“…The Santo Tomé HVDC converter is the second DC link asynchronously dependent on the power systems of Argentina and Brazil. The Santo Tomé back-to-back high-voltage DC (HVDC) link control design is presented in the paper [422]. Besides HVDC control functions, the Santo Tomé converter station also has an LFC function.…”

Load frequency control (LFC) is one of the most important tools in power system control. LFC is an auxiliary service related to the short-term balance of energy and frequency of power systems. As such, it allows the acquisition of a central role in enabling electricity exchanges and providing better conditions. The classification of LFC can be carried out from different angles: we can enumerate, among others, the type of control used. The following types of control are presented in this review: classical, optimal, and robust control. More advanced controls can also be used for classification: fuzzy logic control, ANN control, genetic algorithms, PSO control, etc. The influence of renewables and power control tools like FACTS is also considered as a category to be analyzed. The last classifications are related to two important subjects—the influence of DC links on LFC efficiency and the dangers of cyberattacks on the LFC.

“…Some recent studies analyse the impacts of battery energy storage (BES), photovoltaic (PV) power generation, capacitive energy and wind turbine on the performance of the LFC system or their application in power system frequency control [7,[134][135][136][137][138][139][140][141][142][143]. Considerable research on the LFC incorporating an HVDC link is contained in [144][145][146][147][148].…”

This paper presents a load frequency control scheme using electric vehicles (EVs) to help thermal turbine units to provide the stability fluctuated by load demands. First, a general framework for deriving a state-space model for general power system topologies is given. Then, a detailed model of a four-area power system incorporating a smart and renewable discharged EVs system is presented. The areas within the system are interconnected via a combination of alternating current/high voltage direct current links and thyristor controlled phase shifters. Based on some recent development on functional observers, novel distributed functional observers are designed, one at each local area, to implement any given global state feedback controller. The designed observers are of reduced order and dynamically decoupled from others in contrast to conventional centralized observer (CO)-based controllers. The proposed scheme can cope better against accidental failures than those CO-based controllers. Extensive simulations and comparisons are given to show the effectiveness of the proposed control scheme. Index Terms-Distributed functional observers (DFOs), high voltage direct current links, linear functional observers (LFOs), load frequency control (LFC), state observers, thyristor controlled phase shifters (TCPSs), vehicle-to-grid (V2G). NOMENCLATURE LFC Load frequency control. EV Electric vehicle. AC Alternating current. HVDC High voltage direct current. TCPS Thyristor controlled phase shifter. FACT Flexible alternating current transmission. BESS Battery energy storage system. V2G Vehicle-to-grid. LRO Luenberger reduced-order observer. LFO Linear functional observer.
