摘　　要：变频空调是电力系统供需调节和新能源消纳的优质灵活资源之一。但其功率调节过程非连续,响应存在强不确定性延时,难以快速、精准跟踪新能源出力的随机变化。因此,提出了一种电池-变频空调的复合储能模型和运行控制策略,以实现建筑屋顶波动光伏的友好并网和本体消纳。首先,考虑楼宇房间热动态等因素,建立了楼宇、电池和变频空调的精细化功率-能量模型,并基于实验数据量化了变频空调运行功率的不连续调节曲线和响应过程的不确定延时曲线。随后,提出了变频空调的分段滞回温度控制策略以减少空调温度的调节次数,保证了用户舒适性。同时建立了储能-变频空调多时间尺度功率能量互补控制框架,利用电池的灵活性补偿空调的欠调和超调,解决了空调响应的功率偏差和延时不确定问题。最后,基于真实的屋顶光伏数据集,仿真验证了所提出的复合储能优化策略在降低储能电池配置容量、减少电池充放电能量、促进光伏友好并网和本体消纳方面的有效性。The inverter air conditioner(IAC) is one of the high-quality and flexible resources for power system regulation and renewable energy resources(RES) accommodation.However, it has a non-continuous power regulation and its response has a strong uncertainty delay, which makes it difficult to quickly and accurately track the random fluctuations of the RES. Therefore, a Battery-IAC compound energy model and its control strategy are proposed so as to achieve the friendly grid connection and local accommodation of the fluctuated photovoltaics(PV) on the rooftops of the buildings.First, considering the room thermal dynamics inside the buildings, the power-energy models of the buildings, the batteries and the IACs are established. Based on the experimental data, the discontinuous curve and the uncertainty delay curve of the response of the IAC are quantified.Subsequently, the temperature segment control strategy of the IAC is proposed in order to reduce the regulation times of the temperature, promising the users’ comfort level. A multi-time power and energy complementary control framework for the Battery-IAC system is established. The undershoot and overshoot adjustments of the IAC are compensated by utilizing the batteries, eliminating the problem of power deviation and uncertain delay of the IAC response. Finally, by using the real rooftop PV data sets, the simulations verify the effectiveness of the proposed Battery-IAC compound energy storage optimization strategy in reducing the auxiliary capacity of batteries and battery charging and discharging energy, and promoting the PV friendly grid connection and local accommodation.
