风/生物燃料互补分布式供能系统理论与方法研究

Wind energy and bio-energy resources are abundant in Guizhou Province. This project aims to implement a wind-biofuel-energy storage based distributed energy system. The key issues will be investigated, including system planning, controlling and reliability evaluation. The main contents in the study are: 1. System implementation and modelling. Single mode and mixing mode of these multi-source will be investigated where the principle and the specific states will be summarized prior to the mathematical/analytical models being developed. Where one or more specific prediction methods will be selected for modelling and model revision. 2. The relationship between multi-energy storage systems and wind-biofuel supply system. We will also investigate the principle and methodologies as the energy demands are integrated or shifted or allocated by integrating energy from different energy storage systems. 3. The framework and the mathematical models of the coordination control for the system. We will also explore the potential solutions with consideration of both calculation efficiency and accuracy. 4. Reliability evaluation for the multi-source distributed energy system. We will try to find out the critical conditions and security standards for this energy system. Anti-interruption and robustness of the system with the assistance of the energy storage will be assessed. This project will combine theoretical analysis, computational modelling with hardware-in-the-loop tests. We expect to develop the systematical methodology and principal theory for the optimal utilization of the local energy resources. Therefore, the research outcomes will promote the interests of the renewable energy systems.
