Regional comprehensive energy system optimization scheduling method considering disaster recovery

Abstract

The invention discloses a regional comprehensive energy system optimization scheduling method considering disaster recovery. The method comprises the following steps: firstly establishing an economicdispatching model and an energy storage maximization dispatching model, then carrying out weighted fuzzy processing on the economic dispatching optimization model and the energy storage maximization dispatching optimization model, establishing a regional comprehensive energy system optimization dispatching model considering disaster recovery, and carrying out solving to obtain an operation mode. According to the invention, the problem that the regional integrated energy system does not have disaster recovery resistance during economic operation can be avoided; the problem that the cost is toohigh when the regional integrated energy system operates with disaster recovery as the target can be avoided, and the contradiction relation between the economy and disaster recovery resistance of system operation can be well balanced according to the occurrence probability of natural disasters and the damage condition to the system after occurrence.

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 uncer...
