Analytical frequency-constrained UC for island power systems
Rouco Ferriz, Almudena; Rajabdorri, Mohammad; Lobato Miguélez, Enrique; Sigrist, LukasThis paper presents a frequency-constrained unit commitment (FCUC) formulation for island power systems. The timely activation of spinning reserve is key to guaranteeing frequency stability in the operation planning phase. ... -
Frequency stability assessment of deloaded wind turbines in Spanish island power systems
Fuente Pascual, Delia; Rajabdorri, Mohammad; Lobato Miguélez, Enrique; Sigrist, LukasThis paper investigates under what circumstances the provision of frequency regulation by renewable energy sources can provide technical and economic benefits to real island power systems. In order to do so, the unit ... -
Impact assessment of FCUC on optimal design of UFLS settings in Island Power Systems
Lobato Miguélez, Enrique; Sigrist, Lukas; Rajabdorri, Mohammad; Egido Cortés, IgnacioA frequency constrained unit commitment (FCUC) formulates the non-linear, non-convex frequency dynamics to obtain the generation dispatch of island power systems (IPSs). Even with FCUC, under frequency load shedding (UFLS) ... -
Practical solutions to limit computational burden of UC in Island Power Systems
Lobato Miguélez, Enrique; Sánchez Martín, Pedro; Rajabdorri, Mohammad; Sigrist, LukasUnit commitment (UC) models used in real-life island power systems (IPSs) require complex modelling details and low execution times since they have to be launched repeated times for different assumptions and changing ... -
Robust frequency constrained UC using data driven logistic regression for island power systems
Rajabdorri, Mohammad; Lobato Miguélez, Enrique; Sigrist, LukasIn the current practice of short-term power scheduling, online power reserves are used to address generation mismatches and contingencies. Neither online inertia nor the speed of the committed units is considered in the ... -
System-wide benefits of renewable-based virtual power plants in island power systems
Rajabdorri, Mohammad; Sigrist, Lukas; Ortega Manjavacas, Álvaro; Lobato Miguélez, EnriqueRenewable Energy Sources (RESs) have experienced significant growth in recent years. RES-based Virtual Power Plants (RVPPs) allow aggregating smaller RES-based Distributed Generators (DGs). This paper presents a system-wide ... -
Viability of including frequency metrics in short-term scheduling of island power systems
Rajabdorri, Mohammad; Lobato Miguélez, Enrique; Sigrist, LukasIn the current practice of short-term power scheduling, reserve power is used as a tool to address generation mismatch and contingencies. The practice is starting to fall short especially in smaller power systems, as the ...
