Sinusoidality Index
J. Gutiérrez Florensa, L. Sigrist, Á. Ortega +1
Maintaining sinusoidal or near-sinusoidal operating conditions in electrical systems is essential, as is their accurate assessment. This letter proposes a novel metric, namely the…
Theoretical and Experimental Limitations of RoCoF Estimation
Gutierrez-Florensa, F. Sanniti, D. Tedeschi +3
A precise estimation of the Rate of Change of Frequency (RoCoF) is crucial for secure power system operation. In fact, RoCoF is strictly related to the amount of the available phys…
Quasi Steady-State Frequency
Joan Gutierrez-Florensa, Alvaro Ortega, Lukas Sigrist +1
Accurate frequency estimation is critical for the control, monitoring and protection of electrical power systems, in particular, of systems with a high penetration of power electro…
Modeling Demand Flexibility of RES-based Virtual Power Plants
Oluwaseun Oladimeji, Alvaro Ortega, Lukas Sigrist +3
In this paper, an approach to evaluate the benefits of demand flexibility for Virtual Power Plants (VPPs) is presented. The flexible demands chosen in this study are part of a rene…
Optimal Participation of Heterogeneous, RES-based Virtual Power Plants in Energy Markets
Oluwaseun Oladimeji, Alvaro Ortega, Lukas Sigrist +3
In this work, we present a detailed model of a Renewable Energy Source (RES)-based Virtual Power Plant (VPP) that participates in Day-Ahead Market (DAM) and Intra-Day Market (IDM)…
Generalized Model of VSC-based Energy Storage Systems for Transient Stability Analysis
Álvaro Ortega, Federico Milano
This paper presents a generalized energy storage system model for voltage and angle stability analysis. The proposed solution allows modeling most common energy storage technologie…
