>>>Special Issue Information
Power grids are as important to society as blood vessels are to the human body. Traditional power grids are passive and centralized, with unsatisfactory energy utilization rate and flexibility. On the one hand, it is difficult to cope with the daily increasing distributed power supply, and on the other hand it is difficult to adapt to the rapidly changing demand for electricity and storage. Expanding the capacity and coverage of power grids in the traditional mode will place greater pressure on the environment, and face higher and higher marginal costs. Microgrids are an ideal solution to further improve the scale, coverage, efficiency, and flexibility of power grids. They are generally small power generation and distribution systems composed of a distributed power supply, energy storage device(s), energy conversion device(s), load, and monitoring and protection devices. They can realize the flexible and efficient application of various distributed power sources, such as solar energy, wind energy, hydropower, small generators, etc., realizing an active distribution power network and transforming a traditional power grid to a smart grid.
The Isle of Eigg, a small island 10 miles off the Scottish west coast that can hardly be reached by traditional power grids, is enjoying the benefit and convenience brought by a microgrid. In Bihar, India, a low-cost microgrid is providing electricity to more than 4000 rural households with low income. In China, rapidly increasing electric vehicles are being used as a new type of distributed mobile energy storage in microgrids to help the power grid to absorb the surplus electricity within it and to smooth the impact of power fluctuations. The emergence of microgrid clusters provides a more efficient and environmentally friendly solution for collecting distributed energy supply and solving random distributed electricity demand. The world’s microgrid capacity is expected to see a rapid increase in the coming years.
However, there are still obstacles to be overcome before microgrids can fully exert their capacity. The power sources in microgrids are complex and have different characteristics, which require unified coordination and management. Because of the different structures and characteristics between the microgrid and the backbone grid, it is still a difficult problem to transmit the surplus power in the microgrid to further places through the backbone grid. The interconnection and interaction between microgrids and the joint networking are also the bottlenecks of their application. Therefore, it is especially necessary to conduct in-depth research on these issues.
At present, academic and business circles have put forward some methods to improve the efficiency of microgrids and their networking characteristics, such as droop control technology, distribution algorithm improvement, intelligent distribution network planning methods, cooperative control methods, bird swarm algorithm, etc. Correspondingly, the software and hardware technologies supporting microgrids are also rapidly developing, although these methods and techniques are still far from mature.
Therefore, we are launching this Special Issue titled “Dynamic Interconnected Microgrids” and call for papers from scholars and enterprises all over the world, hoping to collect the most advanced research results at present, stimulate the collision of thinking, enlighten innovation, and make contributions to the further development of microgrid technology. The scope of this Special Issue includes but is not limited to the following:
Configuration of power source, loading, and storage in self-balancing microgrids;
Microgrid interconnection control technology;
Application of flexible connection and rigid connection in microgrid clusters;
