With the increasingly coupling of the electric power system with coal/gas/thermal/water supply systems, the energy supply of smart urban system will be undertaken by an integrated energy supply system. Intelligent green building and smart grid are the two major subjects for the development of integrated energy system, of which the optimal operation and control are both inseparable from energy storage.
Energy storage system can effectively store different forms of energy, reduce the coupling degree between energy production and absorption, and improve the flexibility of energy production and system operation. Compared with the conventional battery storage system, multi-form energy storage can efficiently and flexibly realize the conversion between multiple energy sources, and is the key link of the future integrated energy supply system. Therefore, it is necessary to study the configuration and optimal operation strategy of the multi-form energy storage system and its application in intelligent green buildings and smart grids.
In order to solve the problem of photovoltaic energy absorption with high penetration in smart urban buildings, a new thermal/cooling absorption system integrated in intelligent buildings is proposed. It uses phase change energy storage to meet the cooling and heating demands of power users, and also improves the load distribution characteristics of integrated energy communities and promote the economy effects of renewable generation and consumption. Focusing on the difficulty of flexible transportation and consumption of energy resources in pelagic islands, an energy transmission network based on all-electric vessels is proposed, the vessels are equipped with large capacity battery energy storage system and can flexibly load and unload batteries. In addition, to solve the problem of the consumption of renewable energy in regional energy networks, a comprehensive optimal dispatching strategy of coal-wind-hydrogen energy network is put forward considering the efficiency of hydrogen energy storage.
