A Control Method for Converter-interfaced Sources to Improve Operation of Directional Protection Elements

Yang, Zhe (author), Liu, Zhou (author), Zhang, Qi (author), Chen, Zhe (author), de Jesus Chavez, Jose (author), Popov, M. (author)

The traditional fault control strategy of converter-interfaced renewable energy sources (CIRESs) may bring about a lower sensitivity level or misoperation of fault component-based directional elements. To overcome this problem, a new control scheme is proposed to adjust sequence impedance angles of CIRESs by computing suitable current...

Optimal design of multi-energy systems with high shares of renewable energy sources: A linear-programming approach for integrating electricity, heating, and hydrogen sectors in multi-energy systems

Feijen, Sven (author)

The large-scale integration of variable renewable energy sources (VRES) brings about challenges related to the stochastic characteristics in supply. In this light, a recent and promising approach which has received increasing attention is that of multi-energy systems (MES). A MES is defined as an energy system whereby different energy sectors...

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

Sanchez, Francisco (author), Cayenne, Joshua (author), González-Longatt, Francisco (author), Rueda, José L. (author)

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...
