【摘要】：分布式冷热电联供系统(distributed combined cooling,heating and power system,DCCHP)因其高效的能源利用率成为区域综合能源系统的有效实现形式,同时随着需求侧响应(demand response,DR)技术的发展,通过管控用户用能行为来提高能源系统性能成为目前研究的热点。基于此,文章建立了区域能量管理系统(regional energy management system,REM S)并提出了一种基于DR的DCCHP能量管理策略。在用户侧,对系统负荷进行分类并建立考虑用户满意度反馈及动态费用补偿的DR控制模型。REMS用能方式管控子系统,针对冷热电负荷各自的特点及组成,以DR补偿费用及负荷峰谷差最小为目标优化初始负荷曲线形态。在供能侧,将优化后的负荷数据输入REMS设备出力调度子系统,以DCCHP综合成本最小为目标经济管控系统设备出力。算例仿真结果证明所提策略可有效提高系统能源利用率、降低成本,实现供需双侧的共同优化。
[Abstract]:Distributed combined cooling and power system DCCHPs (distributed combined cooling and power system DCCHPs) become an effective implementation form of regional integrated energy systems due to their high energy efficiency. Meanwhile, with the development of demand response to demand response (DCCHPs) technology on the demand side, To improve the performance of energy systems by controlling user energy use behavior has become a hot topic. Based on this, a regional energy management system REM S is established and a DCCHP energy management strategy based on Dr is proposed. On the user side, the system load is classified and a Dr control model considering customer satisfaction feedback and dynamic cost compensation is established. The initial load curve shape is optimized with Dr compensation cost and minimum load peak and valley difference as objectives. On the power supply side, the optimized load data is input into the output dispatch subsystem of REMS equipment, and the minimum integrated cost of DCCHP is taken as the target of the equipment output in the economic control system. The simulation results show that the proposed strategy can effectively improve the energy efficiency of the system, reduce the cost and achieve the joint optimization of supply and demand.
