英文摘要： This project intends to give a method of mathematical modeling and optimal control for distributed generation system. The aim is to set up the model system and the theoretical framework for optimal allocation and control of distributed generation system. The technology employed in this project include time sequence prediction technology, neural network, chaos theory and technology and so on. The main works and contributions are summarized as follows: 1) A prediction model of distributed generation system power is established. The maximum power point is tracked，which is the condition of transition between renewable and traditional energy sources. 2) The chaotic kinetic model is established for distributed generation system based on phase space reconstruction technology. The key parameters related to the system behavior are given based on the analysis of the mathematical model. The optimal parameter and configuration of the system are chosen. 3) A method of adaptive fuzzy neural network control is presented to realize optimal control for distributed generation system. The control rules based on the knowledge are expressed by fuzzy logic. The related parameters are adjusted based on the adaptability of the neural network. The research of this project will make deep thoughts of the internal action law of distributed generation system. The scientific analysis of distributed generation system is performed, including mathematical modeling, quantitative analysis and optimal control.
