含移动应急资源电-气综合能源系统的协调恢复优化
Coordinated restoration optimization of power-gas integrated energy system with mobile emergency sources
摘要
Abstract
In an integrated energy system(IES)composed of multiple subsystems,energy coupling causes an energy supply blockage or shutdown in one subsystem,thereby affecting the energy flow distribution optimization of other subsystems.The energy supply should be globally optimized during the IES energy supply restoration process to produce the highest restoration net income.Mobile emergency sources can be quickly and flexibly connected to supply energy after an energy outage to ensure a reliable supply to the system,which adds complexity to the decision.This study focuses on a power-gas IES with mobile emergency sources and analyzes the coupling relationship between the gas distribution system and the power distribution system in terms of sources,networks,and loads,and the influence of mobile emergency source transportation.The influence of the transient process caused by the restoration operation of the gas distribution system on the power distribution system is also discussed.An optimization model for power-gas IES restoration was established with the objective of maximizing the net income.The coordinated restoration optimization decision-making process was also built to realize the decoupling iteration of the power-gas IES,including system status recognition,mobile emergency source dispatching optimization,gas-to-power gas flow optimization,and parallel intra-partition restoration scheme optimization for both the power and gas distribution systems.A simulation test power-gas IES consisting of an 81-node medium-voltage power distribution network,an 89-node medium-pressure gas distribution network,and four mobile emergency sources was constructed.The simulation analysis verified the efficiency of the proposed coordinated restoration optimization method.关键词
