MMA, A Computer Code for Multi-Model Analysis

Eileen P. Poeter and Mary C. Hill - 2008

This report documents the Multi-Model Analysis (MMA) computer code. MMA can be used to evaluate results from alternative models of a single system using the same set of observations for all models. As long as the observations, the observation weighting, and system being represented are the same,...

Numerical comparison of the effects of different types of distributed generation units on overcurrent protection systems in MV distribution grids

Firouz, Y.; Farhadkhani, S.; Lobry, J.; Vallée, F.; … - In: Renewable Energy 69 (2014) C, pp. 271-283

The integration of distributed generation (DG) units into traditional distribution grids causes several significant changes in their characteristics like power flow direction, voltage profile and short circuit level. Therefore, the currently used control and protection strategies can no longer...
