Abstract:This review presents a state-of-the-art literature review of Automatic Generation Control (AGC) control strategies for power systems containing renewable energy sources. The incorporation of renewable energy into the power system has a large impact on the stability, reliability, economy and security of the power system. To mitigate these effects, it is important to choose a suitable control strategy for AGC. However, there is a limited amount of literature available on the review of AGC in renewable energy pow… Show more
“…In addition, we have introduced a significantly improved version of the "LFC and cybersecurity" section to insert articles that are relatively poorly known but interesting. Among other valuable comprehensive reviews, there are a few that tackle the problem of LFC in general [60][61][62][63], but most of them present specific research fields like the influence of deregulation on the LFC problem [64,65], LFC and diverse energy sources [66], LFC and renewables [67][68][69], LFC and smart grids [70], LFC, soft computing and optimization techniques [71,72], and LFC and the stabilization of signals in multiarea systems [62].…”
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.
