Introduction
Published in Evanthia A. Nanaki, George Xydis, Exergetic Aspects of Renewable Energy Systems, 2019
Energy is essential to all human activities as well as critical to social and economic development. Currently, the majority of energy systems are based on fossil fuel consumption leading to climate change and air pollution. Reducing energy use and increasing energy efficiency are crucial aspects for urban areas such as cities. Taking into consideration the fact that the worldwide population is growing, it is predicted that the fossil fuel consumption will keep on rising until 2050 [IEA energy outlook, 2017]. In this direction, many policies, such as the Paris Agreement, have been established. The Paris Agreement is characterized by a bottom-up approach to global cooperation, where each country delivers national inventories of greenhouse gases (NIR) and prepares Nationally Determined Contributions (NDC), which have to be adjusted and strengthened every five years [Doelle, 2016].
Energy and Environmental Development in Maldives

The greatest obstacles for the transition from fossil fuel-based energy systems to renewable energy systems perhaps could be the convenience of fossil fuel (Wijayatunga et al. 2016). However, at the same time, it is worthy to mention that, in the modern world, climate change is a strong driver to encourage countries to cut back on their usage of fossil fuel. The uncertainty surrounding climate change is driving countries to adopt renewable energy technologies to reduce carbon emission. However, both mature and emerging economies still largely demand energy-intensive sources and services, especially to generate electricity. Emerging economies are completely dependent on fossil fuel-based energy systems; in these economies, the convenience of fossil fuel-based energy systems remains deeply engrained in all the societal domains and practices. Therefore, the transition will be harder in emerging economies, compared to matured economies (Wolfley 2018). Transition is a complex process with a huge number of driving factors and impacts that involves markets, networks, institutions, technologies, policies, individual behavior and autonomous trends. The key message we are learning here is that even though renewable energy systems have many advantages, the transition from renewable energy to fossil fuel-based energy systems will take time to accomplish (Loorbach and Verbong 2012). What is certain is that even though there is no simple solution for an energy transition, a transition is inevitable to countries such as the Maldives where climate change and energy insecurity threatens the development of the Maldives.
Introduction
Published in B K Bala, Energy Systems Modeling and Policy Analysis, 2022
Energy systems consist of energy supply, energy demand, price, climate change and environmental quality to facilitate the better supply of energy with minimum impact on climate change and environmental quality. To ensure energy security and reduce contributions to global warming, the transition to distributed systems, i.e., renewable energy, is essential. To meet the electrical energy requirements of tomorrow in a sustainable manner, today’s central system should be gradually moved into distributed utility, which is essentially a hybrid system to minimize emissions and maximize reliability. Figure 1.14 shows such a distributed utility.
A State-of-the-Art Review on Electric Power Systems and Digital Transformation

As seen from the brief SWOT analysis given in Table 2, the integration of renewable energy sources into the electric power system is a critical trend that will help to reduce greenhouse gas emissions, diversify energy sources, and improve the reliability and stability of the power system. While there are significant challenges associated with this integration, such as the need for effective energy storage solutions and improved grid integration, these challenges are being addressed through the development of new technologies and techniques, such as advanced control systems and energy storage systems [71]. With continued advances in these areas, the future of renewable energy sources looks bright, and the transition to a more sustainable and resilient energy system can be achieved.

As a result, generating power using locally accessible renewable energy sources might be a viable choice in microgrids or electricity-scarce areas. Furthermore, the electricity produced by a renewable energy system has a storage concern that can be countered using battery banks (Patil, Saini, and Sharma 2011). Renewable energy sources and storage technologies might be used to create a conventional self-sustaining hybrid energy system. In such hybrid systems, several aspects such as the total cost of the system, the size and capacity of renewable energy sources all play a role (Bhattacharjee and Dey 2014). Two critical factors, such as the cost of generating energy and the system’s reliability, are essential concerns in such systems. The best component selection should be made while retaining system dependability in an ideally designed system (Singh and Kaushik 2016).

Renewable energy sources become safer, economical, and pollution-free in the smart grid AC/DC power system. Renewable energy resources include solar photovoltaic arrays, wind energy, and hydro energy systems. This approach contains five major components: solar photovoltaic array, hydro turbine, wind turbine, battery storage unit, and interconnected load. The modeling process is easily identified the entire component characteristics. The performance prediction is obtained through this modeling. The whole performance of the modeling is validated by either the deterministic approach or the probabilistic method. The performance validation of the solar photovoltaic system, wind energy, and hydro system is as follows.
