计及反弹负荷平抑的空调集群直接负荷控制研究

Research on Air Conditioning Cluster Direct Load Control Considering Rebound Load Suppression

针对传统模型对需求响应的直接负荷控制过程中,对用户空调负荷自主退出问题以及控制结束后的负荷反弹现象考虑不足等问题,研究了直接负荷控制项目的实施过程,分析了导致用户退出直接负荷控制的因素,并以负荷反弹为切入点,给出负荷削减需求结束后允许用户在一定时间内继续受控的直接负荷控制(direct load control,DLC)长控方案,并建立以需求侧实际负荷削减量与需求偏差最小为目标的直接负荷控制调度和以机组经济性为目标的供需双方协同优化调度模型。算例仿真结果表明,所提控制方案能在满足需求响应实施方的负荷削减要求、提高机组调度能力的同时有效平抑反弹负荷。

Aiming at the problem of user's self exit in the process of control and the phenomenon of load rebound after the end of control in the traditional model of demand side direct load control,it analyzes the implementation process of direct load control of demand response project,studies the reasons for users'withdrawal from direct load control,and the influence of control strategy and user type on load rebound.It gives load reduction accordingly the DLC(direct load control)long-term control scheme allows users to continue to be controlled for a certain period of time after the end of demand.A double-layer scheduling model of alternating optimization between direct load control scheduling of upper demand side and economic dispatch of lower level units is established.The simulation results show that the proposed control scheme can effectively suppress the rebound load while meeting the load reduction requirements of the demand-responder and improving the unit scheduling capacity.
