Enhancing Resilience in Electric-Heat Combined System:Coordinated Approach for Transmission and Distribution Network During Ice Disasters
摘要
Abstract
Extreme ice-disasters during severe winter conditions in cold areas pose significant risks to basic power facilities,often leading to disruptions in heating services,particularly with the widespread adoption of electric-heat combined systems.To ensure uninterrupted power supply and heating services,alongside enhancing the resilience of electric-heat combined system against ice disaster weather,this study proposes a method that incorporates the coordination of transmission and distribution networks.Initially,a comprehensive load model for ice disaster conditions on transmission lines was established,and a fault scenario within the transmission network was generated using the Monte Carlo state sampling method.Subsequently,the composition and modeling of the electric-heat combined system pertaining to a concentrating solar power station were analyzed.Furthermore,a load-reduction model was constructed concerning the electric-heat combined system considering resilience improvement.Finally,the effectiveness of the proposed model was verified.The results demonstrated that the proposed strategy addresses both electrical and heat load requirements during ice disasters,significantly enhancing the resilience of electric-heat combined systems.关键词
