近年来,以台风为代表的极端自然灾害导致城市配电网停电事故频发,给城市电网的持续供电带来挑战。在电动汽车(EV)用户群体数量快速增长的背景下,针对上述问题,提出了一种基于车辆并网(V2G)的城市配电网弹性提升策略,以增强城市电网应对台风灾害的能力。首先,建立配电网元件故障率模型,通过随机抽样生成台风灾害下的配电网故障场景;其次,考虑即将到来的台风灾害对道路拥堵情况及用户出行意愿的影响,搭建了灾害前期EV调度模型;然后,基于消费者心理学理论,制定灾后反向输电激励响应机制,引导V2G站点内的EV参与供电恢复;最后,考虑配电网重构及V2G站点反向充电,制定V2G参与的灾后供电恢复策略。由算例分析可知,与应急发电车相比,V2G参与供电恢复的方案经济性及恢复效果更优,验证了所提弹性提升策略的可行性与有效性。
In recent years
extreme natural disasters represented by typhoons have led to frequent power outages in urban distribution networks
which has brought challenges to the sustainable power supply of urban power grids. Under the background of the rapid growth of the number of electric vehicle (EV) user groups
aiming at the above problems
a vehicle-to-grid (V2G) based resilience promotion strategy for the urban distribution network is proposed to enhance the ability of urban power grid to deal with typhoon disasters. Firstly
the failure rate model of the distribution network component is established
and the distribution network failure scenarios under typhoon disasters are generated by random sampling. Secondly
considering the impact of the upcoming typhoon disaster on the road congestion and users’ travel intention
an EV scheduling model in the early stage of the disaster is established. Then
based on the theory of consumer psychology
the post-disaster incentive response mechanism for the reverse power transmission is formulated to guide EVs in the V2G station to participate in the power supply restoration. Finally
considering the reconfiguration of the distribution network and the reverse charging of V2G stations
the post-disaster power supply restoration strategy with the participation of V2G is formulated. The example analysis shows that
compared with the mobile emergency generator (MEG)
the scheme of V2G participating in the power supply restoration has a better economy and restoration effect
which verifies the feasibility and effectiveness of the proposed resilience promotion strategy.
