The island condition is the main factor causing the droop of the hybrid energy storage microgrid.To ensure the normal operation of hybrid energy storage microgrids,a droop flatness control method based on Markov Monte Carlo algorithm for island mode hybrid energy storage microgrids was proposed.The Markov Monte Carlo algorithm was employed to fill in missing photovoltaic data.Based on the filled microgrid photovoltaic data,the state of charge of the microgrid itself was calculated,and a hybrid energy storage microgrid supercapacitor and battery power control model was established based on the state of charge value to achieve island mode hybrid energy storage microgrid droop flattening control.The results show that the proposed method has a filling efficiency over 0.99 when filling photovoltaic data,and has good droop flatness control ability.The proposed method can effectively control the droop of the island mode hybrid energy storage microgrid,thereby ensuring the smooth operation of the hybrid energy storage microgrid,which has certain application value.
