Power supply interruptions to final customers are mainly caused by failures in the distribution system. The increase of distributed generation connected to the distribution system offers a possibility to reduce the duration and frequency of such interruptions as local generation can be used to feed local demand. This paper presents results of an actual implementation of an islanding operation for...
In this paper it is proposed a methodology for simulating the behavior of electrical distribution networks, with the presence of intermittent sources of energy, based on a computational environment integrating power system static and dynamic simulation. The methodology represents an improvement over the simple implementation of power flow cases for different points of time series representing the...
This paper addresses the evaluation of total transfer capability in hydro-dominated power systems focusing on the Brazilian interconnected power systems. The methodology currently adopted by the Brazilian national system operator to compute transfer limits is presented. A methodology that automatically integrates optimal power flow, transient, small-signal and voltage stability simulation is also...
This paper presents a Power System Stabilizer (PSS) tuning procedure based on a Parallel Genetic Algorithm (PGA). The procedure is applied to the simultaneous tuning of 61 PSSs, using their actual models in the entire Brazilian Interconnected Power System (BIPS) modeled with 3849 buses. Heavy, median and light loading conditions were considered during the tuning process, to ensure control robustness...
