State-of-the-art of data collection, analytics, and future needs of transmission utilities worldwide to account for the continuous growth of sensing data

Nowadays, transmission system operators require higher degree of observability in real-time to gain situational awareness and improve the decision-making process to guarantee a safe and reliable operation. Digitalization of energy systems allows utilities to monitor the system dynamic performance in real-time at fast time scales. The use of...

Intelligent Contingencgy Overload-Avoiding Control of BESS for Renewable-Rich Local Area

An N-1 contingency can negatively affect the reliability and security of electrical power systems. A single transmission line outage can cause overload on the local healthy transmission systems, and actions are required to alleviate the overload. Traditionally the system operator uses two actions depending on the operating local area power...

Modeling and Analysis of a Novel Grid Connection Topology for Offshore Wind Farms using MMC-HVDC Transmission

To meet the goals of the Paris Agreement, the Netherlands is integrating large amounts of offshore wind energy into the power system and has ambitious plans for the coming years. A grid topology with transmission capacity above 1 GW connecting offshore wind farms (OWFs) at distances close to 100 km in a standardized, modular, and cost...

Risk-based security assessment of transmission line overloading considering spatio-temporal dependence of load and wind power using vine copula

Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...

Controller to enable the enhanced frequency response services from a multi-electrical energy storage system

The increased adoption of renewable energy generation is reducing the inertial response of the Great Britain (GB) power system, which translates into larger frequency variations in both transient and pseudo-steady-state operation. To help mitigate this, National Grid, the transmission system operator in GB, has designed a control scheme...

Economic outage scheduling of transmission line for long-term horizon under demand and wind scenarios

A substantial increase in renewable energy in-feed to the primary grid as well as demand growth poses a challenge for transmission system operators (TSOs) to perform maintenance activities while addressing security of supply. A computationally efficient outage scheduling algorithm which is customizable in terms of area and time selection is...

Classification, domains and risk assessment in asset management: A literature study

This paper presents a literature study on asset management in electrical power transmission and distribution system. Due to restructure and deregulation of electric power industry in recent times, the focus has been on transmission and<br/>distribution assets that include transmission lines, transformers, power plants, substations and support...
