Approach for self-healing resilient operation of active distribution network with microgrid

Approach for self-healing resilient operation of active distribution network with microgrid Approach for self-healing resilient operation of active distribution network with microgrid Abstract: Self-healing capability as one of the most important features of smart distribution networks (SDN) causes an increase in the resiliency and flexibility of networks by responding fast and restoring service during an outage. A two-layer algorithm based on metaheuristics is proposed for the optimal operation of smart distribution network in self-healing mode considering microgrid (MG) and direct load control (DLC)…

A framework for incorporation of infeed uncertainty in power system risk-based security assessment

A framework for incorporation of infeed uncertainty in power system risk-based security assessment A framework for incorporation of infeed uncertainty in power system risk-based security assessment   Abstract— In this paper a risk-based security assessment (RBSA) methodology is presented which allows the assessment of operational security of a power system’s future state under uncertainty deriving from varying topology scenarios (contingencies) and forecast errors (loads and renewable infeeds). The methodology models input uncertainty with a copula function based Monte-Carlo (MC) framework. Further, it provides…

Interfacing Power System and ICT Simulators: Challenges, State-of-the-Art and Case Studies

Interfacing Power System and ICT Simulators: Challenges, State-of-the-Art and Case Studies Interfacing Power System and ICT Simulators: Challenges, State-of-the-Art and Case Studies   Abstract— With the transition towards a smart grid, the power system has become strongly intertwined with the information and communication technology (ICT) infrastructure. The interdependency of both domains requires a combined analysis of physical and ICT processes, but simulating these together is a major challenge due to the fundamentally different modeling and simulation concepts. After outlining these challenges, such as…

High-impedance fault detection in electrical power distribution systems using moving sum approach

High-impedance fault detection in electrical power distribution systems using moving sum approach High-impedance fault detection in electrical power distribution systems using moving sum approach   Abstract: High-impedance faults (HIFs) in electrical power distribution systems produce a very random, non-linear and low-magnitude fault current.nventional. the CoTovercurrent (OC) relaying-based distribution system protection schemes find difficulty in detecting such low-current HIFs. In this study, a simple two criteria-based protection scheme is proposed for detection and isolation of HIFs in multi-feeder radial distribution systems. It utilises one-cycle…
