lCT -power Co-simulation Platform for the Analysis of Communication-based Volt/Var Optimization in Distribution Feeders

Description:
The paper presents an ICT and power co-simulation platform for the analysis of the voltlvar control and relevant optimization in medium voltage distribution feeders, achieved by means of a system of d... see moreistributed controllers coordinated via a shared band-limited digital communication network. The platform has been built by realizing the interface between two specific simulation environments:
the Electromagnetic Transient Program EMTP-RV and the communication network simulator Opnet Modeller. The preliminary results provide basic indications on the expected performances of the considered communication-based strategies for ditJerent tratlic congestion levels and load/generation dynamic variations.

Analysis of black-startup and islanding capabilities of a combined cycle power plant

Description:
The paper presents the analysis of black-startup and islanding capabilities of an 80 MW combined cycle power plant. The analysis is carried out by means of a computer dynamic simulator suitably develo... see moreped in the EMTP-RV simulation environment in order to represent both the power plant and the local network with the relevant loads. The paper describes the main characteristics of the implemented models and presents the analysis of transients due to both energization and islanding manoeuvres. The former simulations aim at verifying the feasibility of the energization of the path from a turbo gas unit, with autonomous black-start capabilities, to the local distribution network loads. The latter simulations allow the analysis of different islanding strategies for rather large levels of power exported to the external transmission network.

A Tool for Steady-State and Dynamic Analysis of PV Generation in Low Voltage Grids

Description:
Authors:
Dennetière S., Mahseredjian J., Duvauchelle C., Tounsi B.
This paper describes a tool based on EMTP-RV that simulates the steady-state and the dynamic behavior of photovoltaic (PV)... see more units on a low voltage grid. The tool takes into account load and irradiance curves to evaluate the impact of PV units on the voltage profile along the grid as well as the dynamic behavior of PV inverters. This tool has already been used to analyze and explain undesired disconnections of PV units in an existing system.

Induction machine modeling for distribution system analysis using initialization and time-domain methods

Description:
Panel session paper to be presented at the IEEE T&D show in New Orleans (Oct. 2005)
Authors: J. Mahseredjian, S. Dennetière, B. Khodabakhchian and A. Xémard
Abstract:
This pap... see moreer is presented as part of an effort by the Distribution System Analysis Subcommittee to establish reference cases for induction machine modeling in distribution system analysis and unbalanced three-phase systems. This panel paper presents analysis results obtained when applying a full time-domain method with load-flow and steady-state initialization. The selected software is EMTP-RV. Problem solution complexities are discussed.
