互联微电网多主体协同作用机理及能量管理优化方法研究

Driven by the power system deregulation and internet of energy, the interaction within the general uncertainties and all participants with different objectives in the interconnected microgrids makes the energy management more and more complex. First, the game theory is used to clarify the interactive behavior characteristics of microgrids and the interconnection parts in the background of the electricity market environment. By revealing the game mechanism among micro grids and among micro-elements within a single micro grid, the multi-participant synergy law is researched and obtained. On this basis, we study and quantify the characteristics of loads and output of renewable energy resources with confidence degree. Furthermore, power imbalance risk index is proposed in order to build the multi-participant synergy model of the interconnected microgrids. Combining model predictive control strategy and forecasting methods for renewable energy generation and load, convex optimization algorithm is researched and used to develop the energy management optimization method. Finally, by means of information transmission, a distributed optimization algorithm for energy management of the interconnected microgrids is built. As a result of considering overall and local interests, the interconnected microgrids can operate in an efficient and synergy manner. The research of this project can provide a new way for the energy optimization of the interconnected microgrids in China and promote the development of the interconnected microgrids.
