以电力-天然气-热能为核心的微能源网分层优化控制策略研究

Integrated with multiple energy forms such as electricity, natural gas and thermal energy, microgrid is capable of improving the efficiency of multiple energy sources including renewable energy, which is an important development direction of the future energy supply and consumption system on the customer side. Energy systems in microgrid are different in operational characteristics and time scales, and coupled with each other strongly. Therefore, it is difficult to conduct management through a centered and static manner. This project focuses on hierarchical optimization of control strategy for electricity-natural gas-heating dominated microgrid. In the first place, comprehensive modeling method for operation control of microgrid would be studied, including comprehensive integration modelling for microgrid and predictive modeling for specific energy systems in microgrid, which is the foundation of hierarchical optimization of microgrid control. After that, optimal dispatching technology would be developed to reach the optimal dispatch of the energy in microgrid. Then, interaction technology between customer load and microgrid would be researched to offer more control options for control optimization of microgrid. Based on all the above researches, hierarchical optimization of control strategy would be developed. Specifically, optimization hierarchy would be established, and hierarchical control optimization method would be developed. The results of this project would improve the operation control level of microgrid, enhancing the development of microgrid and achieving high efficiency of energy utilization.
