An Optimal Scheduling Method for Regional Integrated Energy System Considering Disaster Restoration

Abstract

An optimal scheduling method for regional comprehensive energy systems considering disaster resistance recovery. Firstly, the economic scheduling model and the energy storage maximization scheduling model are established, and then the economic scheduling optimization model and the energy storage maximization scheduling optimization model are weighted and fuzzy processed to establish disaster resistance. The restored regional comprehensive energy system optimizes the scheduling model, solves it, and obtains the operation mode. The present invention can not only avoid the problem that the regional comprehensive energy system does not have disaster resistance and recovery ability during economic operation, but also avoid the problem of high cost when the regional comprehensive energy system operates with disaster resistance and recovery as the goal, and can be well based on the occurrence probability of natural disasters and the damage to the system after the occurrence, to balance the contradictory relationship between the economy of system operation and the ability to resist and recover from disasters.

Description

technical field [0001] The invention belongs to the field of optimal scheduling of regional comprehensive energy systems, and relates to an optimal scheduling method of regional comprehensive energy systems considering disaster resistance and recovery. Background technique [0002] With the rapid development of society and economy, the demand for energy use and the pressure of environmental degradation are increasing day by day. The third industrial revolution centered on the Energy Internet is going on, and it is an inevitable choice to solve energy and environmental problems. The regional comprehensive energy system includes multiple energy systems such as electric energy, natural gas, and heat energy. Different energy sources are coupled with each other, transformed into each other, and complement each other in energy use. The regional comprehensive energy system is an important form of the Energy Internet. The regional comprehensive energy system can achieve clean and ef...

Problems solved by technology

[0005] (1) The existing regional integrated energy system dispatching generally takes the lowest operating cost of the system as the dispatching goal, that is, the operating economic goal. However, after a sudden natural disaster under this goal, the regional integrated energy system cannot respond quickly Resilience to disasters, resulting in power, natural gas and heat customers across the system being forced to stop supply, resulting in severe power loss, gas loss and heat loss

[0006] (2) The occurrence of natural disasters is uncertain and sudden. If the regional integrated energy system formulates its operation mode to prepare for natural disasters at all times, the operating cost of the regional integrated energy system will be too high if no natural disasters occur. Excessive operating costs are paid for potential small probability natural disasters

[0007] It can be seen that there is a difficult problem of reconciliation between the guaranteed economy of the optimal dispatch of the regional integrated energy system and the ability to recover from natural disasters
