In modern distribution system,the distribution system operator(DSO)acts as a market facilitator and data manager as well as an energy supplier and operation *** this circumstance,the DSO should comprehensively consider the diversified participants of the modern distribution system when making investment decisions of distributed generation(DG).This paper proposes a DG planning model considering the behavior of the diversified participants,which are motivated to cooperate with distributed renewable energy resources to promote their integration,and to achieve the optimal DG investment *** optimization model takes a centralized structure but fully considers the preferences,profits and comfort levels of the aggregators and *** model is linearized into a mixed-integer linear programming(MILP)problem and is solved by *** of the case study show that when the DSO spares subsidies to the aggregators and consumers to encourage their participation in demand response(DR)programs,it earns more compared with providing no subsidies for DR *** is also demonstrated that the overall profit increases as the subsidies increase within a certain range,but decreases when the subsidies exceed this ***,the DSO needs to carefully choose the subsidization level to achieve the optimal utilization of renewable energy and demand *** optimal subsidization level is derived from the model proposed in this ***,this paper puts forward a new pattern to utilize the distributed renewable energy sources,and provides guidance in policy making and DR program implementation.

分布式充放电控制在降低问题求解难度、保护用户隐私方面具有集中式控制无法比拟的优势。给出了分布式充放电控制一般流程。针对现有方法仅能平抑负荷波动的局限性,提出了一种基于拉格朗日松弛法的分布式充放电控制方法,实现电动汽车与发电机组的协调运行,降低发电成本。该方法以对偶因子作为调度信号,通过对偶因子的更新逐渐逼近集中控制最优解。IEEE-RTS1979算例分析证实,该方法降低发电成本的效益更为显著,对大规模电动汽车群适应性更强;能够解决目标函数非凸、约束耦合的发电成本最小化问题,适用范围更广。
