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, 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 ...

Impact of battery energy storage systems on the dynamic behavior of low-inertia power grids

Yihui Zuo

The extensive deployment of non-synchronous generation determines lower level of grid inertia resulting in deteriorated frequency containment performance and abnormal frequency excursions in case of contingency. This calls for identifying assets, controls, ...

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 ...

Design and experimental validation of an FPGA-based PMU simultaneously compliant with P and M performance classes

Mario Paolone, Asja Derviskadic

Low-inertia grids are characterized by high shares of harmonic and inter-harmonic distortion, produced by the inverters that interface non-conventional generation assets to the electrical grid. These interfering tones largely compromise synchrophasor estim ...

Decentralized and Distributed Transient Control for Microgrids

Alireza Karimi, Christoph Manuel Kammer

This paper presents a comprehensive approach toward the design of primary and secondary controllers in low-inertia power grids with mixed lines and a large amount of inverter-interfaced generation. First, a complete dynamic phasor model is developed that r ...

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 ...

Aspects of the energy transition and their effects on power systems

Laurent Vincent Pagnier

Most European countries are committed to an energy transition which consists in the substitution of conventional CO2 emitting energy sources by new renewable energy sources (RES), in particular wind and solar power. As opposed to conventional energy source ...

Decentralized and Distributed Transient Control for Microgrids

Alireza Karimi, Christoph Manuel Kammer

This paper treats the problem of primary and secondary control design in low-inertia power grids with mixed lines and a large amount of inverter-interfaced generation. A dynamic phasor model is developed that represents the electromagnetic and electromecha ...

Consensus algorithms and plug-and-play control for current sharing in DC microgrids

Giancarlo Ferrari Trecate

In this paper, we propose a secondary consensus-based control layer for current sharing and voltage balancing in DC microGrids (mGs). Differently from existing approaches based on droop control, we assume decentralized Plug-and-Play (PnP) controllers at th ...
