At present, human society is developing rapidly. The consumption of resources increases year by year, not conducive to future scientific and technological progress and leads to significant environmental damage. Therefore, it is crucial to promote the transition from fossil fuels to renewable energy during the progress. As a critical component to the transition process, energy storage devices are increasingly concerned from academia, making significant progress. Among these energy storage devices, the lithium-ion battery has become the most widely used, benefiting from its high energy density and long cycle life. However, serious problems such as inadequate safety, high costs, and severe environmental pollution have been exposed with the deepening development. On such a basis, developing an energy storage device more in line with the current development is necessary. Aqueous zinc-ion batteries have become a popular candidate for the next generation of energy storage devices due to their high electrochemical performance, ensured safety, low expense, resource abundance, and environmental friendliness. In this section, the material design from anode, cathode, and electrolyte perspectives are primarily focused on. The working mechanisms are concluded based on the introduction of applied materials. The section serves as the fundamentals for further introduction to flexible aqueous zinc-ion batteries.
Operational Planning of Electrical Power Systems and Smart Grids
Published in B K Bala, Energy Systems Modeling and Policy Analysis, 2022
To ensure energy security and reduce pollution due to production and the use of energy, a gradual transition to renewable energy is advocated. The real challenge to the power industry does not lie in a 100% efficient renewable energy source but in how to integrate several types of energy sources into the grid that are less predictable. Renewable energy sources such as wind and solar could be directly connected to the grid. Communication systems are crucial technologies for grid integration of renewable energy resources. Two-way communication is the fundamental infrastructure that enables the accommodation of distributed energy generation and assists in the reconfiguration of network topology for more efficient power flow. The communication infrastructure is considered the fundamental element that allows the monitoring and control of the operation of renewable energy systems. In addition, it enables the transfer of both measured information and control signals between the renewable energy systems and the control center (Yu et al., 2011). There are several communication options available for the grid integration of renewable energy resources. These options include a hybrid mix of technologies such as fiber optics, copper-wire lines, power-line communications, and a variety of wireless technologies.
Modular Systems for Energy and Fuel Transport
Published in Yatish T. Shah, Modular Systems for Energy Usage Management, 2020
In general, the transition to 100% renewable energy systems is an important factor in making energy systems sustainable. The transition path toward 100% renewable electricity supply has been analyzed for many countries such as Denmark, Portugal, Macedonia, Croatia, China, and New Zealand. Morvaj et al. [23, 24] evaluated the use of modular microgrid for renewable energies. The main scope of this study was to assess the feasibility of using the heat demand of buildings as a function of outdoor temperature for renewable energy in the electricity grid supply. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district consists of 665 buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and variable renovation scenarios were considered.

The growing global population and increasing energy demands pose significant challenges to existing energy supplies, making the transition to renewable energy sources a necessity. In this case, some available renewable energy technologies can be used based on the feasibility of certain locations. Solar energy can be regarded as one of the most prominent alternatives to fossil fuels due to its widespread availability. Furthermore, biomass, another sustainable energy source, can generate a significant amount of energy that can be used in different locations. Considering the limitations of biomass and solar energy, hybrid solar and biomass power plants are being deemed as pioneering technology for overcoming the disadvantages of both systems. The first section of this paper focuses on the utilization of solar energy in solar power plants. Generally, Concentrated Solar Power (CSP) and photovoltaic power (PV) plants are the two most prevalent methods for utilizing solar energy (Mohaghegh et al. 2021).
A State-of-the-Art Review on Electric Power Systems and Digital Transformation
Published in Electric Power Components and Systems, 2023
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.

Development in renewable energy as the main source of electricity production in the near future is becoming increasingly important in most countries around the world taking in mind the goal of combating global climate change and GHG reductions bound by the Paris Agreement COP 21. Renewable energy is at the heart of the transition to a more sustainable and less carbon-intensive energy system. However, renewable energy sources such as wind, solar, and tidal waves all rely on intermittent resources depending on factors such as climate, weather, and construction sites. Therefore, the integration of these resources in the current electrical system (power grid) faces considerable challenges. To ensure the reliability and stability of the power supply, it is necessary to supplement the power source reserve system with multi-billion-dollar investment costs.
