A reduced-order, "grey-box" model of an active distribution network, intended for dynamic simulations the transmission system, is derived. The network hosts inverter-based generators as well static and motor loads, whose parameters are affected by uncertainty. This issue addressed using Monte-Carlo simulations. equivalent adjusted to match closely possible average randomized responses, while their dispersion accounted through weights weighted least-square minimization. procedure used remove...
An equivalent, i.e. a reduced-order model, of active distribution networks is derived, for use in (phasor-mode) dynamic simulations large-disturbances. In the unreduced network hosts large number inverter-based generators, responding to disturbances accordance with recent or near-future grid codes. The aggregated equivalent "grey-box" type and its parameters are tuned least-square sense match responses system several training disturbances. Changes operating point easily reflected when...
This paper deals with the derivation of dynamic equivalents active distribution networks, hosting inverter-based generators as well static and motor loads. Equivalents are reduced-order models for use in simulations transmission system. They grey-box types their parameters identified from large-disturbance Monte-Carlo accounting model uncertainty. After presenting an overview identification method at a single operating point, update equivalent when conditions network change. A procedure...
The analysis of the frequency response integrated transmission-distribution networks with deep penetration solar photovoltaic (PV) generation faces major challenges due to complexity emerging from dynamic models numerous and diverse PV units involved. This article proposes converter-based equivalent for both distributed (distribution network-connected) large-scale (transmission units, which take into account practical issues, such as measurement coordination delays. Different previous work...
This paper deals with the dynamic modelling of distribution systems hosting a large amount Inverter-Based Generators (IBGs), more precisely their response to disturbances in transmission system. It is assumed that individual behaviour IBGs and loads reasonably well captured by parameterized model, but values its parameters are uncertain. Monte-Carlo simulations involving random variations those performed. The closest average extracted as being representative. A simple procedure described...
A reduced-order model of a distribution network hosting inverter-based generators is derived. This aims to be used in dynamic simulations large disturbances the transmission system. Uncertainties affecting parameters component models are addressed using Monte-Carlo simulations. For given disturbance, average and standard deviation randomized system evolutions extracted. The equivalent "grey-box" type. Its adjusted match as closely possible response. involves minimizing weighted least-square...
The rapid uptake of renewable energy resources and displacement synchronous generators may pose threats to system frequency stability resilience. Starting from the August 2018 separation event in Australia, this work models discusses how utility-scale PV plants could contribute resilience islanded areas following events. In regard, a converter-based dynamic equivalent aggregated power is proposed which takes into account possible practical issues such as measurement coordination delays....
