静态电压-功角稳定约束关键局部建模与运行优化
Modeling and Operation Optimization for Critical Parts of Static Voltage and Power Angle Stability Constraints
摘要
Abstract
The integration of high proportion of renewable energy poses challenges to the power system static stability.The non-analytical and highly non-linear characteristics of voltage-power angle stability constraints make optimization solutions difficult.However,such constraints can be approximately resolved within local regions.By focusing on these critical parts where stability constraints are active,the easily solvable analytical models can be constructed and embedded into the optimization process.On this basis,a modeling and operation optimization method for the static voltage and power angle stability constraints based on the critical part focusing is proposed.First,the method pre-solves the optimization model without considering stability constraints to identify an initial point,which guides the focus towards the critical parts of stability boundary.Then,the data-driven approach is used to construct a linear analytical expression to characterize the complex non-linear stability constraints within the critical parts.Finally,this expression is embedded into the operation optimization model for solving,coupled with a constraint correction strategy to guarantee system stability.Case studies validate that the proposed method can meet the requirements of static stability while ensuring economy,and has good computational efficiency.关键词
