In view of the absorption and fluctuation of the renewable energy and the long-term demand of power combined with heat supply in northwest China, a collaborative control method of multi-type energy storage system based on PV power fluc-tuation characteristics is proposed. The characteristics of the microgrid with combined heat and power system for heat-pump heating, PV power station and hybrid energy storage system and the energy conversion modes in the system are analyzed. For PV power stabilized by heat pump and hybrid energy storage system, low-pass filtering method with variable parameters is adopted to deal with the PV output fluctuations using different time scales of fluctuations. Output fluctuations of large time scales can be stabilized by heat-pump, while fluctuations of small and medium time scales can be stabilized by hybrid energy storage. In the hybrid energy storage system, battery provides the power after the super capacitor has sta-bilized the fluctuations. So it can avoid frequent charging and discharging of the battery. The results in the example show that the collaborative control strategy is effective and makes the system flexible.
