    摘要:

    针对光伏发电的功率波动和消纳问题，结合中国西北地区供电供热需求，以光伏、热泵和混合储能组成的电—热联合微网为研究对象，研究了基于波动参数的多类型储能协同控制。首先，分析电—热联合微网的特点及能量转换方式。然后，设计电—热联合微网中基于波动参数的多类型储能双层协同控制策略，在上层控制中，基于功率波动时间尺度以及变参数的低通滤波方法，提出多类型储能协同平抑功率波动策略；在下层控制中，基于混合储能平抑功率波动以及微网电压、频率机理，提出混合储能能量转移的自适应控制策略。最后，通过仿真算例对所提算法进行验证，仿真结果表明：所提方法可以在有效减少电储能投资成本的前提下充分抑制可再生能源的功率波动，并延长混合储能的使用寿命，具有良好的应用前景。

    Abstract:

    To deal with the power fluctuation and the consumption of photovoltaic power generation with the premise of the demand of power supply and heating in northwest China, this paper studies the collaborative control of multi?types of energy storage based on fluctuation parameters by taking the electric?thermal joint micro?network composed of photovoltaic, heat pump and hybrid energy storage as the research object. Firstly, the characteristics and energy conversion mode of electro?thermal joint microgrid are analyzed. Then, a two?layer collaborative control strategy of multi?type energy storage based on fluctuation parameters is designed for the electro?thermal joint micro?grid. In the upper layer, a strategy of multi?type energy storage collaborative power fluctuation suppression is proposed based on the time?scale of power fluctuation and the low?pass filtering method with variable parameters. In the lower layer, an adaptive control strategy for energy transfer of hybrid energy storage is proposed based on the requirement of the power fluctuation suppression and the mechanism of voltage and frequency in microgrid. Finally, the proposed algorithm is verified by simulation. The simulation results show the proposed method can suppress the power fluctuation of renewable energy and can extend the battery life on the premise of reducing the investment cost of electric energy storage effectively.
