| 在构建安全稳定、经济低碳的智能电网的过程中，利用柔性负荷主动参与电网的协同控制受到高度重视。为挖掘和利用柔性负荷响应电网需求的调控潜力，提出一种专门针对柔性负荷的虚拟电厂构架；选取冰蓄冷空调作为典型受控对象，给出一种优先保障用户用电体验和经济性并计及电力系统供需关系的优化用电控制策略；结合空调系统的实际运行特性和用户用电期望，以设备运行费用最低、电网负荷波动最优为目标构建双层优化模型。通过算例在不同冷负荷需求下对冰蓄冷空调的控制结果进行仿真对比，验证了所提控制策略的可行性和有效性。 |

| Abstract: |
| In the process of building a safe, stable, economical and low-carbon smart grid, it has attracted high attention to use the flexible loads for active participating in the coordinated control of power grid. In order to exploit and utilize the regulation potential of flexible loads, a framework of virtual power plant specially designed for flexible loads is proposed. The ice storage air conditioning is selected as a typical controlled object, and an optimal control strategy of power consumption is proposed, which gives priority to users’ experience and economy, and considers the supply and demand relation of power grid. A two-layer optimal model is built according to the actual operation characteristics of air conditioning system and user expectation of power consumption, which takes the minimum operation cost and optimal load fluctuation as its objectives. The control of ice storage air conditioning under different cold load requirements is simulated and compared by cases, which verifies the feasibility and effectiveness of the proposed control strategy. |
