“…shows the energy and power demand for the province of Galapagos until 2027, with values of 100.068 MWh [17]. The strati ed tank is divided into ten segments for analysis, in which the highest temperature is at the top in the segment called "Upper segment" and the lowest temperature at the bottom in the "Lower segment" [19]. From the upper segment, the uid with the working temperature is conducted to the steam generation system.…”

This chapter presents an hourly energy management system (EMS). The hybrid renewable energy system (HRES) is composed of a hybrid ae-generator system (WT), solar photovoltaic (PV) panels, a diesel generator (DG) and a distributed collector system (DCS) as the primary energy source. The distributed collector system (DCS) consists of a field of parabolic trough collectors that carry solar thermal energy to a power conversion unit to produce electricity, an energy storage system (ESS), the wind turbine, the PV panels and the distributed control system (DCS) are made to work at the maximum power point, while the battery acts as storage. The energy management system (EMS) uses intelligent rule-based controllers to meet the energy demanded by the load and maintain the state of charge (SOC) of the battery between certain target ranges. The controller implemented for this study is a fuzzy logic controller that mimics human understanding of various phenomena that may occur during microgrid operation. The simulation results show that the fuzzy logic-based control meets the objectives established for the energy management system (EMS) of the hybrid renewable energy system (HRES).

“…For this purpose, the challenges of IMGs can be studied in different fields. Smallsignal modeling and stability analysis of AC IMGs through circuit breakers (Shahnia and Arefi, 2017;Nikolakakos et al, 2016;Shahnia, 2016;Rehimi et al, 2020;Yao et al, 2021), modeling and stability analysis of AC IMGs through back-to-back converters (Naderi et al, 2019b(Naderi et al, , 2020bSinha et al, 2021;Majumder and Bag, 2014), power oscillation damping and frequency stability enhancement (Nikolakakos et al, 2016;Hossain et al, 2016;Hirase et al, 2020;Ali et al, 2021), and stability improvement by the interlinking devices and DERs control (Zhang et al, 2016;Hao et al, 2018), are the main aspects of the IMGs stability recently studied in the literature. Power exchange control of IMGs is another important issue, which is based on the stability analysis and studies (Wu et al, 2019;Hossain et al, 2016;Golsorkhi et al, 2018;Zamora and Srivastava, 2018).…”

“…NMG system under a two-layer control framework is becoming a new trend but few works are reported to analyze the delay-dependent stability of such framework under multiple time delays. [5] derives a delay-dependent stability criterion under a two-layer distributed control algorithm, but only a single delay is considered. Similarly, the impact of a single delay on NMG is investigated in reference [31].…”

“…Although MGs have been demonstrated as a promising solution to integrate the distributed DERs, on certain occasions such as large disturbances or power restorations after disasters, a single MG system may not ensure system stability due to limited generation capacity and specific geographical boundaries. To enhance the entire system's reliability and resiliency, one promising solution is to integrate multiple MGs to form an NMG system [5]. The NMG can effectively control and coordinate different MGs with a high penetration of DERs scattered at diverse locations.…”

“…Considering a single MG has a limited generation capacity and specific geographical boundaries, the networked-microgrid (NMG) system is proposed 2 by interconnecting multiple MGs to enhance its resilience against extreme events [5]. Compared with a single MG, NMG introduces a sophisticated cyber-physical system that contains various components such as distributed DERs/sub-MGs, electrical networks, heterogeneous and spatially distributed communication, and controllers.…”

supervisor, Assoc. Prof. Xu Yan, for his guidance, encouragement, and advice. It has been a great privilege and joy to study under his guidance and supervision. His rigorous academic attitude, infectious enthusiasm, and gentle personality always inspire me in my research and life journey. It is him who makes my Ph.D. journey fulfilling, and it is also him who always encourages me to explore life's possibilities. The limited words hardly express my deep feelings, but I still want to say the Ph.D. journey under his supervision is the best time of my life. Also, I would like to thank my co-supervisor at NTU, Assoc. Prof. Tan Rui, my mentor, Prof. Wang Peng, and my co-supervisor at the Technical University of Denmark, Assoc. Prof. Wu Qiuwei. They provide very valuable suggestions and guidance and give me many supports in my Ph.D. journey. Dr. Wang Yu, Research Fellow of EEE, NTU, has my heartfelt gratitude. He always supports me when I was in tough situations. The research experience shared by him inspires me to pursue more in this field. He teaches me a lot about the detailed algorithms, models, skills, and knowledge, and I really enjoyed the time discussing research issues with him. He is an excellent academic role model for me, and his steady, practical, diligent, and modest qualities will always be worth my lifelong learning.Moreover, I also want to thank my seniors and colleagues, Dr.
