Performance assessment of grid-forming and grid-following converter-interfaced battery energy storage systems on frequency regulation in low-inertia power grids

Mario Paolone, Fabrizio Sossan, Yihui Zuo, Sidi-Rachid Cherkaoui, Antonio Zecchino, Zhao Yuan

Power systems with large shares of converter-interfaced renewables may be characterised by low grid inertia due to the lack of frequency containment provided by synchronous generators. Battery energy storage systems (BESSs), which can adjust their power ou ...

Effect of voltage source converters with electrochemical storage systems on dynamics of reduced-inertia bulk power grids

Mario Paolone, Fabrizio Sossan, Yihui Zuo

A major concern associated to the massive connection of distributed energy resources is the increasing share of power electronic interfaces resulting in the global inertia reduction of power systems. The recent literature advocated the use of voltage sourc ...

Grid-Supporting Battery Energy Storage Systems in Islanded Microgrids: A Data-Driven Control Approach

Alireza Karimi, Reza Razzaghi, Behrooz Bahrani

Islanded microgrids have low real and reactive power generation capacity and low synchronous inertia. This makes them susceptible to large frequency and voltage deviations caused by switching of large loads or equipment failures. These events deteriorate p ...

Synchronized Sensing for Wide-Area Situational Awareness of Electrical Grids in Non-Stationary Operating Conditions

Asja Derviskadic

Situational-awareness methods and technologies are crucial elements to ensure power systems reliability and security as they are used by automated decision-making processes of mission-critical applications. Inadequate system monitoring results in incorrect ...

Real-Time Control Framework for Active Distribution Networks Theoretical Definition and Experimental Validation

Lorenzo Enrique Reyes Chamorro

The great challenge of massively integrating the volatile distributed power-generation into the power system is strongly related to the evolution of their operation and control. The literature of the last decade has suggested two models for such an evoluti ...

STUDY AND IMPLEMENTATION OF “DROOP CONTROL” METHODS FOR INTERFACING VOLTAGE SOURCE INVERTERS TO MINIGRID

Philippe Barrade

This contribution presents control methods for the regulation of the voltage and the frequency on AC minigrids, fed by voltage source inverters (VSI). In order to avoid a complex communication network for the synchronization of the various VSI on a minigri ...

Turbine Speed Governor Parameters Validation in Islanded Production

François Avellan, Jean-Jacques Simond, Philippe Allenbach, Christophe Nicolet, Basile Kawkabani, Bob Greiveldinger

The transient behavior of hydroelectric power plants is of high interest for ensuring stability of islanded electrical power networks. Therefore, it is suitable to determine and validate the set of parameters of a turbine speed governor using a realistic s ...
