摘　　要：为安全、经济、公平的消纳分布式光伏,以整县光伏为研究场景,提出了一种考虑调控和交易模式影响的中低压分布式光伏协调配置方法。首先,分析了多电压等级协调和交易模式对分布式光伏接纳能力的影响。其次,以两个电压等级光伏并网容量为控制变量,建立联合考虑经济效益和调控能力多目标优化模型,目标一是多主体经济性最优,建立3种交易模式下各主体效益模型,并采用凸化和卡罗需-库恩-塔克条件转化为单层求解;目标二是计及电压调控能力的多电压等级消纳量最大,采用关联决策变量方法与目标一统一求解。最后通过中低压配网算例仿真,验证了所提模型的有效性和优越性,可为市场环境下分布式光伏多电压等级协调配置提供决策参考。In order to promote the distributed PV consumption safely,economically and equitably,taking the distributed countywide PV as the research scene,a coordinated configuration method of the medium-and low-voltage distributed network with distributed PV considering the influence of regulation and trading modes is proposed.Firstly,the influence of multi-voltage-level coordination and trading modes on the distributed PV hosting capacity is analyzed.Secondly,with the PV hosting capacity of the two voltage levels as the control variable,a multi-objective optimization model considering the economic benefit and the regulation capability is established.The first goal is to optimize the multi-agent economic.The benefit models of each agent under three trading modes are established and transformed into a single-layer mode by the convex and the Karush-Kuhn-Tucker condition.The second goal is the maximum PV hosting capacity of multi-voltage levels.The voltage regulation ability is considered and the model is solved uniformly with the first goal by using the method of associated control variable.Finally,the efficiency and superiority of the proposed model are verified through the simulation of the medium-and low-voltage distribution network,providing a reference for the coordinated configuration of distributed PV in the multi-voltage-level under the market environment.
