Probabilities of substation equipment states are calculated...
Research on the dynamic behavior of power system fault propagation is useful for understanding the evolution of system states, which can yield rapid awareness of the system operation state. An energy function model is established, which is based on power system dynamic equations, to extract the system energy information after a fault occurrence. The complexity of the evolving system energy flow is...
Bulk power transfer requirements over long distances within a country or between neighboring countries as well as rapid increase in the number of offshore wind farms, have increased the application of high voltage DC links. Apart from the controllable power flow function of HVDC systems, advanced controllers can be employed to extend their functionality for dynamic and transient stability improvement...
In this paper we propose to analyze the effects which errant or missing data may have on the stability analysis of a system during transient events, applying single machine equivalent (SIME) modelling for the analyses. As modern power systems are updated with the latest technologies, the deployment of PMUs is expected to increase the observability of the network both in real-time and for post-event...
In this paper, we propose the enhancement of existing power system stability analysis techniques through the use of a proposed set of potential energy indices, applied for observing the separation of generators into critical sets during transient events. This proposed potential-energy-based description of system transient stability behavior permits the formation of a critical generator cutset, which...
Bulk power transfer requirements over long distances within a country or between neighboring countries as, well as a large growth in offshore wind farms, have increased the number of high voltage DC links. Apart from the controllable power flow function of HVDC systems, advanced controllers can be employed to extend their functionality for dynamic and transient stability improvement of AC systems...
