摘要
为充分发挥多种类热泵机组特性、提高区域低品位热源利用率,文章提出了基于多热源电热协同网络的时域柔性协调控制策略,采用有限状态机控制器对电热协同网络的热能调控、电能调控分别进行模式划分,在不同运行模式下制定了不同的运行逻辑,并利用模糊自适应PI控制器实现建筑室内温度与储能水箱温度的调控与监测,保持整个电热协同网络在任何气候条件下均能够稳定高效地运行。搭建联合仿真平台,其全年动态仿真运行结果表明,基于多热源电热协同网络的时域柔性协调控制策略,可以实现不同工况下的动态模式选择,建筑室内温度与储能水箱温度得到了优异的控制效果,白天建筑室内温度波动范围减小了19.61%,提高了建筑舒适性,与常规运行相比,负荷侧年累计电量降低了54.47%,节省下的电量使得电热协同网络从外部补充供电转变为向外部送电,减少能源消耗的同时有利于新能源消纳。
To fully leverage the characteristics of diverse heat pump units and enhance the utilization efficiency of regional low-grade heat sources,this study proposes a time-domain flexible coordination control strategy based on a multi-heat-source electro-thermal coordinated network.A finite state machine controller is employed to partition the operational modes for thermal and electrical regulation within the network.Distinct operational logics are formulated under different modes,while a fuzzy adaptive PI controller is utilized for the regulation and monitoring of indoor building temperature and energy storage tank temperature,ensuring stable and efficient operation of the entire electro-thermal coordinated network under any climatic conditions.A co-simulation platform is established,with annual dynamic simulation results demonstrating that the proposed strategy enables dynamic mode selection across varying operational scenarios.Both indoor building temperature and energy storage tank temperature achieve superior control performance:daytime indoor temperature fluctuations are reduced by 19.61%,significantly improving building comfort.Compared to conventional operations,the annual cumulative electricity consumption on the load side decreases by 54.47%.The conserved energy transforms the network from an external power consumer to a power supplier,reducing energy consumption while facilitating renewable energy integration.
