摘要
为降低户用太阳能热泵供暖机组运行费用,实现清洁供暖,设计一套光储直流微电网为热泵供暖机组供电。对蓄电池储能单元的充放电工作过程进行分析,研究储能单元的电压外环、电流内环控制策略。应用软件搭建户用热泵供暖直流微电网仿真模型,仿真结果验证了光储直流微电网控制策略的可行性和稳定性。
In order to reduce the operating cost of the household solar heat pump heating unit and realize clean heating,a set of solar-storage DC microgrid is designed to supply power for the heat pump heating unit.The charging and discharging process of the battery energy storage unit are analyzed,and the voltage outer loop and current inner loop control strategy of the energy storage unit are studied.The simulation model of household heat pump heating DC microgrid is built by using the software.The simulation results verify the feasibility and stability of the optical storage DC microgrid control strategy.
