Abstract DC microgrid is an important part of the new power system. However, microgrids are prone to a wide range fluctuations in bus voltage when subjected external disturbances, which affects stability their own operation. This paper proposes control strategy photovoltaic unit and energy storage two modes, on this basis, adopts large-signal analysis method design filtering link constant load loop, adds damping filter circuit loop order inhibit generation resonance spikes, ensures dc presence large disturbances. The equivalent weight used estimate lifetime battery. Taking maximum daily net gain, minimum battery charge/discharge carbon dioxide emission as objective functions, optimal Pareto solution set initially obtained by multi-objective gray wolf algorithm, then using TOPSIS algorithm. related experiments proves that can be improved increasing capacitance value decreasing inductance value. Under paper, fluctuation amplitude most phases only 1.5%, shows optimization achieves effective suppression dips optimizes capability stability.
