摘　　要：为实现集成智能楼宇(intelligent building,IBs)的主动配电网(active distribution network,ADN)灵活运行,该文提出一种基于机会约束规划的含IBs的ADN分布式能量管理策略。首先,基于建筑物的热惯性,构建含空调柔性负荷的IBs数学模型;其次,综合考虑楼宇侧与网络侧的运行约束,建立基于Dist Flow的集成IBs的ADN数学模型;然后,考虑到光伏(photovoltaic,PV)出力与外界温度的不确定性,利用机会约束规划将集成IBs的ADN优化问题转化为混合整数二阶锥规划(mixed integer second-order cone programming,MISOCP)问题;最后,为了保护配电网运营商与用户的隐私性,利用交替方向乘子法(alternating direction method of multipliers,ADMM)实现了集成IBs的ADN的分布式能量管理。基于ADMM的解耦机制,原MISOCP问题可以被分解为楼宇侧的混合整数线性规划(mixed-integer linear programming,MILP)子问题以及网络侧的二阶锥规划(second-order cone programming,SOCP)子问题进行求解。结果表明,在保障各主体信息隐私性的前提下,所提策略利用IBs灵活性实现了集成IBs的ADN全局最优能量管理。To achieve the flexible operation of active distribution network(ADN)with intelligent buildings(IBs),a distributed energy management strategy for ADN incorporating IBs based on chance-constrained programming is proposed.First,a mathematical model of IBs with air conditioner flexible loads is constructed based on the building thermal inertia.Secondly,the mathematical model of ADN with IBs based on DistFlow is developed by considering the operational conditions of building and network sides.Then,considering the uncertainties in photovoltaic(PV)output and ambient temperature,the ADN optimization problem with IBs is transformed into a mixed integer second-order cone programming(MISOCP)problem using chance-constrained programming.Finally,to protect the privacy of distribution network operators and customers,the alternating direction method of multipliers(ADMM)is leveraged to achieve distributed energy management of the ADN with IBs.According to the ADMM decoupling mechanism,the original MISOCP problem can be decomposed into a building-side mixed-integer linear programming(MILP)sub-problem and a network-side second-order cone programming(SOCP)sub-problem for solving.The results demonstrate that the proposed strategy can capitalize on the flexibility of IBs to achieve global optimal energy management of the ADN with integrated IBs,while protecting the privacy of each subject’s information.
