Resilience Enhancement Strategy of Combined Heat and Power-Virtual Power Plant Considering Thermal Inertia
摘要
Abstract
The increasingly frequent extreme weather has a more serious impact on the electro-thermal coupling system.Resilience is a core indicator that measures the system's ability to withstand extreme events,reduce the impact of failures,and recover quickly.To enhance the ability of the electro-thermal coupling system to withstand extreme disasters,a two-stage three-layer resilience enhancement strategy of combined heat and power-virtual power plant(CHP-VPP)considering thermal inertia was proposed.In the first stage,the system was reconstructed based on the minimum spanning tree theory with the goal of minimizing the cost of tie switches.In the second stage,aiming at minimizing the operating cost,the optimal decisions under the worst failure scenario was formulated based on distributionally robust optimization theory.The column and constraint generation algorithm was used for iterative solutions.A CHP-VPP test system was built based on an IEEE 33-bus system and a 6-node thermal system.The simulation results show that the proposed method can effectively enhance the resilience of CHP-VPP to cope with extreme disasters.关键词
