基于温控负荷的孤立微电网频率的协调控制方法及系统
摘要：
本发明公开一种基于温控负荷的孤立微电网频率的协调控制方法及系统，在保证用户舒适度的同时，应用温控负荷的改进变参与度调频方法和储能装置调频方法的协同作用，实现微电网系统频率的二次调节，不仅能够充分发挥温控负荷的调频能力，且可以更有效地减小对储能装置的容量需求，从而能够更好地提高微电网频率控制效果。所述方法包括：S1、基于改进的用户参与度系数KAC对微电网进行调频，其中，kf为原始用户参与度系数，on％为稳定运行状态下温控负荷处于开启状态的比例，PN为温控负荷的额定功率，T+和T‑分别为设定的温控负荷开启和关闭的温度限值；S2、基于储能装置对微电网进行再次调频。
摘要（英）：

The invention discloses a method and system for coordination control of isolated microgrid frequency based on a temperature control load, while ensuring the comfort level of users, uses a synergistic effect of an improved variable participation degree frequency modulation method for the temperature control load and an energy storage device frequency modulation method to realize secondary adjustment of microgrid system frequency, can give full play to a frequency modulation capability of the temperature control load, and can effectively lower a requirement for the capacity of the energy storage device, thereby well improving a microgrid frequency control effect. The method includes the steps of: S1. performing frequency modulation on a microgrid based on an improved user participation degree coefficient K, K=on%P/(T<+>-T<->)*k, wherein k is an original user participation degree coefficient, on% is the proportion of the temperature control load in an on state under a stable running state, P is rated power of the temperature control load, and T<+> and T<-> are set temperature limits for switching-on and switching-off of the temperature control load; and S2. performing frequency modulation on the microgrid again based on the energy storage device.
