英文摘要： Traditional grid scheduling mode has been difficult to adapt to the new smart grid environment with the rapid development of renewable generation, energy storage facilities, and flexible transmission network. There are a series of related unresolved challenging scientific and technical issues. In this proposal, we focus on the static economic dispatch, dynamic topology schedule and dynamic economic dispatch considering the uncertainty of renewable generation, energy storage and dynamic topology grid. We will present a model to descript the constraints with high- dimensional random vector and an algorithm to effectively reduce the number of integer variables in topology schedule problems, construct a more suitable economic dispatch model for smart grid environment, develop the optimization based methodologies for security constrained dynamic economic dispatch with multiple time scales, complex networked structure, and mixed decision variables. This project will make contributions in establishing theoretic foundations and developing practical methods for security, stability, efficient and economic operating of the new smart grid environment.
