With the increase of severe environmental pollution and the global greenhouse effect, it is inevitable to promote the low-carbon and clean transformation of energy consumption structure. Micro-energy networks with a high proportion of renewable energy are one of the most important methods to achieve the complementary use of renewable energy and fossil energy with high efficiency of energy utilization. Research on urban-level energy networks would be an important step for applying and integrating renewable sources.

With a high penetration rate of renewable energy, the robust ability and safety operation are challenging from both sides of energy generation and the electrical grid. Meanwhile, the increasing number of electrical and fuel cell powered vehicles put additional difficulties for optimization and scheduling. Therefore, research on urban energy systems with a high proportion of renewable energy is extremely valuable.

This topic aims to resolve the key problems existing in the integrated multi-energy network system for the urban level and provide a detailed theoretical basis and experimental data for the design and operation of integrated micro-energy networks at the international academic level. We welcome submissions on a wide range within the field of renewable energy systems, including modeling and optimization, grid supply, the interaction between grid and EV/fuel cell cars, and advanced controlling strategy of off-grid/grid-connected microgrid systems, etc.

The themes of this Research Topic include, but are not limited to:
1. Modeling, integration and coupling of multi-energy system
2. Efficient transformation and flexible control strategies for the multi-energy system based on the randomness of renewable sources
3. Optimal scheduling of off-grid/grid-connected microgrid system involving EV and hydrogen vehicles
4. Full life-cycle evaluation from perspectives of economic or energy flow
5. Demonstration project of urban micro-energy network system
6. Prediction based on the randomness of renewable sources/battery degradation
