Embodiment 1
[0025] This embodiment discloses a post-disaster recovery control method for a resilient distribution network based on an electric-gas integrated energy system. The specific implementation process is as follows figure 2 As shown, on the basis of ensuring that most of the loads in the elastic distribution network can resume power supply after the emergency response of the elastic distribution network after the fault occurs, firstly, the power flow modeling is carried out for the existing state of the distribution network, and secondly, the The lowest cost of post-disaster recovery strategy is the optimization goal. The three recovery strategies of network reconstruction, diesel generator or MESS, and gas turbine are optimized and adjusted, and the model is solved by minimizing the cost as the objective function. Finally, it is judged whether the formed microgrid meets the requirements of reliable operation. condition, if the operation condition is satisfied, the optimal post-di...

The invention discloses a post-disaster recovery control method for an elastic distribution network based on an electric-gas integrated energy system, which includes: modeling the power flow of the network according to the fault; Three post-disaster recovery measure models of structure, diesel generator and gas turbine are used to obtain the optimal coordination scheme; judge whether the formed microgrid meets the reliability operation conditions, and if not, move the MESS with the optimal path until the formed microgrid meets the reliability requirements. Sexual operating conditions. This disclosure is based on the comprehensive electricity-gas integrated energy energy distribution network post-disaster recovery control operation method, through network reconstruction, diesel generators or MESS and natural gas network through three optimization strategies of energy supply through gas turbines, the post-disaster recovery strategy cost is the lowest optimization The goal is to improve the elasticity of the distribution network, and to save the lost load as the load constraint condition, to ensure the rapid and effective restoration of the maximum power supply load.
Description
technical field [0001] The disclosure belongs to the technical field of elastic distribution network system optimization, and in particular relates to a post-disaster recovery control method for an elastic distribution network based on an electric-gas integrated energy system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] In recent years, with the increase of global temperature and the increasing environmental pollution, extreme weather has occurred frequently. According to statistics, an average of 9.09 typhoons are registered in my country every year. Extreme events such as typhoons, earthquakes, and blizzards will not only cause economic losses, but also threaten people's lives and hinder social and economic development. The use of electric energy has penetrated into all aspects of life. If you want to reduce economic losses, speed ...
