考虑可再生能源接入的多能源站稳态安全域分析
Steady State Security Region Analysis of Multi-energy Station Considering Renewable Energy Access
摘要
Abstract
An integrated electricity-heat energy station model is established,which systematically captures the energy demand of each energy station,electrical loads,active/reactive power outputs from photovoltaic units,network topology configurations,and relevant technical parameters,including line resistances and reactances.Operation constraints are constructed to ensure system meets its operational requirements,with safety operation boundaries for the coupled energy system concisely formulated.The steady-state safe region is subsequently derived through rigorous mathematical derivation processes,where renewable energy fluctuations are comprehensively accounted for using probabilistic power injection models.Furthermore,it can ensure the maximum energy supply capacity of the entire system,even in the event of a failure of one device within the energy station fails.Based on the operation constraints of the coupled system and the representation of the steady-state safe region,the quasi-gradient system(QGS)method in nonlinear dynamical systems is employed to explore a comprehensive representation of the steady-state safe region in nonlinear dynamical systems.Subsequently,the numerical trajectory unification(TJU)method of non-hyperbolic dynamical systems is used to calculate the boundary of the steady-state safe region for non-hyperbolic dynamical systems.This paper can effectively represent the steady-state safe region of a multi-integrated energy station and demonstrates considerable certain robustness,significantly reducing the errors associated with traditional methods.关键词
