Special Issue Information

Dear Colleagues,

The innovation and utilization of sustainable energy is considered to be the solution to the energy crisis. By reducing the reliance on fossil fuels, sustainable energy can reduce greenhouse gas emissions and slow climate change. However, the use of sustainable energy still faces challenges, such as the cost of technology, control and consumption of energy, energy storage, and the construction of energy infrastructure. With continued innovation and investment, sustainable energies are expected to become an important part of future energy supply.

Against this background, virtual power plants are a new type of power plant that can realize the effective management of sustainable energy and demand-side response resources connected to the grid, and it is an effective way to achieve the sustainable development of power systems. On the basis of making full use of communication, metering and control technologies, combined with blockchain, artificial intelligence, and other technologies, virtual power plants aggregate renewable energy and demand-side response resources, and participate in electricity market transactions in the form of aggregates, providing technical support for the digital transformation of the power system. As an important part of building a clean, low-carbon, cost-effective, flexible and intelligent sustainable development of a new power system with supply–demand synergy, virtual power plants provide solutions for the sustainable development of energy.

This Special Issue focuses on contributions addressing the challenges in optimization and operation control for sustainable virtual power plants with renewable energy. Topics for the Special Issue include, but are not limited to, innovations and finds in the following areas:

  1. Emerging technology of sustainable energy generation technology;
  2. Emerging technology of future smart grids;
  3. Emerging technology of sustainable energy systems;
  4. Optimal planning and operation methods for virtual power plants;
  5. Emerging artificial intelligence techniques for sustainable energy systems;
  6. New power generation control technology of grid-forming converters;
  7. Emerging wireless power supply technology for new power systems.

We look forward to receiving your contributions.

The increasing installation of Renewable Energy Sources (RES) presents significant challenges to the stability and reliability of power systems. This paper introduces an advanced control method to mitigate the adverse effects of intermittent generation from RES on the power system frequency stability. The proposed approach emphasizes the critical role of Battery Energy Storage Systems (BESS) and RES in enhancing the resilience of modern power networks. The Generation Export Management Schemes (GEMS) are employed to curtail the excessive export of RES, thereby contributing to improved frequency stability. This research involves a comprehensive analysis of the dynamic behavior of the network under various operational scenarios, particularly focusing on power exchanges between RES, BESS, and synchronous generation units. Furthermore, this paper focuses on the economic implications of integrating RES into the grid, with a detailed cost of balancing (COB) modelling and analysis conducted to assess the financial viability of the proposed frequency management solutions. The analysis encompasses both short-term and long-term perspectives, providing insights into the development of economically sustainable smart power networks that effectively integrate renewable energy and storage technologies while maintaining system stability.

After a traditional one-time rocket is launched, most of its parts will fall into the atmosphere and burn or fall into the ocean. The parts cannot be recycled, so the cost is relatively high. Multi-stage rockets can be recovered after launch, which greatly reduces the cost of space launches. Moreover, recycling rockets can reduce the generation of waste and reduce pollution and damage to the environment. With the reduction in rocket launch costs and technological advances, space exploration and development can be carried out more frequently and economically. It provides technical support for the sustainable use of space resources. It not only promotes the sustainable development of the aerospace field but also has a positive impact on global environmental protection, resource utilization, and economic development. In order to adapt to the stage-by-stage separation structure of the rocket, this paper proposes a new multi-stage rocket inductive power transfer (IPT) system to power the rocket microgrid. The planar coil structure is used to form wireless power transfer between each stage of the rocket, reducing the volume of the magnetic coupling structure. The volume of the circuit topology structure is reduced by introducing an auxiliary coil. An equivalent three-stage S/T topology is proposed, and the constant voltage output characteristics of multiple loads are analyzed. A multi-stage coil structure is proposed to supply power to multiple loads simultaneously. In order to eliminate undesired magnetic coupling between coils, ferrite cores are added between coils for effective electromagnetic shielding. The parameters of the magnetic coupling structure are optimized based on the finite element method (FEM). A prototype of the proposed IPT system is built to simulate a multi-stage rocket. A series of experiments are conducted to verify the advantages of the proposed IPT system, and the three-stage rocket system efficiency reached 88.5%. This project is theoretical. Its verification was performed only in the laboratory conditions. Full article
