With high penetration of renewable generation and distributed energy resources, distribution
systems are facing new operational challenges due to their intermittency and uncertainty. To …

Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

This paper proposes an optimal day-ahead optimization schedule for gas-electric integrated
energy system (IES) considering the bi-directional energy flow. The hourly topology of …

Extreme natural disasters can seriously disrupt power systems. The increased damage
intensity of natural disasters also leads to synchronous failures in communication systems …

The effective use of the flexibility sources of transmission and distribution networks
necessitates smooth coordination between transmission and distribution system operators …

The risk of transmission overload (TO) in power grids is increasing with the large-scale
integration of intermittent renewable energy sources. An effective online preventive control …

With the increasing interconnection of active distribution network (ADN) with the integration
of distributed generations (DGs) and district heating network (DHN), local electricity-heat …

This paper deals with the provision of primary frequency response (PFR) as ancillary service
(AS) from active distribution networks (ADNs) to the transmission system (TS). In particular …

Abstract Distributed Generations (DGs) with Electric Vehicles (EVs) now play a key role in
the planning of power distribution systems. The integration of DGs with EVs planning in the …

The increasing number of renewable energy sources (RESs) connected to power grids
contributes to the emergence of not only balancing problems but also technical ones, such …
