摘　　要：目前我国因风电与光伏发电产生的可再生能渗透率增高,导致灵活性资源匮乏问题日益突出,因风电和光伏等新能源发电的波动性和不确定性导致电网调峰及保供安全存在较大压力,同时电力市场机制没有完全建设起来,电价市场化机制不够成熟,需求侧响应资源没有被积极的调动。随着我国电动汽车保有量的不断增高,同时电动汽车的无序入网会造成“峰上加峰”的不良影响,因此可以合理安排电动汽车进行有序入网参与需求响应,文中首先介绍了电动汽车参与需求响应产生的积极影响;其次,探究了电动汽车参与需求相应的方式,并确定了以聚合商的方式参与需求响应;然后,设计了电动汽车聚合商的有序充放电策略,提出了电动汽车负荷聚合商参与需求响应的思路,构建了需求响应的交易机制;最后以电动汽车用户、电动汽车负荷聚合商平台与电网共同获益为目标,制定了电动汽车充放电的上下限,并运用数值模拟进行验证,结果表明,在电动汽车聚合商的模式下,通过充放电电价引导用户对充电时段的选择,可以实现三方获益的目标,并且对实现电网系统“削峰填谷”具有一定的效果。At present,due to the increase in the penetration rate of renewable energy generated by wind power and photovoltaic power generation in China,the problem of lack of flexible resources is becoming increasingly prominent,and the volatility and uncertainty of new energy power generation such as wind power and photovoltaic power generation lead to greater pressure on the peak regulation and supply security of the power grid,and the power market mechanism has not been fully constructed,the market-oriented mechanism of electricity price is not mature enough,and the demand-side response resources have not been actively mobilized.With the continuous increase of the number of electric vehicles in China,and the disorderly access of electric vehicles will cause the adverse impact of“peak on peak”,so it is reasonable to arrange electric vehicles to participate in demand response in an orderly manner.Secondly,the ways in which electric vehicles participate in demand are explored,and the participation in demand response in the form of aggregators is determined.Then,the orderly charging and discharging strategy of electric vehicle aggregators is designed,the idea of electric vehicle load aggregators participating in demand response is proposed,and the trading mechanism of demand response is constructed.Finally,with the goal of benefiting electric vehicle users,electric vehicle load aggregator platform and power grid,the upper and lower limits of electric vehicle charging and discharging are formulated,and numerical simulation is used to verify them.
